and U.S. Patent Application Publ. No. 2017/0254259, published Sep.
7, 2017, (hereinafter referred to as the "REFERENCE APPLICATIONS")
are hereby incorporated by reference in their entirety.
BACKGROUND OF THE INVENTION
[0004] Worldwide emissions, stemming primarily from the burning of
fossil fuels, are reaching the highest levels ever recorded. By
some measures, the emissions associated with burning fossil fuels
have already reached nearly 5 metric tons/person/year. Internal
combustion engines, including diesel engines, are a major
contributor of fossil fuel emissions. In fact, by some measures,
there are over 300 million diesel engines worldwide.
[0005] Internal combustion engines, and diesel engines in
particular, emit particulate matter (PM) and governments around the
world are realizing that these emissions are a cause for great
concern. As a result, many countries/jurisdictions, including the
United States, the European Union and China, are passing
regulations which require significantly reduced emissions from
internal combustion engines, including diesel engines.
[0006] Accordingly, more and more, businesses are forced to comply
with these new air quality standards at their own expense.
Sometimes, the costs for modifying a large internal combustion
engine installation to meet new regulations can exceed US $30,000
per engine.
[0007] An attributable amount of emissions created by internal
combustion engines is a result of the internal combustion engines
failure to convert all of the energy available in the hydrocarbon
fuel (e.g., gasoline and/or diesel fuel). This incomplete
conversion is often a result of what is commonly referred to as
incomplete combustion of the fuel. Incomplete combustion results in
an unnecessary loss of fuel efficiency and an increase in
pollution.
[0008] Accordingly, it is desirable to have a system and/or method
for use with an internal combustion engine that aids in achieving
more complete combustion of the hydrocarbon fuel, reduced
emissions, and/or better fuel economy, or otherwise improves
certain metrics of the internal combustion engine.
BRIEF SUMMARY OF THE INVENTION
[0009] Certain embodiments may provide, for example, a method for
increasing fuel economy of an internal combustion engine. In
certain embodiments, for example, the method may comprise
introducing in the range of 1.25-30 liters (for example in the
range of 2-5 liters) of HHO gas per hour per liter of displacement
of the internal combustion engine. In certain embodiments, for
example, the method may comprise combusting a quantity of
carbonaceous fuel in the presence of the introduced HHO gas to
increase fuel economy of the carbonaceous fuel by at least 5% (for
example at least 10% or at least 20%).
[0010] In certain embodiments, for example, the method may further
comprise electrolyzing an aqueous electrolyte solution at an
average (or maximum) current draw of less than 20 amps (for example
less than 15 amps or in the range of 9-15 amps, in the range of
9-12 amps, or in the range of 10-15 amps) to form the HHO gas. In
certain embodiments, for example, the aqueous electrolyte solution
may comprise no more than 3 wt. % of any salt (for example no more
than 3 wt. % potassium carbonate such as in the range of 1.5-3 wt.
% potassium carbonate). In certain embodiments, for example, the
electrolyzing may be performed with a total electrical resistance
of less than 20 ohm (for example less than 10 ohm or less than 3
ohm). In certain embodiments, for example, the internal combustion
engine may power a vehicle. In certain embodiments, for example,
the electrolyzing may occur onboard the vehicle. In certain
embodiments, for example, the electrolyzing may consume
electrolysis of up to 20 ounces (for example in the range of 4-10
ounces or up to 4-10 ounces) of the aqueous electrolyte per liter
displacement of the internal combustion engine per 10,000 miles
traveling distance of the vehicle. In certain embodiments, for
example, the vehicle may be a class 8 truck.
[0011] In certain embodiments, for example, the internal combustion
engine may be a gasoline engine. In certain embodiments, for
example, the internal combustion engine may be a diesel engine. In
certain embodiments, for example, the diesel engine may be a heavy
duty diesel engine sized to produce in the range of 430-500 hp. In
certain embodiments, for example, the internal combustion engine
may have a displacement in the range of 11-16 liters. In certain
embodiments, for example, the internal combustion engine may be
sized to produce in the range of 200-250 hp. In certain
embodiments, for example, the internal combustion engine may have a
displacement in the range of 6-11 liters. In certain embodiments,
for example, the internal combustion engine may be a generator set
engine. In certain embodiments, for example, the generator set
engine may have a displacement in the range of 6-60 liters. In
certain embodiments, for example, the generator set engine may have
a displacement in the range of 2-6 liters per cylinder. In certain
embodiments, for example, the generator set engine may be sized to
produce more than 1000 hp. In certain embodiments, for example, the
generator set engine may be sized to produce 1000-2000 hp. In
certain embodiments, for example, the internal combustion engine
may be a biofuel engine.
[0012] In certain embodiments, for example, the introducing may
comprise depositing air-free portions of the HHO gas (for example
portions of the HHO gas comprising less than 5 wt. % air, less than
1 wt. % air, less than 1000 ppm air, less than 500 ppm air, less
than 250 ppm air, or less than 100 ppm air) into an air stream
supply for a particular combustion chamber, within 3 inches (for
example within 1% inches or within 1 inch) of at least one
combustion chamber inlet orifice (for example an air intake
orifice) of the internal combustion engine.
[0013] In certain embodiments, for example, the method may reduce
one or more engine-out emissions (for example a nitrogen oxide
(NOx) emission) by at least 10%. The improvement in reduced
emissions may be relative to an internal combustion engine running
under identical or substantially identical conditions (for example,
taking into account engine load, average engine load, run-time,
average run-time, temperature, average temperature, speed, average
speed, rpm's, average rpm's, acceleration, average acceleration
and/or type of primary fuel) without HHO gas.
[0014] In certain embodiments, for example, the introduced HHO gas
may be no more than 500 ppm (for example in the range of 1-500 ppm,
no more than 250 ppm, in the range of 1-250 ppm, in the range of
1-100 ppm, in the range of 25-100 ppm, or in the range of 50-100
ppm) relative to the weight of the combusted quantity of
carbonaceous fuel.
[0015] In certain embodiments, for example, the method may reduce
exhaust temperature by at least 10.degree. F. (for example at least
20.degree. F. or at least 30.degree. F.).
[0016] In certain embodiments, for example, the HHO gas may be
substantially hydrogen.
[0017] In certain embodiments, for example, the method may further
comprise delivering HHO gas to a diesel particulate filter (DPF)
regenerator system.
[0018] In certain embodiments, for example, at least a portion of
the in the range of 1.25-30 liters of the HHO gas stream per hour
per liter of displacement of the internal combustion engine may be
passed through a heat exchanger prior to the introducing. In
certain embodiments, for example, the heat exchanger may receive an
engine exhaust stream. In certain embodiments, for example, the
engine exhaust stream may be used in the heat exchanger to heat the
HHO gas stream. In certain embodiments, for example, the heat
exchanger may receive an engine coolant stream. In certain
embodiments, for example, the engine coolant stream may be used in
the heat exchanger to adjust the temperature (for example, cooling
and/or heating) of the HHO gas stream.
[0019] In certain embodiments, for example, a portion of the
introduced HHO gas may be introduced to a first combustion chamber
of the internal combustion engine during a portion of an intake
stroke of a combustion cylinder, the combustion cylinder comprising
the combustion chamber. In certain embodiments, for example, the
portion of an intake stroke may be less than 50% of the intake
stroke. In certain embodiments, for example, the during a portion
of an intake stroke is when the intake stroke may be at an angle in
the range of 0-40.degree. from top-dead-center.
[0020] Certain embodiments may provide, for example, a method for
increasing fuel economy of an internal combustion engine (for
example by at least 3%, at least 4%, at least 5%, at least 6%, at
least 8%, or by at least 10%). The improvement in fuel economy may
be relative to the internal combustion engine running under
identical or substantially identical conditions (for example,
taking into account engine load, average engine load, run-time,
average run-time, temperature, average temperature, speed, average
speed, rpm's, average rpm's, acceleration, average acceleration
and/or type of primary fuel) without HHO gas. In certain
embodiments, for example, the method may comprise combusting a
quantity of carbonaceous fuel in at least one combustion chamber of
the internal combustion engine in the presence of no more than 500
ppm (for example in the range of 1-500 ppm, no more than 250 ppm,
in the range of 1-250 ppm, in the range of 1-100 ppm, in the range
of 25-100 ppm, or in the range of 50-100 ppm) HHO gas during cold
start (for example during the first 60 seconds of starting the
internal combustion engine, during the first 120 seconds of
starting the internal combustion engine, or during the first 180
seconds of starting the internal combustion engine). In certain
embodiments, for example, the combusting may achieve at least 97%
complete combustion of the quantity of carbonaceous fuel.
[0021] Certain embodiments may provide, for example, a method for
increasing fuel economy of an internal combustion engine. In
certain embodiments, for example, the method may comprise
introducing in the range of 2-5 liters of HHO gas per hour per
liter of displacement of the internal combustion engine. In certain
embodiments, for example, the introducing may comprise depositing a
first portion of the HHO gas in a first air stream within 3 inches
of a first combustion chamber inlet orifice of the internal
combustion engine. In certain embodiments, for example, the
introducing may comprise depositing a second portion of the HHO gas
in a second air stream within 3 inches of a second combustion
chamber inlet orifice of the internal combustion engine. In certain
embodiments, for example, the introducing may comprise depositing
at least a third portion of the HHO gas in at least a third air
stream within 3 inches of at least a third combustion chamber inlet
orifice of the internal combustion engine. In certain embodiments,
for example, the method may comprise combusting a quantity of
carbonaceous fuel in the presence of at least one of the deposited
first portion of the HHO gas, the deposited second portion of the
HHO gas, and the deposited at least a third portion of the HHO gas
to increase fuel economy of the carbonaceous fuel by at least
5%.
[0022] Certain embodiments may provide, for example, a method for
increasing fuel economy of an internal combustion engine during
cold start to achieve at least 85% (for example at least 90%, at
least 93%, at least 95%, at least 97%, at least 99%, at least
99.5%, or at least 99.9%) complete combustion of the quantity of
carbonaceous fuel during the first 60 seconds (or 120 seconds or
180 seconds) of starting the internal combustion engine. In certain
embodiments, for example, the method may comprise combusting a
first quantity of carbonaceous fuel in a first combustion chamber
of the internal combustion engine in the presence of no more than
500 ppm (for example in the range of 1-500 ppm, no more than 250
ppm, in the range of 1-250 ppm, in the range of 1-100 ppm, in the
range of 25-100 ppm, or in the range of 50-100 ppm) HHO gas,
relative to the quantity of carbonaceous fuel. In certain
embodiments, for example, the method may comprise combusting a
second quantity of the carbonaceous fuel in a second combustion
chamber of the internal combustion engine in the presence of no
more than 500 ppm (for example in the range of 1-500 ppm, no more
than 250 ppm, in the range of 1-250 ppm, in the range of 1-100 ppm,
in the range of 25-100 ppm, or in the range of 50-100 ppm) HHO gas,
relative to the quantity of carbonaceous fuel. In certain
embodiments, for example, the method may comprise combusting at
least a third quantity of carbonaceous fuel in at least a third
combustion chamber of the internal combustion engine in the
presence of no more than 500 ppm (for example in the range of 1-500
ppm, no more than 250 ppm, in the range of 1-250 ppm, in the range

least 10%, at least 15%, at least 20%, at least 25%, at least 30%,
at least 35%, at least 40%, at least 45%, or the method may reduce
carbonaceous fuel consumption per unit of work performed by at
least 50% compared to combusting the quantity of carbonaceous fuel
without the presence of the ultra low quantity of HHO gas. In

embodiments, for example, at least two of the plurality of
electrolysis plates may comprise a point for attaching to at least

be located in opposite corners. In certain embodiments, for
example, the electrolysis cell may further comprise an electrical
isolator between each pair of adjacent plates of the plurality of
electrolysis plates.
[0230] In certain embodiments, for example, the plurality of

coating). In certain embodiments, for example, an inner lining of
the pressure-resistant container may comprise an electric
insulator.
[0231] In certain embodiments, for example, the second defined

1 gallon). In certain embodiments, for example, the second defined
space may have a volume of no more than 10 gallons (for example no
more than 5 gallons). In certain embodiments, for example, the

pressure relief valve.
[0232] In certain embodiments, for example, the electrolysis cell

further comprise a housing. In certain embodiments, for example,
the pressure-resistant container may further comprise a seal

[0233] In certain embodiments, for example, the first defined space
may be configured to hold a volume of electrolyte solution to
supply a sufficient amount of HHO gas for at least 1 month (for
example at least 2 months) of operation of the host engine (i.e.,
the engine or engines it is supplying second fuel to). In certain
embodiments, for example, the first defined space may be configured
to hold a volume of electrolyte solution to supply HHO gas to a
truck for at least 30,000 miles of driving or 60,000,000 crankshaft
rotations. In certain embodiments, for example, the first defined

example, the electrolyte solution may comprise an aqueous
electrolyte solution with a concentration of electrolyte of less

