Description
PRIORITY
[0001] The present invention claims priority under 35 USC section
119 and based upon a provisional application 60/982,037 filed on
Oct. 23, 2007.
FIELD OF THE INVENTION
[0002] The present invention relates generally to improvements in
hot exhaust gas pipes and mufflers and more particularly relates to
decorative exhaust gas pipes and mufflers including decorative
chrome used on trucks, motorcycles and automobiles and heavy duty
construction equipment such as mining and agriculture equipment.
Furthermore, the present invention relates to cooling the exhaust
gas to eliminate damage due to condensation near the exhaust and to
eliminate damage to the undercarriage.
BACKGROUND OF THE INVENTION
[0003] One of the most critical problems confronting the developers
of vehicle exhaust pipes and mufflers or exhaust pipes and mufflers
which are exposed for appearance purposes has been the prevention
of heat discolorization of the chromed exhaust pipes and muffler
casings from the extreme heat generated by high engine performance.
Another problem is the damage to the undercarriage, components and
anything near the exhaust output due to the extreme heat.
[0004] Although the prior art has been concerned with preventing
heat transfer to the outer housing of a vehicle exhaust system,
none have really accomplished that goal, none have prevented heat
discoloration as the present invention. U.S. Pat. No. 4,356,885 for
a Chambered-Core Motorcycle-Exhaust Apparatus was granted on Nov.
2, 1982 to Christy J. Dello. The exhaust system described in the
Dello patent is concerned with a double wall exhaust system wherein
the inner core is mounted within a tubular housing having a larger
diameter than the inner core so as to establish an annular chamber
between the outer housing and the inner exhaust core. Dello
specifically requires the use of an inner exhaust core system that
has a plurality of interconnected pipe segments.
[0005] U.S. Pat. No. 3,858,678 was granted Jan. 7, 1975 for a
Muffler with Rotary Gas Flow to Ralph Haren. It is directed to a
muffler construction that has an outer shell which is clamped to
the ends of a flow tube which contains flow obstruction devices to
prevent or restrict straight through gas flow.
[0006] U.S. Pat. No. 3,104,733 was granted Sep. 24, 1963 for a
Sound Attenuating Gas Pipe to Edmund Ludlow. It is directed to an
exhaust system which has an outer pipe with a plurality of sections
or inserts mounted within the outer pipe that are coaxially aligned
within the outer pipe to define a main gas flow passage
therethrough. The combination is designed so that each adjacent
pair of inserts act in combination with the adjacent wall of the
outer pipe to define a "resonating chamber of volume".
[0007] U.S. Pat. No. 5,799,395 was granted Sep. 1, 1998 and U.S.
Pat. No. 5,907,134 was granted May 25, 1999 for Air Gap-Insulated
Exhaust Pipe And Process For Manufacturing An Air Gap-Insulated
Exhaust Pipe to Thomas Nording, et al. Both patents are directed to
a double wall exhaust pipe wherein the inner pipe which is
comprised of sections connected by a sliding fit which are
prevented from contacting the walls of the outer pipe as the result
of the thermal expansion of both pipes during operation.
SUMMARY
[0008] An exhaust system to remove exhaust from an engine of a
vehicle may include a first exhaust member to conduct the exhaust
from the engine of the vehicle to the atmosphere and a source of
pressurized fluid to conduct the pressurized fluid to the first
exhaust member to cool the exhaust from the engine of the
vehicle.
[0009] The source of pressurized fluid may be a blower, and the
source of pressurized fluids may be a air dam.
[0010] The blower may be connected to a battery of the vehicle, and
the blower may include a sensor to determine if a predetermined
speed has been reached.
[0011] The sensor may inactivate the blower when the predetermined
speed has been reached.
[0012] The source of pressurized fluid may be compressed air, and
the source of the pressurized fluid may be refrigerated air.
BRIEF DESCRIPTION OF THE DRAWINGS
[0013] The invention may be understood by reference to the
following description taken in conjunction with the accompanying
drawings, in which, like reference numerals identify like elements,
and in which:
[0014] FIG. 1 illustrates a cross-sectional view of the exhaust
system of the present invention;
[0015] FIG. 2 illustrates a portion of the exhaust system of the
present invention;
[0016] FIG. 3 illustrates a alternative of the present
invention.