[0234] Certain embodiments may provide, for example, an apparatus
for providing HHO gas for an internal combustion engine,
comprising: an electrolysis cell for generating the HHO gas, and a
plurality of HHO gas control valves (for example a plurality of
injectors) configured to deliver the HHO gas to a plurality of
intake ports of the internal combustion engine. In certain

the following embodiments may comprise each of the other
embodiments or parts thereof. In certain embodiments, for example,
the plurality of injectors may comprise a number of injectors at
least equal to a number of a plurality of engine cylinders. In
certain embodiments, for example, the plurality of injectors may be
designed to deliver the HHO gas within an intake manifold of the
engine (i.e. the HHO gas is not mixed or does not come into contact
with intake air until it is released from the tube (or lance)
connected to the respective injector). In certain embodiments, for
example, the plurality of injectors may deliver HHO gas within 3
inches (for example within 0.5 inches) from each intake port (or
orifice of the intake valve) of a plurality of cylinders. In
certain embodiments, for example, the plurality of injectors may be
positioned, configured, equipped, and/or designed to directly
inject into the combustion chamber (in a fashion similar or the
same as the primary fuel is injected into the combustion chamber in
some applications). In certain embodiments, for example, at least
one of the plurality of injectors may be positioned adjacent to at
least one of the plurality of engine cylinders, at least a second
injector of the plurality of injectors may be positioned adjacent
to at least a second cylinder of the plurality of engine cylinders,
and at least a third injector of the plurality of injectors may be
positioned adjacent to at least a third cylinder of the plurality
of engine cylinders In certain embodiments, for example, each of
the plurality of injectors may be equipped with a lance that

position proximate an intake port of a cylinder. The lances serve
to deliver the HHO gas deep into the intake port near (for example,
within 3 inches, or within 2 inches or between 0.5 to 2 inches or
less than 1 inch from) an orifice of the intake valve. In certain
embodiments, for example, the lance may deliver air-free HHO gas
into the intake port. In certain further embodiments, for example,
the HHO gas present in the lance may be air-free (or at least
substantially air-free). In certain embodiments, for example,
air-free (or substantially air-free) HHO gas provided by an
injector may mix with air inside a portion of the lance.

for providing HHO gas for an internal combustion engine,
comprising: an electrolysis cell for generating the HHO gas, and a
flow regulator configured to start and stop a flow of the HHO gas
from the electrolysis cell to a plurality of injectors of the
internal combustion engine. In certain embodiments, one or more
than one (including for instance all) of the following embodiments
may comprise each of the other embodiments or parts thereof. In
certain embodiments, for example, the apparatus may further
comprise a gas pressure regulator. In certain embodiments, for
example, the gas pressure regulator may control the gas pressure at
an outlet port. In certain embodiments, for example, the apparatus
may further comprise a heat exchanger. In certain embodiments, for
example, the heat exchanger may provide at least two separate fluid
paths, wherein the at least two separate fluid paths may be in
thermal communication. In certain further embodiments, for example,
at least one of the at least two separate fluid paths may be
configured to receive an engine coolant. In certain embodiments,
for example, at least one of the at least two separate fluid paths
may be configured to receive at least a portion of the gas
generated from the electrolysis cell. In certain embodiments, for
example, the heat exchanger may control the outlet temperature of
gas exiting an outlet port. In certain embodiments, for example,
the gas pressure regulator may be equipped with a heat exchanger
(for example the foregoing heat exchanger). In certain further
embodiments, for example, the gas pressure regulator may control
the outlet pressure and outlet temperature of gas exiting an outlet
port of the gas pressure regulator. In certain further embodiments,
for example, the gas exiting the gas pressure regulator may be
controlled to have a temperature greater than 35.degree. C. (for
example greater than 45.degree. C.). In certain embodiments, for
example, the HHO gas passing through the regulator may be cooled
and/or heated by exchanging heat through the heat exchanger with
engine coolant and therefore have a regulator exit temperature with
plus or minus 10 degrees, for example .+-.5.degree. C., of the
engine coolant temperature. In certain embodiments, for example,
use of the engine coolant to control the temperature of the HHO gas
and/or use of the pressure regulator to control the pressure of the
HHO gas may allow predetermined amounts of the HHO gas to be
introduced to at least one combustion chamber of a plurality of
combustion chambers of the internal combustion engine. In certain
embodiments, for example, the aforesaid temperature and pressure
control may provide more precise control over the amount of HHO gas
introduced into the internal combustion engine in comparison to a
system lacking said controls (for example a traditional system for
introducing electrolysis gases into an internal combustion
engine).
[0243] In certain embodiments, for example, the gas pressure
regulator pressure may be at least partially controlled relative to
an intake manifold pressure (for example, 5-25 psi, or 10-15 psi
higher than the air pressure in the intake manifold, downstream of
a turbocharger) of the internal combustion engine. In certain
embodiments, for example, the gas pressure regulator may be at
least partially controlled by pressure communicated from an intake
manifold pressure of the internal combustion engine. In certain
embodiments, for example, the gas pressure regulator may be
characterized by an opening pressure. In certain further
embodiments, for example, the opening pressure may be configured
based on the intake manifold pressure of the internal combustion
engine. In certain embodiments, for example, the gas pressure
regulator pressure may be at least partially controlled relative to
an intake manifold pressure (for example, 5-25 psi, or 5-15 psi, or
5-8 psi, or 10-15 psi higher than the air pressure in the intake
manifold, downstream of a turbocharger). In certain further
embodiments, for example, the intake manifold pressure may vary
based on and/or during the operation of the internal combustion
engine.
[0244] Certain embodiments may provide, for example, an apparatus
for providing HHO gas for an internal combustion engine,
comprising: an electrolysis cell for generating the HHO gas, and a
gas distribution harness comprising a plurality of tubes (or
lances) configured to deliver the HHO gas to a plurality of intake
ports of the internal combustion engine, for example a multi-point
injection system. In certain embodiments, one or more than one
(including for instance all) of the following embodiments may
comprise each of the other embodiments or parts thereof. In certain
embodiments, for example, the number of the plurality of lances may
be equal to a number of a plurality of injectors or at least one
injector, including all the injectors, may be fitted with multiple
lances, for example, two or more lances configured to provide two
or more points or injection for a single cylinder and/or provide
multi-points of injection for multiple cylinders (for example, four
injectors could each be fitted with, for example, two lances each
and the first injector could serve to inject HHO gas within the
intake port of the first and fourth cylinders of the host engine
and, similarly, the second and third injectors could serve to
inject HHO gas within the intake ports of the second and fifth
cylinders, and the third and sixth cylinders, respectively. In
certain embodiments, for example, at least one lance of the
plurality of lances may comprise at least one outlet, at least a
second lance of the plurality of lances may comprise at least a
second outlet, and at least a third lance of the plurality of
lances may comprise at least a third outlet. In certain
embodiments, for example, the at least one outlet may be positioned
within 3 inches (for example between 0.5 and 1.5 inches) of an air
flow port of at least one cylinder of a plurality of cylinders of
the internal combustion engine, the at least a second outlet may be
positioned within 3 inches (for example between 0.5 and 1.5 inches)
of an air flow port of at least a second cylinder of the plurality
of cylinders, and at least a third outlet may be positioned within
3 inches (for example between 0.5 and 1.5 inches) of an air flow
port of at least a third cylinder of the plurality of cylinders. In
certain embodiments, for example, the at least one outlet may be
positioned within 1 inch (for example within 0.25 inches) of an
engine valve seat of a plurality of engine valve seats of the
internal combustion engine, the at least a second outlet may be
positioned within 1 inch (for example within 0.25 inches) of a
second engine valve seat of the plurality of engine valve seats,
and the at least a third outlet may be positioned within 1 inch
(for example within 0.25 inches) of a third engine valve seat of
the plurality of engine valve seats. In certain embodiments, for
example, the at least one outlet may be positioned within 3 inches
(for example between 0.5 and 1.5 inches) of an orifice of an air
intake valve of at least one cylinder of the plurality of
cylinders, the at least a second outlet may be positioned within 3
inches (for example between 0.5 and 1.5 inches) of an orifice of an
air intake valve of at least a second cylinder of the plurality of
cylinders, and the at least a third outlet may be positioned within
3 inches (for example between 0.5 and 1.5 inches) of an orifice of
an air intake valve of at least a third cylinder of a plurality of
cylinders.
[0245] Certain embodiments may provide, for example, a second fuel
(for example an HHO gas) system for an internal combustion engine,
comprising: a pressure-resistant container, a multi-point gas
distribution system comprising a plurality of control valves to
distribute separate portions of the second fuel to multiple
locations about the internal combustion engine, and a multi-point
gas distribution control system that controls the plurality of
control valves to control the amount and timing of the delivery of
the second fuel to the multiple locations about the internal
combustion engine. In certain further embodiments, for example, the
pressure resistant container may comprise an electrolysis cell
configured to generate a second fuel from an electrolyte solution,
and a storage volume to hold a volume of the second fuel at a
pressure greater than 40 psia. In certain further embodiments, for
example, the at least one of the multiple locations may comprise at
least one air intake orifice. In certain further embodiments, for
example, the multi-point gas distribution control system may be
configured to deliver at least a portion of the second fuel in a
timed sequence based on an intake stroke timing of the at least one
air intake orifice. In certain further embodiments, for example, at
least a second one of the at least one of the multiple locations
may comprise at least one air intake orifice. In certain further
embodiments, for example, the multi-point gas distribution control
system may be further configured to deliver at least a second
portion of the second fuel in a timed sequence based on an intake
stroke timing of the at least one air intake orifice of the at
least second one of the at least one of the multiple locations. In
certain alternative embodiments, for example, the timed sequences
may be batched (i.e., the second fuel may be delivered to groups of
air intake orifices without regard to the timing of the air intake
stroke of any one particular air intake orifice). In certain
alternative embodiments, for example, the timing may be
simultaneous (i.e., the second fuel may be delivered to all air
intake orifices simultaneously). In certain embodiments, for
example, the multi-point gas distribution system may be configured
to provide an average of less than 15 liters, for example less than
10 liters, for example between 0.1 and 5 liters, or for example
between 0.1 and 2 liters (as measured at for example control
temperature and pressure or standard temperature and pressure) of
the second fuel per 120,000 crankshaft revolutions of the host
engine. In certain embodiments, for example, multi-point gas
distribution system may be configured to provide an average of less
than 15 liters, for example less than 10 liters, for example
between 0.1 and 5 liters, or for example between 0.1 and 2 liters
(as measured at for example control temperature and pressure or
standard temperature and pressure) of the second fuel per 120,000
crankshaft revolutions of the host engine per 100 hp average output
of the host engine. In certain embodiments, for example,
multi-point gas distribution system may be configured to provide an
average of less than 15 liters, for example less than 10 liters,
for example between 0.1 and 5 liters, or for example between 0.1
and 2 liters (as measured at for example control temperature and
pressure or standard temperature and pressure) of the second fuel
per 120,000 crankshaft revolutions of the host engine per 200 hp
average output of the host engine. In certain embodiments, for
example, multi-point gas distribution system may be configured to
provide an average of less than 15 liters, for example less than 10
liters, for example between 0.1 and 5 liters, or for example
between 0.1 and 2 liters (as measured at for example control
temperature and pressure or standard temperature and pressure) of
the second fuel per 120,000 crankshaft revolutions of the host
engine per 400 hp average output of the host engine. In certain
embodiments, for example, multi-point gas distribution system may
be configured to provide an average of less than 15 liters, for
example less than 10 liters, for example between 0.1 and 5 liters,
or for example between 0.1 and 2 liters (as measured at for example
control temperature and pressure or standard temperature and
pressure) of the second fuel per 120,000 crankshaft revolutions of
the host engine per 800 hp average output of the host engine. In
certain embodiments, for example, multi-point gas distribution
system may be configured to provide an average of less than 15
liters, for example less than 10 liters, for example between 0.1
and 5 liters, or for example between 0.1 and 2 liters (as measured
at for example control temperature and pressure or standard
temperature and pressure) of the second fuel per 120,000 crankshaft
revolutions of the host engine per 1400 hp average output of the
host engine. In certain embodiments, for example, multi-point gas
distribution system may be configured to provide an average of less
than 15 liters, for example less than 10 liters, for example
between 0.1 and 5 liters, or for example between 0.1 and 2 liters
(as measured at for example control temperature and pressure or
standard temperature and pressure) of the second fuel per 120,000
crankshaft revolutions of the host engine per 2000 hp average
output of the host engine.
[0246] In certain embodiments, for example, the method may comprise
introducing in the range of 1.25-30 liters (for example in the
range of 1.5-10 liters, in the range of 1.5-6 liters, in the range
of 2-5 liters, in the range of 2-3 liters, in the range of 3-4
liters, or in the range of 4-5 liters) of second fuel (for example
HHO gas) per hour per liter of displacement of the internal
combustion engine (for example in the range of 1.25-30 liters (for
example in the range of 1.5-10 liters, in the range of 1.5-6
liters, in the range of 2-5 liters, in the range of 2-3 liters, in
the range of 3-4 liters, or in the range of 4-5 liters) second fuel
(for example HHO gas) per hour per liter of displacement of the
internal combustion engine per 100 hp average output of the
internal combustion engine, in the range of 1.25-30 liters (for
example in the range of 1.5-10 liters, in the range of 1.5-6
liters, in the range of 2-5 liters, in the range of 2-3 liters, in
the range of 3-4 liters, or in the range of 4-5 liters) of second
fuel (for example HHO gas) per hour per liter of displacement of
the internal combustion engine per 200 hp average output of the
internal combustion engine, in the range of 1.25-30 liters (for
example in the range of 1.5-10 liters, in the range of 1.5-6
liters, in the range of 2-5 liters, in the range of 2-3 liters, in
the range of 3-4 liters, or in the range of 4-5 liters) of second
fuel (for example HHO gas) per hour per liter of displacement of
the internal combustion engine per 400 hp average output of the
internal combustion engine, in the range of 1.25-30 liters (for
example in the range of 1.5-10 liters, in the range of 1.5-6
liters, in the range of 2-5 liters, in the range of 2-3 liters, in
the range of 3-4 liters, or in the range of 4-5 liters) of second
fuel (for example HHO gas) per hour per liter of displacement of
the internal combustion engine per 800 hp average output of the
internal combustion engine, in the range of 1.25-30 liters (for
example in the range of 1.5-10 liters, in the range of 1.5-6
liters, in the range of 2-5 liters, in the range of 2-3 liters, in
the range of 3-4 liters, or in the range of 4-5 liters) of second
fuel (for example HHO gas) per hour per liter of displacement of
the internal combustion engine per 1400 hp average output of the
internal combustion engine, or in the range of 1.25-30 liters (for
example in the range of 1.5-10 liters, in the range of 1.5-6
liters, in the range of 2-5 liters, in the range of 2-3 liters, in
the range of 3-4 liters, or in the range of 4-5 liters) of second
fuel (for example HHO gas) per hour per liter of displacement of
the internal combustion engine per 2000 hp average output of the
internal combustion engine
[0247] Certain embodiments may provide, for example, a dual-chamber
vessel for use of an internal combustion engine, comprising: a
first chamber of the dual-chamber vessel configured for
electrolyzing an aqueous electrolyte solution, a port providing
liquid communication between the first chamber and a second chamber
of the dual-chamber vessel, the port comprising a liquid sealing
member, the liquid sealing member effective to maintain a liquid
seal of the first chamber under any orientation of the dual chamber
vessel. In certain embodiments, for example, the liquid sealing
member may comprise a flop tube. In certain embodiments, for
example, the liquid sealing member may be a rigid nozzle having an
outlet disposed in the second chamber. In certain embodiments, for
example, the rigid nozzle may have an outlet in the second chamber,
the outlet having a diameter D, and the outlet of the nozzle may be
positioned in aqueous electrolyte solution at a depth of at least
one diameter D from a top surface of the solution. In certain
further embodiments, for example, the volume of the aqueous
electrolyte solution is greater than half of the volume of the
second chamber and the nozzle extends at least half the length of
the chamber, allowing the outlet of the nozzle to maintain a liquid
seal under any orientation of the second chamber.
[0248] Certain embodiments may provide, for example, a gas
back-flow prevention element or system to prevent the HHO gas
collected in the upper chamber of the dual-chamber vessel from
passing to the lower chamber where the HHO generator cell is
positioned. In certain embodiments, for example, the dual-chamber
design may be equipped with a standpipe in the upper chamber to
allow HHO gas generated in the lower chamber to travel into the
upper chamber but prevent the HHO gas from back-flowing into the
lower chamber. The distal end of the standpipe may have an opening
for allowing the HHO gas received in the open end connected to the
divider, and in communication with the lower chamber, between the
upper and lower chambers to transfer into the upper chamber. The
opening in the distal end will be positioned proximate the center
point of the upper chamber, for example, the stand pipe may be
positioned in the center of the divider and extend perpendicularly
into the upper chamber (for example, vertically up into the upper
chamber) and terminate at the midpoint, for example the geometric
center, between the upper and lower surfaces defining the upper
chamber. In operation, the electrolyte level in the upper chamber
may be maintained above the opening in the distal end of the stand
pipe, for example it may be maintained at a minimum height equal to
the opening in the distal end plus the diameter of the opening in
the distal end (by way of example, if the upper chamber is 7 inches
tall and it is equipped with a 0.5 inch diameter stand pipe
positioned in the geometric center of the divider plate and
extending vertically upwardly to the geometric center of the upper
chamber, i.e., 3.5 inches upwardly, the electrolyte level will be
maintained at a height within the upper chamber of at least 4
inches (3.5 inches plus 0.5 inches). This should assure that the
electrolyte covers or seals the opening in the distal end of the
standpipe regardless of the orientation of the dual-chamber vessel
and therefore prevent back flow of HHO gas from the upper chamber
into the lower chamber, where the HHO generator cell is
positioned.
[0249] Certain embodiments may provide, for example, a retrofitted
internal combustion engine configured to use a second fuel (for
example an HHO gas) according to the second fuel system. In certain
embodiments, for example, the retrofitted internal combustion
engine may power a vehicle.
[0250] Certain embodiments may provide, for example, a system for
on-demand delivery of HHO gas for an internal combustion engine,
comprising: an electrolysis cell for generating the HHO gas, a
controller for determining an amount of the HHO gas sufficient to
reduce engine-out emissions to a pre-determined level, and an HHO
injection apparatus, in communication with the controller, for
delivering the HHO gas to at least one intake valve of the internal
combustion engine. In certain embodiments, one or more than one
(including for instance all) of the following embodiments may
comprise each of the other embodiments or parts thereof. In certain
embodiments, for example, the system may further comprise a
regulator for regulating a temperature and a pressure of the HHO
gas to be injected in the engine. In certain embodiments, for
example, the system may further comprise a knock sensor configured
to detecting engine knock and to send a signal to the controller to
adjust the HHO injection when engine knock is detected. In certain
embodiments, for example, the controller may at least partially
control the generation of the HHO gas. In certain embodiments, for
example, the system may further comprise an exhaust temperature
sensor connected to the controller. In certain embodiments, for
example, the controller may adjust the HHO injection when the
temperature of engine exhaust exceeds a pre-determined temperature
level. In certain embodiments, for example, the HHO gas may be
distributed individually to each intake valve of each cylinder via
a multi-point HHO gas injection (also called port gas injection or
MPI). In certain embodiments, for example, the multi-point
injection may inject gas into the intake ports just upstream of
each cylinder's intake valve, rather than at a central point within
an intake manifold. In certain embodiments, for example,
multi-point injection may be sequential, wherein injection of the
HHO gas may be timed to coincide with each cylinder's intake
stroke; batched, wherein HHO gas may be injected to the cylinders
in groups, without precise synchronization to any particular
cylinder's intake stroke; or simultaneous, wherein HHO gas may be
injected at the same time to all the cylinders. In certain
embodiments, for example, the multi-point injection may deliver the
HHO gas directly into the cylinder, i.e., direct injection.
[0251] In certain embodiments, for example, the HHO gas may be
delivered to the engine at a pressure in the range of 100-500 kPa
(for example in the range of 100-400 kPa, or in the range of 40-60
psig or 45-55 psig). In certain embodiments, for example, the HHO
gas may be delivered to the engine at temperature in the range of
35-120.degree. C. (for example at a temperature in the range of
35-75.degree. C.). In certain embodiments, for example, the HHO gas
may be delivered to the intake port of at least one cylinder of the
engine at a temperature in the range of 100-130.degree. F. In
certain embodiments, for example, the HHO gas may be delivered to
the intake port of at least one cylinder of the engine at a
pressure in the range of 100-500 kPa. In certain embodiments, for
example, the controller may further control the volume of HHO gas
injected based, at least in part on the engine demand, load, fuel
consumption, and/or airflow. In certain embodiments, for example, a
timing and duration of at least one HHO gas injector may be
controlled at least in part based on the engine demand.
[0252] In certain embodiments, for example, the system may further
comprise an HHO temperature sensor connected to the controller. In
certain further embodiments, for example, the controller may adjust
the HHO injection when the temperature of the HHO gas is outside a
pre-determined temperature range. In certain embodiments, for
example, the system may further comprise an HHO pressure sensor
connected to the controller. In certain embodiments, for example,
the controller may adjust the HHO injection when the pressure of
the HHO gas exceeds a pre-determined pressure level. In certain
embodiments, for example, the controller may comprise an anti-surge
protector. In certain embodiments, for example, the controller may
comprise a processor configured to calculate an amount of the HHO
gas sufficient to reduce engine-out emissions to a pre-determined
level based on engine operating parameters. In certain embodiments,
for example, the controller may comprise a seal to prevent water
intrusion.
[0253] In certain embodiments, for example, the electrolysis cell
may include any of the electrolysis cell embodiments disclosed
herein. In certain embodiments, for example, the electrolysis cell
may comprise a pressure-resistant container comprising a first
defined space for holding an electrolyte solution, a plurality of
electrolysis plates retained within the first defined space, and a
second defined space for holding a gas, wherein a volume of the
second defined space may be greater than the volume of the first
defined space. In certain embodiments, for example, the
pressure-resistant container may further comprise a positive
terminal, a negative terminal, a gas outlet, an electrolyte
solution fill port and/or a drain port. In certain embodiments, for
example, the electrolysis cell may further comprise a heat
exchanger in communication with, integral to, or connected to the
gas outlet.
[0254] Certain embodiments may provide, for example, a system for
onboard, on-demand delivery of an HHO gas for an internal
combustion engine (for example for a vehicle), comprising: an
electrolysis cell configured to produce a required amount of HHO
gas; and an HHO gas delivery system configured to deliver the HHO
gas to the internal combustion engine. In certain embodiments, for
example, delivery of the required amount of HHO gas may comprise
delivering a portion of the required amount of HHO gas from the
electrolysis cell to a position proximate an orifice (for example
within 3 inches of the at least one orifice) of a combustion
chamber intake valve, wherein said portion of the HHO gas does not
contact combustion intake air until said portion reaches said
position. In certain embodiments, for example, the HHO gas delivery
system may deliver the portion of the HHO gas without causing any
noticeable change in its chemical and/or performance properties to
said position about the combustion chamber intake valve. In certain
embodiments, for example, the internal combustion engine may
provide power to a vehicle and the required amount of HHO gas may
be generated by electrolyzing in the range of 4-16 ounces of water
per 10,000 miles traveled by the host vehicle or in the range of
4-16 ounces of water per 20,000,000 crankshaft revolutions of the
host engine. In certain embodiments, for example, the internal
combustion engine may provide power to a vehicle and the required
amount of HHO gas may be in the range of 300-1000 liters per 10,000
miles or per 20,000,000 crankshaft revolutions, based on a gas
measured at a temperature of 25.degree. C. and pressure of 1
atmosphere. In certain embodiments, for example, the HHO gas
required may be in catalytic quantities.
[0255] In certain embodiments, for example, the required amount of
HHO gas may be, on average, in the range of 1-10 liters per hour or
per 120,000 crankshaft rotations, based on a gas temperature of
25.degree. C. and pressure of 1 atmosphere. In certain embodiments,
for example, the required amount of HHO gas may be in the range of,
on average, 1-10 liters per hour or per 120,000 crankshaft
rotations, based on a gas temperature of within 20.degree. C. of
the temperature of engine coolant and a pressure of in the range of
40-50 psia. In certain embodiments, for example, the internal
combustion engine may be a 15-liter diesel engine for a freight
vehicle. In certain further embodiments, for example, the required
amount of HHO gas may be in the range of, on average, 5-30 liters
per hour or per 120,000 crankshaft rotations, based on a gas
temperature of within 20.degree. C. of the temperature of engine
coolant and a pressure of in the range of 40-50 psia. In certain
embodiments, for example, a doubling of the engine volume (for
example from a 3-liter engine to a 6-liter engine) may increase the
required amount of HHO gas by in the range of 5-15% (for example by
approximately 10%). In certain embodiments, for example, the system
may further comprise an HHO gas storage system configured to store
an excess amount of HHO gas for at least 1 week (for example at
least 1 months). In certain embodiments, for example, the required
amount of HHO gas may be at least 1 liter of HHO (for example at
least 1.5 liters) gas per each liter of engine displacement for
every 120,000 crankshaft revolutions of the engine at a pressure of
at least 100 kPa relative to the air intake pressure of a
combustion chamber of the engine. In certain embodiments, for
example, the electrolysis cell may be configured to store a volume
of HHO gas sufficient to deliver the required amount of HHO gas for
at least 120,000 crankshaft revolutions of the engine. In certain
embodiments, for example, the electrolysis cell may be configured
to generate the required amount of HHO gas for extended operation
of the internal combustion engine, wherein the temperature of the
electrolysis cell does not exceed 80.degree. C. (for example, does
not exceed 65.degree. C.). In certain embodiments, for example, the
electrolysis cell may be powered by an 11-14 VDC power source. In
certain further embodiments, for example, the electrolysis cell may
comprise an electrolyte solution, wherein the concentration of one
or more electrolytes present in the electrolyte solution may be
selected, maintained, and/or adjusted to provide a current draw of
less than 20 amps (for example less than 10 amps) at the operating
voltage and temperature of the electrolysis cell. In certain
embodiments, for example, the average (or maximum) current draw may
be less than 20 amps, for example less than 15 amps, less than 12
amps, less than 10 amps, less than 5 amps, or the current draw may
be less than 2 amps. In certain embodiments, for example, the
current draw may be in the range of 5 to 20 amps, for example in
the range of 7 to 15 amps, in the range of 8 to 12 amps, or the
average (or maximum) current draw may be in the range of 9 to 11
amps. In certain embodiments, for example, the average (or maximum)
current applied per square centimeter of electrolysis plate area of
the electrolysis plates in the electrolysis cell (i.e., the current
density) may be less than 500 mA/cm.sup.2, less than 250
mA/cm.sup.2, less than 100 mA/cm.sup.2, less than 80 mA/cm.sup.2,
less than 75 mA/cm.sup.2, less than 60 mA/cm.sup.2, less than 50
mA/cm.sup.2, less than 40 mA/cm.sup.2, less than 30 mA/cm.sup.2,
less than 20 mA/cm.sup.2, or the current applied per square
centimeter of electrolysis plate area of the electrolysis plates in
the electrolysis cell may be less than 10 mA/cm.sup.2.
[0256] In certain embodiments, for example, the current applied per
square centimeter of electrolysis plate area of the electrolysis
plates in the electrolysis cell (i.e., the current density) may be
in the range of 10 to 500 mA/cm.sup.2, in the range of 100 to 250
mA/cm.sup.2, for example in the range of 25 to 150 mA/cm.sup.2, in
the range of 25 to 100 mA/cm.sup.2, in the range of 25 to 75
mA/cm.sup.2, in the range of 40 to 60 mA/cm.sup.2, or the current
applied per square centimeter of electrolysis plate area of the
electrolysis plates in the electrolysis cell may be in the range of
50 to 75 mA/cm.sup.2.
[0257] In certain embodiments, for example, electrolysis cell
plates may be made of stainless steel or titanium. In certain
embodiments, for example, electrolysis cell plates may be coated
with platinum or iridium. In certain embodiments, for example,
electric current draw may increase when electrolyte solution heats
up, for example, average (or maximum) electric current draw may
increase from 5-15 Amps to 15-35 Amps, or from 10-11 Amps to 20-29
Amps. In certain embodiments, for example, one of the foregoing
coatings may render the electric draw less sensitive to

[0258] In certain further embodiments, for example, the electrolyte
concentration may be lower than the concentration of electrolyte in
a conventional electrolysis cell. In certain embodiments, for
example, the electrolyte solution may be exclusive of sulfuric
acid. In certain embodiments, for example, the electrolysis cell
may be operated continuously (for example without pulsed width
modulation) for a period of time (for example at least 10 minutes,
at least 30 minutes, at least 1 hour, or indefinitely) without
overheating, for example without heating to a temperature in excess
of 65.degree. C. In certain further embodiments, for example, an
ability to operate the electrolysis cell continuously without
overheating may be due at least in part to a low electrolyte
concentration in the electrolyte solution (for example less than 2
vol. % of electrolyte, such as less than 0.5 vol. % of electrolyte)
and/or an average (or maximum) current draw of less than 15 amps
(for example less than 10 amps). In certain embodiments, for
example, the electrolysis cell may be powered by a 20-28 VDC power
source. In certain further embodiments, for example, the
concentration of the one or more electrolytes may be selected,
maintained, and/or adjusted to provide an average (or maximum)
current draw of less than 10 amps at the operating temperature (for
example an operating temperature of less than 80.degree. C.) of the
electrolysis cell. In certain embodiments, for example, the
electrolysis cell may be configured to operate on less than 250
watts of DC power. In certain embodiments, for example, the
electrolysis cell may be configured to have less than 3 ohm of
resistance.

the average peak demand for a specified period of time) for the
vehicle. In certain embodiments, one or more than one (including
for instance all) of the following embodiments may comprise each of
the other embodiments or parts thereof.
[0268] In certain embodiments, for example, the gas storage portion
may have a fixed volume. In certain embodiments, for example, the

example for less than 20 minutes before pausing). In certain
embodiments, for example, HHO gas generation may be for less than
12 minutes per hour or per 120,000 crankshaft rotations. In certain
embodiments, for example, HHO gas generation may be regulated to

limits, for example 2002, 2004, 2007, 2010, 2014 Environmental
Protection Agency emission limits and/or Euro I, Euro II, Euro III,
and or Euro VI emission limits].

[0277] Certain embodiments may provide, for example, apparatus,
methods, or systems to improve the performance of an internal
combustion engine. In certain embodiments, one or more than one
(including for instance all) of the following embodiments may
comprise each of the other embodiments or parts thereof. Certain
embodiments may provide, for example, apparatus, methods, or
systems to improve the fuel economy of an internal combustion
engine. Certain embodiments may provide, for example, apparatus,

a marine engine, or a 2-stroke engine). In certain embodiments, for
example, internal combustion engines may realize a fuel economy
increase of at least 1% (for example at least 2%, at least 5%, or
at least 20%).
[0280] Certain embodiments may provide, for example, apparatus,
methods, or systems to achieve substantially complete combustion,
or at least more complete combustion, within the internal
combustion engine (for example greater combustion of at least more
than 10%, for example more than 20%).
[0281] Certain embodiments may provide, for example, apparatus,
methods, or systems to improve the operation of the internal
combustion engine. In certain embodiments, one or more than one
(including for instance all) of the following embodiments may
comprise each of the other embodiments or parts thereof. In certain
embodiments, for example, the internal combustion engine may
operate at a cooler temperature and/or may run cleaner. In certain
embodiments, for example, the internal combustion engine may
generate more power or more consistent or even power output for the
same or lower amount of fuel. In certain embodiments, for example,
the internal combustion engine may generate exhaust temperatures
more suitable for efficient operation of exhaust aftertreatment
systems. In certain embodiments, for example, the internal
combustion engine may generate exhaust temperatures more suitable
for efficient operation of diesel particulate filter (DPF). In
certain embodiments, for example, the internal combustion engine
may generate exhaust temperatures more suitable for efficient
operation of selective catalytic reactor (SCR). In certain
embodiments, for example, the internal combustion engine may
generate exhaust temperatures more suitable for efficient operation
of diesel oxidation catalyst (DOC). In certain embodiments, for
example, the internal combustion engine may generate exhaust
temperatures more suitable for efficient operation of NOx trap. In
certain embodiments, for example, the exhaust temperature of the
combustion engine may be reduced by at least 10.degree. F. relative
due to introduction of an ultra low quantity of HHO gas according
to the methods, systems, and apparatus described herein, for
example by at least 10.degree. F., by at least 20.degree. F., by at
least 30.degree. F., by at least 40.degree. F., by at least
50.degree. F., by at least 60.degree. F., by at least 70.degree.
F., by at least 70.degree. F., by at least 80.degree. F., by at
least 90.degree. F., or the exhaust temperature may be reduced by
at least 100.degree. F. In certain embodiments, for example, the
exhaust temperature of the combustion engine may be reduced by in
the range of 5 to 125.degree. F., for example in the range of in
the range of 5 to 125.degree. F., in the range of 10 to 100.degree.
F., in the range of 25 to 100.degree. F., in the range of 50 to
100.degree. F., in the range of 70 to 95.degree. F., in the range
of 10 to 40.degree. F., in the range of 10 to 30.degree. F., or the
exhaust temperature may be reduced by in the range of 75 to
85.degree. F.
[0282] In certain internal combustion engine applications (for
example heavy duty, over-the-road diesel trucks) the exhaust may be
equipped with an aftertreatment system to address environmental
regulations. The system often consists of diesel particulate
filters, for example, wall-flow diesel particulate filters (DPFs)
to remove or trap particular from within the passing exhaust
stream. These DPF's are regenerated by burning off the accumulated
particulate in a process called regeneration. Diesel particulate
matter burns when exposed to temperatures above 600 degrees
Celsius. A typical DPF burner employs diesel fuel as an energy
source. Diesel fuel may be injected into the evaporator portion of
the burner, where it is atomized and then provided to the
combustor. There, combustion of atomized fuel releases heat, which
may be transferred through a heat transfer element to the engine
exhaust, raising its temperature to the level sufficient to burn
off accumulated material trapped by the DPF. This regeneration
combustion may be assisted by the introduction of HHO. In certain
embodiments, for example, HHO may be introduced on a controlled
basis to aid the regeneration combustion. In certain embodiments,
for example, this may be accomplished by positioning an HHO
injector proximate the combustion site as a second fuel for the
regeneration combustion. In certain embodiments, for example, this
injector may deliver stored HHO, stored hydrogen or be fed HHO from
an on-board HHO generator. In certain embodiments, for example, the
engine may be equipped with a HHO generator and a series of HHO
injectors to distribute HHO about the intake ports of the engine
and a further injector to distribute HHO proximate the combustion
site of the DPF regeneration burner to aid as a second fuel for the
regeneration combustion.
[0283] Certain embodiments may provide, for example, apparatus,
methods, or systems to introduce a second fuel (for example a
second fuel exclusive of a petroleum-derived fuel) into an internal
combustion engine. In certain embodiments, for example, the second
fuel (also referred to as booster gas or enhancement gas or HHO gas
throughout this application, unless specifically defined otherwise)
may comprise hydrogen, oxygen and/or mixtures thereof derived from
electrolysis of an aqueous electrolyte solution comprising ions,
for example an electrolysis solution. In certain embodiments, for
example, the second fuel may substantially comprise hydrogen,
oxygen and/or mixtures thereof. In certain embodiments, for
example, the second fuel may predominantly comprise hydrogen,
oxygen and/or mixtures thereof. In certain embodiments, for
example, the second fuel may be a product of electrolysis. In
certain embodiments, for example, the second fuel or components of
the second fuel, for example hydrogen may benefit the combustion
reaction by serving as a catalyst.
[0284] Certain embodiments may provide, for example, apparatus,
methods, or systems to produce an oxygen-hydrogen gas mixture (for
example an oxygen-hydrogen gas mixture for use as a second fuel in
an internal combustion engine). In certain embodiments, for
example, the gas mixture may be an oxygen-rich or hydrogen-rich a
gas mixture. In certain embodiments, for example, the gas mixture
may comprise one or more of aqueous electrolyte solution
electrolysis components (for example monatomic oxygen and/or
monatomic hydrogen).
[0285] Certain embodiments may provide, for example, apparatus,
methods, or systems to produce a gas mixture that is approximately
two parts hydrogen to one part oxygen (for example 2:1) or less
than 2:1 (for example 1.75:1, 1.5:1, 1.25:1, 1:1, 0.75:1, or
0.5:1). In certain embodiments, for example, the gas mixture
produced may be modified before being delivered to the internal
combustion engine. In certain embodiments, for example, the gas
mixture may be combined with an additive and/or the composition of
the gas mixture may be modified by adding, recycling or removing
portions of the gas mixture. In certain embodiments, for example,
an apparatus, method, or system may generate hydrogen and oxygen at
a hydrogen to oxygen ratio of 2:1, but some of the hydrogen or
oxygen, for example oxygen, may be trapped in bubbles, and the
apparatus, method, or system may be configured to release the
trapped oxygen to effectively deliver more oxygen to the internal
combustion engine.
[0286] Certain embodiments may provide, for example, apparatus,
methods, or systems to result in a more reliably controlled gas
mixture generation process. In certain embodiments, for example,
the current provided to the system for gas generation may be
continually or continuously regulated or controlled, for example,
in real time (or substantially real time), so as to provide
predetermined or controlled quantity of gas, for example, in
relation to the engine speed and/or demand.
[0287] Certain embodiments may provide, for example, apparatus,
methods, or systems to utilize a substantially closed-loop system
that recycles a water-reagent (or water-electrolyte or aqueous
electrolyte solution electrolysis component) mixture to reduce its
consumption.
[0288] Certain embodiments may provide, for example, apparatus,
methods, or systems to alter combustion (for example diesel
combustion) chemistry to reduce particulate formation, for example
reduce particulate formation by greater than 5% (for example
greater than 10%).
[0289] Certain embodiments may provide, for example, apparatus,
methods, or systems to increase the concentration of an oxidizer in
an internal combustion engine, for example increase the amount of

[0290] Certain embodiments may provide, for example, apparatus,
methods, or systems that serve as a mechanism for distributing the
oxidizer for more even air/fuel mixture.
[0291] Certain embodiments may provide, for example, apparatus,
methods, or systems to generate a gas mixture that is an accelerant
to speed combustion, enhance combustion, and/or increase the extent
of combustion.

production apparatus 604 and a central processing unit (CPU) 606.
The CPU 606 receives power through an ignition switch controlled
line 608. The CPU 606 provides a control signal through a control
signal line 610 to a power relay 612 to regulate power to the
apparatus 604. HHO gas exits the apparatus 604 through an HHO gas
outlet tubing 614 and is passed through the regulator 616 and
cooled with engine coolant circulated through engine coolant lines
618(A&B). Cooled HHO gas is then transmitted through a pressure
regulated tubing 620 to an HHO gas injector manifold 622. The HHO
gas injector manifold 622 distributes portions of the HHO gas
through the set of injectors fitted with injector lances 624A,
624B, 624C, and 624D.
[0335] FIG. 7 is a partial cross-sectional view of an intake port

[0338] In certain embodiments, for example, the dual-chamber HHO
gas production apparatus may comprise an electrolysis cell having 3
to 10 electrolysis cell plates, for example 5 cell plates. In
certain embodiments, for example, each cell plate may be between 20
sq.in. to 30 sq.in. in area, for example 24 sq.in. In certain
embodiments, for example, each cell plate may be 4'' by 6'' in
size. In certain embodiments, for example, a housing (a plate
holder) may hold the cell plates. In certain embodiments, for
example, the housing may be made of a plastic material, for example
of nylon 66. In certain embodiments, for example, nylon material
may completely surround the cell plates, for example cell plates
may be completely enclosed.
[0339] In certain embodiments, for example, the electrolysis cell
may have holes for aqueous electrolyte solution ingress. In certain
embodiments, for example, the HHO gas production apparatus may have
3 to 10 holes, for example 4 holes, or 6 holes. In certain
embodiments, for example, each hole may be 0.2'' to 1'' in
diameter, for example 0.5'' in diameter.
[0340] In certain embodiments, for example, there may be an O-ring
seal in a flange of an electrolysis cell. In certain embodiments,
for example, the O-ring may be made of elastic material, for
example Delrin 400 or a generic acetal.
[0341] In certain embodiments, for example, generated HHO gas
bubbles may be collected into an orifice extending into a nozzle in
the upper chamber of the dual-chamber HHO gas production apparatus.
In certain embodiments, for example, the nozzle may be made of
corrosion resistant material, for example of stainless steel. In
certain embodiments, for example, the nozzle may be designed to
direct bubbles into the upper chamber. In certain embodiments, for
example, the nozzle may remain below the aqueous electrolyte
solution line during operation. In certain embodiments, for
example, contact between HHO gas and plate surface (for example
contact with platinum coated on the plates) may be avoided. In
certain embodiments, for example, aqueous electrolyte solution may
flow back down through the nozzle.
[0342] In certain embodiments, for example, electrolyte may be
added every 3 to 10 months of operation, for example every 6 months
of operation. In certain embodiments, for example, electrolyte may
be added every 5,000 to 20,000 miles during on-road operation, for
example every 10,000 miles.
[0343] In certain embodiments, for example, the dual-chamber HHO
gas production apparatus may hold electric charge for a long time
after shut-off, for example for up to 2 hours after shut-off. In
recognition of presence of hydrogen in the HHO gas, in certain
embodiments, for example, the dual-chamber HHO gas production
apparatus is designed to mitigate damages resulting from any fast
pressure rise event, for example from an explosion. In certain
embodiments, for example, the system may be equipped with a
fool-proof check valve, for example the entire dual-chamber HHO gas
production apparatus may cooperate to provide a, minimally
destructive, or non-destructive controlled pressure relief
system.
[0344] In certain embodiments, for example, O-rings in upper and
lower chambers and elongated retaining members may be part of the
minimally destructive, non-destructive, controlled pressure-relief
system. In certain embodiments, for example, one or more of the
elongated retaining members (for example, tie rods) may be yielding
elongated members, for example one, or two, or all tie rods may be
yielding elongated members. In certain embodiments, for example,
the yielding elongated members may yield and/or stretch by a large
amount, for example by at least 3/16 of an inch if HHO gas pressure
rises quickly (for example to a pressure of 1500 psig or more). In
certain embodiments, for example, the yielding elongated members
may yield and/or stretch by at least 1/4 inch, for example at least
1/2 inch, at least 3/4 inch, at least 1 inch, at least 2 inches, or
the yielding elongated members may stretch by at least 2.5 inches.
In certain embodiments, for example, the yielding elongated members
may stretch by less than 3 inches, for example less than 2 inches,
less than 1 inch, less than 3/4 inch, less than 1/2 inch, or the
yielding elongated members may stretch by less than 1/4 inch. In
certain embodiments, for example, stretching of the yielding
elongated members may create an opening with an area of 2 to 10 sq.
inches, for example an area of 2 to 5 sq. inches or 5-10 square
inches. In certain embodiments, for example, there may be 2 to 10
yielding elongated members, for example six yielding elongated
members. In certain embodiments, for example, the yielding
elongated members may be made of steel, for example of 316L
stainless steel. In certain embodiments, for example, pressure
relief may occur during a period in the range of 0.05 to 2
milliseconds to relieve pressure, for example in the range of 0.05
to 0.075 milliseconds, in the range of 0.075 to 0.1 milliseconds,
in the range of 0.1 to 0.25 milliseconds, in the range of 0.25 to 1
milliseconds, or pressure relief may occur during a period of 1 to
2 milliseconds.
[0345] In certain embodiments, for example, the yielding elongated
members may be forged metal rods with a thread cut into them. In
certain embodiments, for example, the thread may be applied along
the full length the yielding elongated members. In certain
embodiments, for example, the yielding elongated members may be
designed to avoid stress risers, for example designed to ensure
that the yielding elongated members stretch uniformly. In certain
embodiments, for example, the yielding elongated members may be
equipped with a washer and a nyloc nut on each end. In certain
embodiments, for example, nyloc nuts may be made of stainless
steel. In certain embodiments, for example, the yielding elongated
members may be assembled with 50 to 100 lb-in of torque, for
example 75 lb-in of torque. In certain embodiments, for example, a
lubricant may be used on the threads to achieve the correct
torque.
[0346] In certain embodiments, for example, the upper chamber and
the lower chamber may be in fluid communication with each other. In
certain embodiments, for example, an ignition source may be in the
lower chamber. In certain embodiments, for example, the
dual-chamber HHO gas production apparatus may be designed so that
no components leave the HHO gas production system during a fast
pressure rise. In certain embodiments, for example, the
dual-chamber HHO gas production apparatus may be designed so that
the weakest links in the system are the yielding elongated members,
for example all other components are tougher that the yielding
elongated members. In certain embodiments, for example, the HHO gas
production system may be designed to accommodate HHO gas pressure
of up to 2000 psig, up to 1500 psig, up to 1000 psig, up to 500
psig, or up to 300 psig.
[0347] In certain embodiments, for example, the vessel may be used
for carrying other liquids and/or munitions besides aqueous
electrolyte solution for electrolysis.
[0348] In certain embodiments, for example, the system may be
scalable. In certain embodiments, for example, the system may be
scaled up by increasing a number of the yielding elongated members.
In certain embodiments, for example, the system may be scaled up by
increasing diameter of the yielding elongated members.
[0349] In certain embodiments, for example, the top plate may be
0.2 to 1 inch think, for example 3/8 of an inch thick. In certain
embodiments, for example, the top plate may be made of steel, for
example of 304 stainless steel. In certain embodiments, for
example, the top plate may be made of the same material as the side
wall of the electrolysis cell. In certain embodiments, for example,
the HHO gas production system may be equipped with one or more
O-rings to seal top plate above the side wall. In certain
embodiments, for example, there may be a ball valve in the center
of the top plate.
[0350] In certain embodiments, for example, the middle plate may be
dished at an angle to enhance collection of the HHO gas.
[0351] In certain embodiments, for example, the HHO gas production
system may have a float switch. In certain embodiments, for
example, the float switch may open when orientation of the HHO gas
production system deviates from vertical by a large amount, for
example by 5.degree. off the vertical, or by 10.degree. off the
vertical, or by 20.degree. off the vertical, by 30.degree. off the
vertical, or by 45.degree. off the vertical or in a range of
between 10.degree. to 45.degree. off the vertical, for example, in
a range of between 10.degree. to 25.degree. off the vertical. In
certain embodiments, for example, the float switch may operate like
a Hall Effect switch. In certain embodiments, for example, the
float switch may have wires attached to it, for example three
wires. In certain embodiments, for example, the wires may include
one voltage in wire, and two voltage out wires (i.e., wires for
thermal and float). In certain embodiments, for example, an
anti-slosh device may hold the float. In certain embodiments, for
example, the float switch may be guided by a centering rod.
[0352] In certain embodiments, for example, the HHO gas production
system may be equipped with a controller. In certain embodiments,
for example, the controller may have a touchscreen display. In
certain embodiments, for example, the controller may have 100 to
1000 wire plugs, for example 237 wire plugs. In certain
embodiments, for example, the controller may be able to communicate
with the engine control module (ECM). In certain embodiments, for
example, the controller may use OEM sensors, for example a flywheel
based OEM sensor for rpm measurement.
[0353] In certain embodiments, for example, the HHO gas production
system may generate very little power drop on the ECM side (for
example the ECM may not notice a presence of the system). In
certain embodiments, for example, the controller may connect
directly to the OEM sensors. In certain embodiments, for example,
sensors may include a fuel injector sensor, an rpm (crank) sensor,
and MAP (manifold air pressure) sensor.
[0354] In certain embodiments, for example, the HHO gas production
system may be used as a retrofit device. In certain embodiments,
for example, the HHO gas production system may have fuel maps. In
certain embodiments, for example, the HHO gas production system
optionally may connect to the ECM. In certain embodiments, for
example, the HHO gas production system may not require modification
of factory computer software. In certain embodiments, for example,
the HHO gas production system may be designed to inject only a
small amount of HHO gas into an engine, for example so small that
the ECM does not notice system's presence. In certain embodiments,
for example, a limit for amount of HHO gas injection may be 10% to
30% of HHO gas, for example 18% of HHO gas, or 26% of HHO gas.
[0355] FIG. 10 schematically depicts a combustion cycle within a
combustion chamber 1000 of a representative cylinder of a
four-stroke internal combustion engine. At the start of the cycle,
the piston 1004 is at approximately Top Dead Center of a crankshaft
rotation, and compressed fuel ignites in the presence of HHO gas
and expands in a power stroke to drive the piston 1004 downward
until the crankshaft rotates through 180.degree. and brings the
piston to Bottom Dead Center as shown. At the bottom of the power
stroke, the exhaust valve opens and the upward stroke of the piston
1004 drives the exhausted fuel out of the combustion chamber 1000,
bringing the crankshaft to a rotation of 360.degree.. During the
intake stroke, the piston moves downward and the crankshaft rotates
from 360.degree. to 540.degree., drawing a fresh charge of air
through an air intake valve 1002. During a 1-3 ms portion of the
intake stroke when the crankshaft rotates through a stroke range of
between 360.degree. to 400.degree. 1006, HHO gas is injected with
the fresh charge of air. The HHO gas injection may be continuous
over the stroke range or may be pulsed. The 1-3 ms portion of the
intake stroke may be in the range of 1-1.5 ms, 1.5-2 ms, or 2-3
ms). Once the intake stroke is completed, the HHO gas and air are
compressed until the crankshaft rotates through 720.degree.,
followed by a new power cycle.
[0356] While FIG. 10 describes an embodiment of the invention,
other variations fall within scope of the disclosure. In certain
embodiments, for example, HHO gas may be injected when the
crankshaft rotates through a stroke range of between 360.degree. to
540.degree., for example between 360.degree. to 500.degree.,
between 360.degree. to 450.degree., between 360.degree. to
425.degree., between 360.degree. to 395.degree., between
360.degree. to 390.degree., between 360.degree. to 380.degree.,
between 365.degree. to 500.degree., between 365.degree. to
450.degree., between 365.degree. to 425.degree., between
365.degree. to 395.degree., between 365.degree. to 390.degree.,
between 365.degree. to 380.degree., between 380.degree. to
500.degree., between 380.degree. to 450.degree., between
380.degree. to 425.degree., between 380.degree. to 395.degree.,
between 380.degree. to 390.degree., between 400.degree. to
500.degree., between 400.degree. to 450.degree., or between
400.degree. to 425.degree., between 425.degree. to 500.degree.,
between 425.degree. to 450.degree., or HHO gas may be injected when
the crankshaft rotates through a stroke range of between
450.degree. to 500.degree.. In certain embodiments, for example,
the HHO gas injection may be continuous throughout the stroke
range. In certain embodiments, for example, the HHO gas injection
may be pulsed throughout the stroke range.
[0357] In certain embodiments, for example, HHO gas injectors may
have metal tubes, for example copper tubes, to carry HHO gas to the
engine. In certain embodiments, for example, the ends of tubes may
be soldered shut. In certain embodiments, for example, an orifice
may be drilled in the soldered end of the tube. In certain
embodiments, for example, the orifice diameter may be 10 to 50
thousands of an inch in diameter (for example 16 thousands of an
inch in diameter).
[0358] In certain embodiments, for example, HHO gas injectors may
be connected in a daisy chain on the power side. In certain
embodiments, for example, HHO gas injectors may take 1 to 20
milliamps of electric current, for example 5 milliamps of electric
current. In certain embodiments, for example, the power may be
turned on for 1 to 3 milliseconds every engine cylinder cycle, for
example for 1.35 milliseconds. In certain embodiments, for example,
HHO gas injection may be timed with respect to the engine intake
valve opening.
[0359] In certain embodiments, for example, copper tubes may be
passed through the wall of the intake manifold. In certain
embodiments, for example, copper tubes may be free floating inside
the intake manifold. In certain embodiments, for example, one or
more openings may be drilled in an intake manifold or in a valve
cover of the engine, for example to assist with an installation of
the tubes. In certain embodiments, for example, each opening may be
5 to 50 mm in diameter, for example 10 mm in diameter.
[0360] FIGS. 11(A-C) schematically depict a cylindrical dual
chamber vessel in various orientations, the dual chamber vessel
having a rollover abatement system. FIG. 11A depicts the vessel
1100 in an upright orientation. A lower chamber 1102 is completely
filled with electrolyte and has electrolysis plates 1104 with power
connectors 1122A and 1122B disposed therein. The lower chamber 1102
and an upper chamber 1106 are separated by a middle plate 1108, the
middle plate 1108 defining an orifice 1110 though which electrolyte
and HHO gas may be communicated between the chambers. The upper
chamber 1106 is filled with electrolyte up to a predetermined level
above the middle plate 1108, and at the predetermined level the
electrolyte defines a free surface 1112 that contacts HHO gas in a
vapor space 1114 above the electrolyte. HHO gas is released from
the vapor space 1114 under controlled conditions through an outlet
1116 equipped with a check valve 1118. The middle plate 1108 is
equipped with a rollover abatement nozzle 1120 configured to
provide a liquid seal to the lower chamber 1102 under any
orientation of the dual chamber vessel 1100, provided that the
predetermined level of electrolyte in the upper chamber 1106 is
maintained at a minimum height above the nozzle 1120 in the upright
orientation as described further herein. FIG. 11B shows the vessel
1100 tilted at an approximately 45.degree. angle to the right. As
shown, the free surface 1112 remains above a distal end of the
nozzle 1120, and the lower chamber remains under liquid seal. FIG.
11C shows the vessel 1100 fully inverted. As shown, the distal end
of the nozzle 1120 now penetrates the free surface 1112, thereby
maintaining a liquid seal of the lower chamber. Of note, the
electrolysis plates 1104 are immersed in electrolyte and isolated
from the HHO gas, which HHO gas is retained in the upper chamber
1106 above the free surface 1112 as shown.

%, in the range of 1.5-3 vol. %, in the range of 0.1-1 vol. %, in
the range of 0.1-0.5 vol. %, in the range of 0.2-0.4 vol. %, or the
electrolyte solution may comprise an aqueous electrolyte solution
with a concentration of electrolyte in the range of 0.25-0.35 vol.
% (in total) relative to the total volume of the aqueous

wt. %, for example in the range of 0.5-3 wt. %, in the range of
1.5-3 wt. %, in the range of 0.1-1 wt. %, in the range of 0.1-0.5
wt. %, in the range of 0.2-0.4 wt. %, or the aqueous electrolyte

temperature of the electrolysis cell. In certain further
embodiments, for example, the electrolyte concentration may be
lower than the concentration of electrolyte a conventional

electrolyte solution may be exclusive of sulfuric acid. In certain
embodiments, for example, the electrolysis cell may be operated
continuously (for example without pulsed width modulation) for a
period of time (for example at least 10 minutes, at least 30
minutes, at least 1 hour, or indefinitely) without overheating, for
example without heating to a temperature in excess of 65.degree. C.
In certain further embodiments, for example, an ability to operate
the electrolysis cell continuously without overheating may be due
at least in part to a low electrolyte concentration in the aqueous
electrolyte solution and/or a current draw of less than 15 amps
(for example less than 10 amps). In certain embodiments, for
example, the aqueous electrolyte solution may comprise a low
quantity of potassium carbonate (for example 0.3 wt. % potassium
carbonate) and have a pH in the range of 7-8.
[0377] In certain embodiments, for example, the electrolysis cell
may further comprise a plurality of electrolysis plates. In certain
further embodiments, for example, the plurality of electrolysis

of plates, for example a first one of the plurality of electrolysis
plates may be disposed at a distance in the range of 0.5-3 mm from
a second adjacent one of the plurality of plates.
[0380] In certain embodiments, for example, the plates may comprise
(for example be composed of or be partially or completely coated
with) a material that is composed of or comprises a highly
conductive and low corrosivity material, for example a material
with a higher conductivity higher than 304 stainless steel and a
corrosivity in the electrolyte environment of about the same or
less than 304 stainless steel. In certain embodiments, for example,
at least a portion of at least one surface of at least one of the
plurality of electrolysis plates may comprise platinum, titanium,
iridium, brass, gold, nickel alloy, silver, graphene or a
combination of one or more thereof. In certain embodiments, for
example, at least one of the electrode plates (for example all of
the electrode plates) may comprise a first material coated on a
second material. In certain embodiments, for example, the first
material may comprise platinum, titanium, iridium, brass, gold,
nickel alloy, silver, steel (for example stainless steel), or
graphene and the second material may comprise platinum, titanium,
iridium, brass, gold, nickel alloy, silver, steel (for example

for example, the plurality of electrolysis plates may be fully
immersed in the aqueous electrolyte solution. In certain
embodiments, for example, the positive terminal and the negative
terminal may be in electrical and or electrochemical communication
only or at least substantially through the plurality of plates and
electrolyte solution present in the regions between adjacent
plates. In certain embodiments, for example, electrical and/or
electrochemical communication through the plurality of plates and
electrolyte solution present in the regions between adjacent plates
may be increased (for example maximized) by insulating a portion of
the plurality of plates, for example by seating the stack of plates
in a slot of the pressurized container and/or at least partially
isolating the fluid situated between adjacent plates in a plate
stack with spacers, gaskets, and or sealants between the adjacent
plates.
[0382] In certain embodiments, for example, the electrolysis cell

least partially reacted or quenched) by exposure to air. In certain
embodiments, for example, the HHO may be stored air-free (or at
least substantially air-free) for at least 2 weeks (for example at
least 1 month) without any noticeable change in performance when
used as a second fuel in the internal combustion engine. In certain
embodiments,

liters, in the range of 2-4 liters, or the required amount of HHO
gas may be in the range of 2-3 liters per hour or per 120,000
crankshaft rotations, based on a gas temperature of within
20.degree. C. of the temperature of engine coolant and a pressure

the foregoing ranges of the required amount of HHO gas may
correspond to an average hourly requirement over typical driving
conditions, for example an average hourly requirement over 10,000
miles or over 20,000,000 crankshaft rotations under typical driving

revolutions of the crankshaft of the engine, for example in the
range of 1-8 liters of HHO gas, in the range of 2-7 liters of HHO
gas, or the electrolysis cell may be capable of delivering in the
range of 2-5 liters of HHO gas for every 120,000 revolutions of the
crankshaft of the engine. In certain embodiments, for example, any
of the above values and/or ranges of the required amount may be
based on the volume of HHO gas delivered from an electrolysis cell
at the outlet pressure of the electrolysis cell (for example 45-50
psia). In certain embodiments, for example, any of the above values
and/or ranges of the required amount may be based on a volume of
HHO gas as calculated at a standard temperature and pressure (for
example, a standard temperature of 25.degree. C. and a standard
pressure of 1 atmosphere). In certain embodiments, for example, any
of the above values and/or ranges of the required amount may be
based on the volume of the HHO gas at the outlet temperature and
pressure of an engine coolant-cooled flow regulator in
communication with at least one HHO gas injector (for example an
outlet temperature within 20.degree. C. of the temperature of
engine coolant entering the flow regulator and a pressure of 45 psi
above an inlet air pressure of the internal combustion engine.
[0394] In certain embodiments, for example, the electrolysis cell
may store a volume of HHO gas sufficient to deliver the required

internal combustion engine, for example at least 10,000 crankshaft
revolutions, 15,000 crankshaft revolutions, 20,000 crankshaft
revolutions, or the electrolysis cell may store a volume of HHO gas
sufficient to deliver the required amount of HHO gas for at least
50,000 crankshaft revolutions of the internal combustion engine. In
certain further embodiments, for example, the temperature of the
electrolysis cell may not exceed 80.degree. C. during operation,
for example the temperature of the electrolysis cell may not exceed
may not exceed 65.degree. C. during operation. In certain
embodiments, for example, the temperature of the electrolysis cell

VDC. In certain embodiments, for example, the electrolysis cell may
be powered by a DC power source having a voltage of 24 VDC, or the
electrolysis cell may be powered by a DC power source having a
voltage of 28 VDC.
[0396] In certain further embodiments, for example, the

solution may be selected, maintained, and/or adjusted to provide an
average (or maximum) current draw of less than 20 amps, 15 amps, or
less than 10 amps at the operating temperature of the electrolysis
cell. In certain embodiments, for example, the electrolysis cell
may be configured to operate on less than 250 watts of DC power,
for example the electrolysis cell may be configured to operate on
less than 150 watts of DC power. In certain embodiments, for
example, the electrolysis cell may be configured to have less than
20 ohm of resistance, for example less than 10 ohm, less than 5
ohm, or the electrolysis cell may be configured to have less than 3

of the HHO gas per liter of cylinder displacement may be delivered
to each of the one or more cylinders at a pressure of less than 300
kPa (for example less than 200 kPa, less than 150 kPa, or less than
110 kPa).
[0398] Certain embodiments may provide, for example, method for
reducing one or more emissions of an internal combustion engine,
comprising: controlling a temperature of an HHO gas by exchanging
heat with an engine coolant; and delivering an HHO gas at the
controlled temperature to at least one intake port of the internal

[0402] In certain embodiments, for example, the methods, systems,
and/or apparatus of the present disclosure may comprise a heat
exchanger configured to receive an HHO gas stream. In certain
embodiments, for example, the heat exchanger may be configured to
heat the HHO gas stream. In certain embodiments, for example, the
heat exchanger may be configured to cool the HHO gas stream. In
certain embodiments, for example, the heat exchanger may be
configured to receive a heat transfer medium to heat or cool the
HHO gas stream. In certain embodiments, for example, the rate of
heat transfer medium passed through the heat exchanger may be
controlled to maintain the HHO gas stream at a temperature within a
predetermined range or proximate a temperature set point (for
example within .+-.2.degree. F., within .+-.5.degree. F., within
.+-.10.degree. F., within .+-.15.degree. F., or within
.+-.20.degree. F. of the a temperature set point). In certain
embodiments, for example, the heat transfer medium may be an engine
coolant stream. In certain embodiments, for example, the heat
transfer medium may be an engine exhaust stream. In certain
embodiments, for example, the heat transfer medium may be a diesel
particulate filter (DPF) burner exhaust stream. In certain
embodiments, for example, the heat exchanger may be integral with
an HHO gas generation system. In certain embodiments, for example,
the heat exchanger may be part of an HHO gas distribution
system.
[0403] The heat exchanger may be any suitable heat exchanger. In
certain embodiments, for example, the heat exchanger may be a shell
and tube heat exchanger wherein the HHO gas stream enters a first
end of a tube portion of the heat exchanger through an inlet,
passes thorough an inner channel defined by the tube portion, and
exits the heat exchanger through a second end of the tube. In this
embodiment, for example, the heat transfer medium (for example
engine exhaust gas and/or engine coolant) may flow through an outer
channel defined by a shell portion of the heat exchanger. In
certain other embodiments, for example, the heat transfer medium
may flow through the inner channel and the HHO gas may flow through
the outer channel. In certain embodiments, for example, the shell
and tube heat exchanger may be operated in a parallel flow
configuration. In certain embodiments, for example, the shell and
tube heat exchanger may be operated in a countercurrent flow
configuration. In certain embodiments, for example, the tube
portion may be a straight tube (for example a 1/8 inch thick copper
or steel tube having a working length in the range of 3-8 inches).
Other types of heat exchangers are contemplated. In certain
embodiments, for example, the heat exchanger may be in a spiral
configuration. In certain embodiments, for example, the heat
exchanger may a plate-and-frame heat exchanger. In certain
embodiments, for example, the heat exchanger may be a rotating bed
heat exchanger.
[0404] Certain embodiments may provide, for example, a method of
delivering HHO gas to a combustion chamber of an internal
combustion engine. In certain embodiments, for example, the HHO gas
may be delivered at a controlled temperature. In certain further
embodiments, for example, the controlled temperature may be within
20.degree. C. of an engine coolant temperature (for example the
temperature of an inlet coolant supplied to an inlet side of a heat
exchanger positioned upstream of the combustion chamber, such as
positioned proximate a regulator for HHO gas flow into the
combustion chamber), for example the temperature may be within
15.degree. C., within 10.degree. C., or the controlled temperature
may be within 5.degree. C. of an engine coolant temperature. In
certain further embodiments, for example, the controlled
temperature may be no more than 20.degree. C. above an engine
coolant temperature (for example the temperature of an inlet
coolant supplied to an inlet side of a heat exchanger), for example
the temperature may be no more than 15.degree. C., no more than
10.degree. C., or the controlled temperature may be no more than
5.degree. C. above an engine coolant temperature. In certain
further embodiments, for example, the controlled temperature may be
no more than 20.degree. C. below an engine coolant temperature (for
example the temperature of an inlet coolant supplied to an inlet
side of a heat exchanger), for example the temperature may be no
more than 15.degree. C., no more than 10.degree. C., or the
controlled temperature may be no more than 5.degree. C. below an
engine coolant temperature.
[0405] In certain embodiments, for example, the HHO gas may be
under pressure when introduced to an internal combustion engine. In
certain embodiments, for example, the HHO gas may be introduced at
a pressure in the range of 50-500 kPa above the pressure of an
intake port of the combustion chamber of the internal combustion
engine, for example in the range of 50-300 kPa above the pressure
of an intake port, in the range of 100-200 kPa, in the range of
45-50 psi, or the HHO gas may be introduced at a pressure in the
range of 100-150 kPa above the pressure of an intake port of the
combustion chamber.
[0406] In certain embodiments, for example, the HHO gas may be
introduced at a pressure in the range of 45-50 psi above the
pressure of an intake port combustion chamber and at a temperature
within 30.degree. C. of an inlet coolant supplied to an inlet side
of a heat exchanger. In certain embodiments, for example, use of
the engine coolant to control the temperature of the HHO gas and/or
controlling the introduction pressure of the HHO gas (for example
by using a pressure regulator) may allow pre-determined amounts of
the HHO gas to be introduced to the internal combustion engine. In
certain embodiments, for example, the aforesaid temperature and/or
pressure controls may provide more precise control over the amount
of HHO gas introduced into the internal combustion engine in
comparison to a system lacking said controls (for example a
traditional system for introducing electrolysis gases into an
internal combustion engine).
[0407] Certain embodiments may provide, for example, apparatus,
methods, or systems to improve the performance of an internal
combustion engine. In certain embodiments, for example, the
internal combustion engine may include gasoline engines, diesel

in the range of between 1-50%, for example between 1-5%, between
5-10%, between 5-25%, between 7-12%, between 10-20%, between
15-25%, between 20-25%, between 20-30%, between 20-50%, between
30-35%, between 30-38%, between 40-50%, between 40-45%, or between
44-50%.

20%, more than 30%, more than 40%, more than 50%, more than 60%,
more than 70%, more than 80%, more than 90%, or more than 99%
combustion of the hydrocarbon fuel provided to the internal
combustion engine. In certain embodiments, for example,
substantially complete combustion may be more than 80%, for example
more than 85%, more than 90%, more than 95%, more than 96%, more
than 97%, more than 98%, or more than 99% combustion of the
hydrocarbon fuel provided to the internal combustion engine.
[0410] Certain embodiments may provide, for example, apparatus,
methods, or systems to improve the operation of the internal
combustion engine. In certain embodiments, one or more than one
(including for instance all) of the following embodiments may
comprise each of the other embodiments or parts thereof. In certain
embodiments, for example, the internal combustion engine may
operate at a cooler temperature and/or may run cleaner. In certain
embodiments, for example, the internal combustion engine may
generate more power for the same or lower amount of fuel. In
certain embodiments, for example, the internal combustion engine
may generate exhaust temperatures more suitable for efficient
operation of exhaust aftertreatment systems. In certain
embodiments, for example, the internal combustion engine may
generate exhaust temperatures more suitable for efficient operation
of diesel particulate filter (DPF). In certain embodiments, for
example, the internal combustion engine may generate exhaust
temperatures more suitable for efficient operation of selective
catalytic reactor (SCR). In certain embodiments, for example, the
internal combustion engine may generate exhaust temperatures more
suitable for efficient operation of diesel oxidation catalyst
(DOC). In certain embodiments, for example, the internal combustion
engine may generate exhaust temperatures more suitable for
efficient operation of NOx trap.
[0411] Certain embodiments may provide, for example, apparatus,
methods, or systems to introduce a second fuel (for example a
second fuel exclusive of a petroleum-derived fuel) into an internal
combustion engine. In certain embodiments, for example, the second
fuel (or booster gas or enhancement gas) comprises hydrogen, oxygen
and/or mixtures thereof. In certain embodiments, for example, the
second fuel may substantially comprise hydrogen, oxygen and/or
mixtures thereof. In certain embodiments, for example, the second
fuel may predominantly comprise hydrogen, oxygen and/or mixtures
thereof. In certain embodiments, for example, the second fuel may
be a product of electrolysis.
[0412] Certain embodiments may provide, for example, apparatus,
methods, or systems to produce an oxygen-hydrogen gas mixture (for
example an oxygen-hydrogen gas mixture for use as a second fuel in
an internal combustion engine). In certain embodiments, for
example, the gas mixture may be an oxygen-rich or hydrogen-rich a
gas mixture. In certain embodiments, for example, the gas mixture
may comprise at least one or more of the following aqueous

ions, oxygen ions, mononuclear oxygen, mononuclear ozone, singlet
oxygen, hydroxide ions, hydronium ions, superoxide, hydrogen
superoxide, hydroxide radical, peroxide radical, ionic peroxide,

In certain embodiments, for example, in exemplary embodiments, the
gas mixture may be a gas mixture comprising at least hydrogen ions
and oxygen ions, or diatomic oxygen and diatomic hydrogen, or

[0413] Certain embodiments may provide, for example, apparatus,

produced may be modified before being delivered to the internal
combustion engine. In certain embodiments, for example, the gas
mixture may be combined with an additive and/or the composition of
the gas mixture may be modified by adding, recycling or removing
portions of the gas mixture. In certain embodiments, for example,
the electrolysis process may generate a hydrogen to oxygen ratio of
between 1.8:1 to 2.3:1, for example a hydrogen to oxygen ratio of
2:1 and the system may be configured to deliver a gas mixture
having a hydrogen to oxygen ratio of less than 2:1, for example a

1.5:1 or less, 1.3:1 or less, by removing, or recycling, a portion
of the hydrogen from the gas mixture prior to delivery.
Alternatively, in certain embodiments, for example, an apparatus,
method, or system may generate hydrogen and oxygen at a hydrogen to
oxygen ratio of 2:1, but some of the hydrogen or oxygen, for
example oxygen, may be trapped in bubbles, and the apparatus,
method, or system may be configured to release the trapped oxygen
to effectively deliver more oxygen to the internal combustion
engine.
[0414] Certain embodiments may provide, for example, apparatus,
methods, or systems to produce a gas mixture that is approximately
two parts oxygen to one part hydrogen (for example 2:1) or less
than 2:1 (for example 1.75:1, 1.5:1, 1.25:1, 1:1, etc.). In certain

in real time (or substantially real time), so as to provide
predetermined or controlled quantity of gas, for example, in
relation to the engine speed and/or demand.
[0416] Certain embodiments may provide, for example, apparatus,
methods, or systems to utilize a substantially closed-loop system
that recycles a water-reagent (or water-electrolyte or aqueous
electrolyte solution electrolysis component) mixture in an effort
to reduce its consumption.

[0420] Certain embodiments may provide, for example, apparatus,
methods, or systems to generate a gas mixture that is an accelerant
to speed combustion, enhance combustion, and/or increase the extent
of combustion.
[0421] Certain embodiments may provide, for example, apparatus,
methods, or systems to displace air with oxygen and/or hydrogen
within the engine's intake system. In certain embodiments, one or
more than one (including for instance all) of the following
embodiments may comprise each of the other embodiments or parts
thereof. In certain embodiments, for example, an apparatus, method,
or system may displace air within the engine's intake system with
the gas mixture, resulting from the gas mixture generator system.
In certain embodiments, for example, an apparatus, method, or
system may be used to create a shorter combustion process that
lowers the engine temperature thereby reducing the formation of
nitrogen oxides. In certain embodiments, for example, an apparatus,
method, or system may generate a gas mixture resulting from
electrolysis of an aqueous electrolyte solution and introducing at
least a portion of the gas mixture into the engine's intake for
improved combustion. In certain embodiments, for example, an
apparatus, method, or system may generate a gas mixture resulting
from electrolysis of an aqueous electrolyte solution and
introducing a substantial portion (for example greater than 95 wt.
%), of the gas mixture into the engine's intake for improved
combustion. In certain embodiments, for example, an apparatus,
method, or system may generate a gas mixture resulting from
electrolysis of an aqueous electrolyte solution and storing the gas
mixture in a storage tank instead of introducing the gas mixture
into the engine's intake. In certain embodiments, for example, an
apparatus, method, or system may generate an optimized or partially
optimized quantity of a gas mixture, such as a gas mixture having
one or more aqueous electrolyte solution electrolysis components,
into the engine's intake for improved combustion. In certain
embodiments, for example, an apparatus, method, or system may be
configured to produce in the range of between 1-7.5 liters of gas
per minute, such as 1.2, 1.7, 2.0, 2.9, 3.5, 5.0, or 7.0 liters of

0.50, 0.6, or 0.70 liters of gas per minute per liter of engine
displacement. In certain embodiments, for example, an apparatus,
method, or system may be configured to produce in the range of
between 0.25-3 liters of gas per minute, such as between 0.25-2.5,
between 0.25-2, between 0.25-1.5, between 0.25-1, between
0.25-0.50, between 0.50-0.75, between 0.5-2.5, between 0.5-1.5,
between 0.75-1, between 1-2, between 1-3, between 1-1.5, between
1.25-1.75, between 1.5-2, between 2-2.5, between 2.5-3 liters of
gas per minute.
[0422] Certain embodiments may provide, for example, a system or
apparatus to generate a gas mixture for use with an internal
combustion engine, the system or apparatus comprising a tank
configured to store an aqueous electrolyte solution consisting
essentially of water and a predetermined quantity of electrolyte
(reagent). In certain embodiments, one or more than one (including
for instance all) of the following embodiments of the system or
apparatus may comprise each of the other embodiments or parts
thereof. In certain embodiments, for example, the system or
apparatus may further comprise a cell (i.e., an electrolytic cell)
configured for aiding in the electrolysis of the aqueous
electrolyte solution. In certain further embodiments, for example,
the cell may comprise a plurality of plates arranged substantially
parallel to one another and be spaced substantially equidistant
from an adjacent one of the plurality of plates, and at least one
seal located between the plurality of plates. In certain
embodiments, for example, the at least one seal may comprise a
relatively hard plastic portion with a first thickness for
maintaining the predetermined distance between adjacent plates, and
a relatively soft sealing portion, typically, a soft, often rubber
or rubber-like portion, with a second thickness for maintaining the
substantially airtight and substantially watertight seal between
adjacent ones of the plurality of plates.
[0423] In certain embodiments, for example, the system or apparatus
may further comprise a controller configured to apply a pulse width
modulated voltage to the cell to generate the gas mixture within
the cell. In certain further embodiments, for example, the
controller may be configured to regulate the current provided to
the cell by controlling the duty cycle of the pulse width modulated
voltage. In certain embodiments, for example, the duty cycle may be
controlled in real time and/or substantially real time.
[0424] In certain embodiments, for example, the system or apparatus
may further comprise an output for outputting the gas mixture to
the internal combustion engine.
[0425] In certain embodiments, for example, the gas mixture may be
input into the tank prior to being output to the internal
combustion engine. In certain embodiments, for example, the gas
mixture may be output to the internal combustion engine without
being input into the tank. In certain embodiments, for example, the
gas mixture may be stored in the tank without being output to the
internal combustion engine under certain operating conditions. In
certain embodiments, for example, the gas generation system or
apparatus may be integral with the gas storage tank.
[0426] In certain embodiments, for example, the tank may be
manufactured of a material that is non-conductive.
[0427] In certain embodiments, for example, the electrolyte may be
a metal salt, such as a metal salt at least partially soluble in
water. In certain embodiments, for example, the electrolyte
solution (for example an aqueous electrolyte solution) may comprise
a salt selected from the group consisting of: KOH, NaOH,
Na.sub.2CO.sub.3, NaHCO.sub.3, NaCl, K.sub.2CO.sub.3, KHCO.sub.3,
H.sub.2SO.sub.4, CH.sub.3COOH, and a combination of two or more
thereof.
[0428] In certain embodiments, for example, the size of the tank
may be selected such that the aqueous electrolyte solution occupies
less than 1/4, 1/3, 1/2, 2/3, or 3/4, the volume of the tank during
operation. In certain embodiments, for example, the tank may have a
capacity of 2, 3, 4, 5, 6, 7, 8, 9, or 10 liters. In certain
embodiments (for example for larger applications), for example, the
tank may be even larger. In certain embodiments, for example, the
system or apparatus may comprise multiple tanks.
[0429] In certain embodiments, for example, the cell may comprise
at least two plates, a first plate configured to be coupled to a
positive terminal of a voltage source and a second plate configured
to be coupled to a negative terminal of the voltage source. In
certain embodiments, for example, the cell may further comprise at
least one neutral plate configured in a series relationship to the
first plate and the second plate. In certain embodiments, for
example, the cell may comprise at least 2, at least 3, at least 4,
at least 5, at least 6, at least 7, at least 8, at least 9, at
least 10, at least 11, at least 12, at least 13, at least 14, or at
least 15 neutral plates. In certain embodiments, for example, the
number of neutral plates may be selected to obtain a desired
voltage drop between the plates.
[0430] In certain embodiments, for example, the soft rubber portion
of the at least one seal may be positioned on an inner edge of the
hard plastic portion of the seal.
[0431] In certain embodiments, for example, the soft rubber portion
may be located on the outer edge of hard plastic portion. In
certain embodiments, for example, the seal may comprise at least
two soft plastic portions--a first soft plastic portion may be
located between the interface of the hard plastic portion and a
first one of the adjacent plates and a second soft plastic portion
may be located between the interface of the hard plastic portion
and a second one of the adjacent plates. In certain embodiments,
for example, the soft plastic portion may surround the hard plastic
portion of the seal. In certain embodiments, for example, the
thickness of the soft rubber portion may be larger than the
thickness of the hard plastic portion of the seal. In certain
embodiments, for example, the hard plastic portion may be 0.002'',
0.003'', 0.004'', 0.005'', 0.006'''', 0.007'', 0.008'', 0.009'',
0.010'', 0.0125'', 0.025'', 0.0375'', 0.050'', 0.0625'', or 0.075''
thick. In certain embodiments, for example, the soft rubber portion
may be 0.002'', 0.003'', 0.004'', 0.005'', 0.006'', 0.007'',
0.008'', 0.009'', 0.010'', 0.011'', 0.012'', 0.13'', 0.014'',
0.030'', 0.038'', 0.055'', 0.0675'', or 0.080'' thick. In certain
embodiments, for example, the hard plastic portion may be
manufactured from a material selected such that the hard plastic
portion does not significantly react with the aqueous electrolyte
solution. In certain embodiments, for example, the hard plastic
portion may be manufactured from high density polyethylene (HDPE),
polyphthalamide (PPA), styrene, nylon, or combinations thereof. In
certain embodiments, for example, the soft rubber portion may be
manufactured from a material selected such that the soft rubber
portion does not significantly react with the aqueous electrolyte
solution. In certain embodiments, for example, the soft rubber
portion may be manufactured from ethylene propylene diene monomer
(EPDM).
[0432] In certain embodiments, for example, the internal combustion
engine may be a turbocharged diesel engine and the gas mixture may
be input into the turbocharged diesel engine up stream of an intake
valve or valves. In certain embodiments, for example, the internal
combustion engine may comprise a nonroad engine, a stationary
engine, a locomotive engine, a marine engine, an aircraft engine,
or a generator set engine. In certain embodiments, for example, the
internal combustion engine may comprise a spark-ignition engine, a
compression-ignition engine, a naturally aspirated engine, a
turbocharged engine, a turbocompound engine, a supercharged engine,
a direct injection engine, an indirect injection engine, or a port
injection engine. In certain embodiments, for example, the internal
combustion engine may comprise a gasoline engine, a diesel engine,
an ethanol engine, a methanol engine, a biofuel engine, a natural
gas engine, a propane engine, or an alternative fuel engine.
[0433] In certain embodiments, for example, apparatus, methods, or
systems may comprise a scrubber. In certain embodiments, for
example, the scrubber may comprise a switch configured to sense
excess liquid and/or moisture in the form of foam in the gas stream
and shut-off the electrolysis process to prevent the excess
moisture from entering the internal combustion engine, and/or the
accumulation of the gas mixture. In certain embodiments, for
example, the apparatus, methods, or systems may be exclusive of a
scrubber. For example, HHO gas may be generated and/or stored at a
temperature (for example a temperature in the range of
100-110.degree. F.) that avoids excess and/or moisture and
therefore makes a scrubber unnecessary.
[0434] Certain embodiments may provide, for example, HHO gas that
is generated and distributed moisture-free. Moisture-free HHO gas
includes HHO gas free of entrained water droplets wherein the HHO
gas is saturated with water at a sufficiently low temperature
(and/or high pressure) such that no water condenses from the HHO
gas during distribution from an electrolysis unit to an internal
combustion engine. In certain embodiments, for example, the
moisture-free HHO gas may have no more than 0.062 g/cm.sup.3 (for
example no more than 0.06 g/cm.sup.3, no more than 0.05 g/cm.sup.3,
or no more than 0.04 g/cm.sup.3) water. In certain embodiments, for
example, the moisture-free HHO gas may be saturated with water at a
temperature of no more than 120.degree. F. (for example no more
than 110.degree. F. or no more than 100.degree. F.) at a pressure
in the range of 40-60 psig (for example a pressure in the range of
45-50 psig).
[0435] Certain embodiments may provide, for example, apparatus,
methods, or systems to realize a fuel economy increase of at least
1%, for example at least 2%, at least 5%, at least 10%, at least
15%, at least 20%, at least 25%, at least 30%, at least 35%, at
least 40%, at least 45%, at least 50%, or more. In certain
embodiments, for example, the fuel economy increase may be in the
range of between 1-50%, for example between 1-5%, between 5-10%,
between 5-25%, between 7-12%, between 10-20%, between 15-25%,
between 20-25%, between 20-30%, between 20-50%, between 30-35%,
between 30-38%, between 40-50%, between 40-45%, or between
44-50%.
[0436] Certain embodiments may provide, for example, apparatus,
methods, or systems to improve the operation of an internal
combustion engine. In certain embodiments, for example, the
internal combustion engine may operate at a cooler temperature
and/or may run cleaner.
[0437] Certain embodiments may provide, for example, apparatus,
methods, or systems to produce an oxygen-hydrogen gas mixture, such
as an oxygen-rich, oxygen-hydrogen gas mixture, or a hydrogen-rich
oxygen-hydrogen gas mixture. In certain embodiments, one or more
than one (including for instance all) of the following embodiments
of the system or apparatus may comprise each of the other
embodiments or parts thereof. In certain embodiments, for example,
the gas mixture may be a low temperature plasma. In certain
embodiments, for example, the plasma may be a cleaner plasma than
that produced by other systems and/or methods. In certain
embodiments, for example, the plasma may be an oxygen rich plasma.
In certain embodiments, for example, the gas mixture may be an
oxygen-rich or a hydrogen-rich gas mixture. In certain embodiments,
for example, the gas mixture may comprise at least one or more of
the following: aqueous electrolyte solution electrolysis
components: monatomic oxygen, diatomic oxygen, monatomic hydrogen,
diatomic hydrogen, hydrogen ions, oxygen ions, mononuclear oxygen,
mononuclear, ozone, singlet oxygen, hydroxide ions, hydronium ions,
superoxide, hydrogen superoxide, hydroxide radical, peroxide
radical, ionic peroxide, combinations of one or more of these
and/or mixtures of the same. In certain embodiments, for example,
the gas mixture may be a gas mixture comprising at least hydrogen
ions and oxygen ions, or diatomic oxygen and diatomic hydrogen, or
oxygen ion and diatomic oxygen, etc. In certain embodiments, for
example, the oxygen-hydrogen gas mixture may be an oxygen-rich gas
mixture, an oxygen-hydrogen gas mixture, or a hydrogen-rich
oxygen-hydrogen gas mixture. In certain embodiments, for example,
the gas mixture may comprise approximately two parts hydrogen to
one part oxygen (for example a ratio of hydrogen to oxygen of 2:1)
or less than 2:1 (for example a ratio of hydrogen to oxygen of less
than 1.75:1, less than 1.5:1, less than 1.25:1, less than 1:1, less
than 0.75:1, or a ratio of hydrogen to oxygen of less than 0.5:1,
etc.). In certain embodiments, for example, the gas mixture
produced may be modified before being delivered to the internal
combustion engine. In certain embodiments, for example, the gas
mixture may be combined with an additive and/or the composition of
the gas mixture may be modified by adding or removing portions of
the gas mixture. In certain embodiments, for example, an
electrolysis process may generate a gas mixture having a hydrogen
to oxygen ratio in the range of between 1.8:1 to 2.3:1, for example
a hydrogen to oxygen ratio of 2:1, and an apparatus, system, or
method may be capable of delivering a gas mixture having a hydrogen
to oxygen ratio of less than 2:1, for example a ratio of 1.8:1 or
less, 1.7:1 or less, 1.5:1 or less, 1.3:1 or less, by removing, or
recycling, a portion of the hydrogen from the gas mixture prior to
delivery. Alternatively, in certain embodiments, for example, the
apparatus, system, or method may be capable of generating a 2:1
ratio of hydrogen to oxygen but some of the hydrogen or oxygen, for
example oxygen, may be trapped in bubbles, and the apparatus,
system, or method may be configured to enable the release of the
trapped oxygen to effectively deliver more oxygen to the internal
combustion engine. Certain embodiments, for example, may comprise
methods capable of producing a gas mixture that is approximately
two parts oxygen to one part hydrogen (for example 2:1) or less
than 2:1 (for example 1.75:1, 1.5:1, 1.25:1, 1:1, etc.). In certain
embodiments, for example, an electrolysis process may generate
between an oxygen to hydrogen ratio in the range of between 1.8:1
to 2.3:1, for example a 2:1 ratio of oxygen to hydrogen and the
apparatus, system, or method may be capable of delivering a gas
mixture having an oxygen to hydrogen ratio of less than 2:1, for
example an oxygen to hydrogen ratio of 1.8:1 or less, 1.7:1 or
less, 1.5:1 or less, 1.3:1 or less. In certain embodiments, for
example, the apparatus, system, or method may be capable of
delivering a gas mixture having an oxygen to hydrogen ratio of less
than 3.5:1, less than 3:1, less than 2.75:1, less than 2.5:1 oxygen
to hydrogen.
[0438] Certain embodiments may provide, for example, apparatus,
methods, or systems to more reliably controlled gas mixture
generation process. In certain embodiments, for example, the
current provided for gas generation may be continually or
continuously regulated or controlled, for example, in real time (or
substantially real time), so a predetermined quantity of gas is
consistently produced.
[0439] Certain embodiments may provide, for example, apparatus,
methods, or systems to utilize a substantially closed-loop method
of electrolysis that recycles a water-reagent (or water-electrolyte
or aqueous electrolyte solution electrolysis component) mixture in
an effort to reduce its consumption.
[0440] Certain embodiments may provide, for example, apparatus,
methods, or systems capable of altering combustion (for example
diesel combustion) chemistry to reduce particulate formation. In
certain embodiments, for example, the methods may be capable of
achieving a reduction in particulate formation from an internal
combustion engine of greater than 5%, for example greater than 10%,
greater than 15%, greater than 20%, greater than 25%, greater than
30%, greater than 35%, greater than 40%, greater than 50%, greater
than 60%, greater than 75%, greater than 80%, greater than 90%,
greater than 95% or close to 100%. In certain embodiments, for
example, the concentration of an oxidizer in an internal combustion
engine may be increased. In certain embodiments, for example, the
increase in the amount of oxidizers may be at least 5%, for example
at least 10%, at least 15%, at least 20%, at least 25%, at least
30%, at least 35%, at least 40%, at least 45%, or at least 50%. In
certain embodiments, for example, the increase in the amount of
oxidizers may be in the range of between 5-50%, such as between
5-25%, between 10-20%, between 10-40%, between 15-25%, between
20-30%, between 25-35%, between 25-50%, between 30-40%, between
40-50%, between 35-45%, or between 40-50%.
[0441] Certain embodiments may provide, for example, apparatus,
methods, or systems to distribute the oxidizer for more even
air/fuel mixture.
[0442] Certain embodiments may provide, for example, apparatus,
methods, or systems to generate a gas mixture that is an accelerant
to speed combustion and/or increase combustion completion.
[0443] Certain embodiments may provide, for example, apparatus,
methods, or systems to displace air with oxygen and/or hydrogen
within the engine's intake system.
[0444] Certain embodiments may provide, for example, apparatus,
methods, or systems to create a shorter combustion process that
lowers the engine temperature thereby reducing the formation of
nitrogen oxides.
[0445] Certain embodiments may provide, for example, apparatus,
methods, or systems to generate an optimized or partially optimized
quantity of a gas mixture, such as a gas mixture having one or more
aqueous electrolyte solution electrolysis components, into the
engine's intake for improved combustion. In certain embodiments,
for example, the apparatus, methods, or systems may be capable of
producing in the range of between 1-7.5 liters of gas per minute,
such as 1.2, 1.7, 2.0, 2.9, 3.5, 5.0, or 7.0 liters of gas per
minute, and/or produce in the range of between 0.08-0.75 liters of
gas per minute per liter of engine displacement, such as 0.1, 0.12,
0.17, 0.20, 0.25, 0.29, 0.3, 0.32, 0.35, 0.4, 0.45, 0.50, 0.6, or
0.70 liters of gas per minute per liter of engine displacement. In
certain embodiments, for example, the apparatus, methods, or
systems may be capable of producing in the range of between 0.25-3
liters of gas per minute, such as between 0.25-2.5, between 0.25-2,
between 0.25-1.5, between 0.25-1, between 0.25-0.50, between
0.50-0.75, between 0.5-2.5, between 0.5-1.5, between 0.75-1,
between 1-2, between 1-3, between 1-1.5, between 1.25-1.75, between
1.5-2, between 2-2.5, between 2.5-3 liters of gas per minute.
[0446] Certain embodiments may provide, for example, apparatus,
methods, or systems to reduce the particulate emissions of an
internal combustion engine. In certain embodiments, for example, a
method may comprise the steps of generating a gas mixture for use
within the internal combustion engine and providing the gas mixture
to the internal combustion engine during operation of the internal
combustion engine. In certain embodiments, for example, a method
may comprise: generating a gas mixture for use within the internal
combustion engine, and providing the gas mixture to the internal
combustion engine during operation of the internal combustion
engine. In certain embodiments, for example, the gas mixture may be
generated in substantially real time relative to the consumption of
the gas mixture. In certain embodiments, for example, the gas
mixture may be generated onboard the vehicle during operation of
the internal combustion engine.
[0447] Certain embodiments may provide, for example, apparatus,
methods, or systems wherein a tank may be at least partially filled
with an aqueous electrolyte solution consisting essentially of
water and a predetermined quantity of electrolyte (reagent). In
certain embodiments, for example, the apparatus, methods, or
systems may perform electrolysis of the aqueous electrolyte
solution within a cell (i.e., an electrolytic cell) configured for
aiding in the electrolysis of the aqueous electrolyte solution.
EXAMPLES
Example 1
[0448] A series of electrolysis cells were studied with different
plates. In one cell, uncoated stainless steel plates were used and
in a second cell platinum-coated stainless steel plates were used.
The electrolyte concentration, of potassium carbonate in water, was
adjusted in the cell with uncoated plates such that the current
draw was essentially identical. All other conditions were
essentially identical. The following table reports the results.
TABLE-US-00001 TABLE 1 Performance Feature Uncoated versus Coated
Plates Electrolyte Uncoated plates required approximately 3 times
Concentration greater concentration. HHO Gas Uncoated plates
produced approximately 50% less Production HHO gas. Current Draw
After 4 hours of testing, the cells with uncoated plates had a
noticeably lower electrolyte level resulting in lower current draw.
Experimental Note: Iridium-coated plates performed similar to
platinum coated plates
Example 2
[0449] A series of electrolysis cells were studied with different
plates. In a first cell, 7 platinum coated stainless steel plates
were used and in a second cell 5 platinum coated stainless steel
plates were used. The current draw was kept essentially the same
for both cells during the test procedure, by adjusting the
concentration of the electrolyte in the 7-plate cell to almost
twice the concentration of the 5-plate cell. All other conditions
were essentially identical. The following table reports the
results.

[0452] All publications and patent applications mentioned in this
specification are herein incorporated by reference to the same
extent as if each individual publication or patent application was
specifically and individually indicated to be incorporated by
reference.
[0453] While several embodiments of the present invention have been
described and illustrated herein, those of ordinary skill in the
art will readily envision a variety of other means and/or
structures for performing the functions and/or obtaining the
results and/or one or more of the advantages described herein, and
each of such variations and/or modifications is deemed to be within
the scope of the present invention. More generally, those skilled
in the art will readily appreciate that all parameters, dimensions,
materials, and configurations described herein are meant to be
exemplary and that the actual parameters, dimensions, materials,
and/or configurations will depend upon the specific application or
applications for which the teachings of the present invention
is/are used. Those skilled in the art will recognize, or be able to
ascertain using no more than routine experimentation, many
equivalents to the specific embodiments the invention described
herein. It is, therefore, to be understood that the foregoing
embodiments are presented by way of example only and that, within
the scope of the appended claims and equivalents thereto, the
invention may be practiced otherwise than as specifically described
and claimed. The present invention is directed to each individual
feature, system, article, material, and/or method described herein.
In addition, any combination of two or more such features, systems,
articles, materials, and/or methods, if such features, systems,
articles, materials, and/or methods are not mutually inconsistent,
is included within the scope of the present invention.
[0454] The indefinite articles "a" and "an," as used herein in the
specification and in the claims, unless clearly indicated to the
contrary, should be understood to mean "at least one."
[0455] The phrase "and/or," as used herein in the specification and
in the claims, should be understood to mean "both or either or in a
series having more than two elements all or a subset of all
elements or just one of the elements" Thus, as a non-limiting
example, a reference to "A, B and/or C," is understood to include
A, B and C, A and B, A and C, B and C, and A or B or C. As used
herein in the specification and in the claims, the phrase "at least
one," in reference to a list of one or more elements, should be
understood to mean at least one element selected from any one or
more of the elements in the list of elements, but not necessarily
including at least one of each and every element specifically
listed within the list of elements and not excluding any
combinations of elements in the list of elements. This definition
also allows that elements may optionally be present other than the
elements specifically identified within the list of elements to
which the phrase "at least one" refers, whether related or
unrelated to those elements specifically identified. Thus, as a
non-limiting example, "at least one of A and B" (or, equivalently,
"at least one of A or B," or, equivalently "at least one of A
and/or B") can refer, in one embodiment, to at least one,
optionally including more than one, A, with no B present (and
optionally including elements other than B); in another embodiment,
to at least one, optionally including more than one, B, with no A
present (and optionally including elements other than A); in yet
another embodiment, to at least one, optionally including more than
one, A, and at least one, optionally including more than one, B
(and optionally including other elements); etc.
[0456] In the claims, as well as in the specification above, all
transitional phrases such as "comprising," "including," "carrying,"
"having," "containing," "involving," "holding," and the like are to
be understood to be open-ended, i.e., to mean including but not
limited to. Only the transitional phrases "consisting of" and
"consisting essentially of" shall be closed or semi-closed
transitional phrases, respectively, as set forth in the United
States Patent Office Manual of Patent Examining Procedures, Section
2111.03.

[0458] The subject headings used in the detailed description are
included for the ease of reference of the reader and should not be
used to limit the subject matter found throughout the disclosure or
the claims. The subject headings should not be used in construing

particular embodiments. However, it will be readily apparent to
those skilled in the art that it is possible to embody the
disclosure in specific forms other than those of the embodiments
described above. The embodiments are merely illustrative and should
not be considered restrictive. The scope of the disclosure is given