DETAILED DESCRIPTION
[0017] The present invention achieves lower exhaust temperatures by
mixing the hot engine gases with cooler fluids which may be ambient
air. When the present invention refers to fluid, the fluid may be
air, gas or other types of fluids. A blower which may be an
electric blower mixes the pressurize air with the hot exhaust gases
at the base of the exhaust stack or downstream of the catalytic
converter of the vehicle. Alternatively, the present invention may
employ multiple blowers. The electric blower may operate from the
battery or from the electrical system of the vehicle in order to
power the motor. The blower may be powered by gas, solar or other
forms of energy. The blower may include a sensor to detect back
pressure or a high temperature condition in order to provide safe
operation of electric blower. The sensor may determine the presence
or absence of back pressure and the quantity of back pressure. The
sensor may determine the temperature of the exhaust or the flow
rate of the exhaust. The sensor may provide an indication of the
status of the blower for example whether or not the blower is
operating or not working. The blower may be positioned at an angled
relationship to prevent the air from being forced into the exhaust
such that the air would blow against the exhaust. The tube with the
blower can be inserted into the stream of fluid flow to create a
Venturi effect. Additional air may be directed from the front of
the vehicle and may be received through an input port such as an
air dam. Furthermore, the exhaust system may include a dedicated
blower for each exhaust stack or alternatively, a single blower may
provide the fluid for all of exhaust stacks. As a consequence of
the additional air, the temperature of the exhaust stacks, referred
below as the first and second exhaust members, may be reduced
sufficiently so that the first and second exhaust members may be a
single exhaust tube/stack and that the exhaust stack may be chrome
plated for example with the nickel plating without the fear of
discoloration or damage to the chrome. Additionally, the teachings
of the present invention may eliminate the damage to the
surrounding components including the undercarriage or anything near
the output of the exhaust such as people or dry brush. The
teachings of the present invention may be applied to any vehicles
such as a motorcycle, truck, automobile, airplane, boat, heavy-duty
construction equipment, agricultural equipment, mining equipment or
other vehicle having exhaust gas which may reach elevated
temperatures.
[0018] FIG. 1 illustrates a cross-sectional view of the exhaust
system 100 of the present invention. FIG. 1 illustrates a first
exhaust member 107 to conduct the exhaust and other heated fluids
to the atmosphere through a first exhaust output port 111 and a
second exhaust member 109 to conduct exhaust and other heated
fluids to the atmosphere through a second exhaust output port 113.
Although FIG. 1 illustrates a first exhaust member 107 and a second
exhaust member 109, the teachings of the present invention can be
extended to fewer or more exhaust members. The exhaust system 100
may include a blower member 101 to blow or pressurize fluid which
may be an ambient air or other appropriate fluids and which may be
supplied to a first blower output passageway which may be defined
by the first tube 103 and may be supplied to a second blower output
passageway which may be defined by the second tube 105. The first
tube 103 may be connected to the first exhaust member 107 at an
output port of the first tube 103 so that the pressurized fluid may
be mixed with the engine gases which are generated as result of the
combustion of the engine of the vehicle. The second tube 105 may be
connected to the second exhaust member 109 at an output port of the
second tube 105 so that the pressurized fluid may be mixed with the
engine gases which are generated as result of the combustion of the
engine of the vehicle.
[0019] The blower member 101 may include an electric motor to
provide the pressurized fluid which may be connected to the battery
of the vehicle (or from the vehicle's electrical system) or the
blower member 101 may be mechanically driven from any location of
the vehicle by the engine of the vehicle. The first exhaust member
107 and the second exhaust member 109 may be a single cylindrical
tube having the outer surface coated with chrome for decoration.
The first exhaust member 107 and the second exhaust member 109 may
have a cross-section such as a round, oval, square or other
appropriate shape.
[0020] In addition to the pressurized fluid, and the air fluid may
be connected to the first exhaust member 107 and the second exhaust
member 109 by forced airflow which may result from the operation
and speed of the vehicle from an air dam of the vehicle. This air
fluid is conducted to the first exhaust member 107 in a first air
dam passageway 119, and the air fluid may be conducted to the
second exhaust member 109 through the first air dam output port of
the third tube 115. The air fluid may be conducted to the first
exhaust member 107 by the fourth tube 117 in the second air dam
passageway 131 of the fourth tube 117 and the air fluid may be
conducted to the first exhaust member 107 through the first air dam
output port of the fourth tube 117.
[0021] The engine gases may be exhausted from the engine of the
vehicle and enters the first exhaust passageway of the first
exhaust member 107 and enters the second exhaust passageway of the
second exhaust member 109 and may be cooled as a result of mixing
with the pressurized fluid from the first blower output passageway
and the second lower output passageway. Furthermore, the engine
gases may be further cooled as a result of mixing with the air
fluid from the first air dam passageway and the second air dam
passageway. The cooled engine gases may be conducted along the
first exhaust member 107 and the second exhaust member 109 and may
be output to the atmosphere at the first exhaust output port 111
and the second exhaust output port 113. The blower member 101 may
include a sensor device to sense if the pressured fluid is backing
up and may indicate that the exhaust system 100 is not operating
properly. The sensor device may sense when the speed is sufficient
that the air fluid from the air dam is sufficient to cool the first
and second exhaust members 107, 109 so that the sensor may turn off
the blower member 101 when the speed has reached a predetermined
speed.
[0022] FIG. 1 additionally illustrates that the pressurized fluid
may be supplied by compressed air from container 151 through the
compressed air tube 153. Additionally the container 151 may have a
refrigeration device in order to cool the air below ambient
temperature. The refrigerated air may or may not be distributed by
the blower or blowers.
[0023] FIG. 2 illustrates a first blower 241 having a first output
tube 242 to output fluid and a second blower 243 having a second
output to 244 to output fluid. FIG. 2 additionally illustrates that
a refrigerant blower 245 has a third output tube 246 to output
refrigerated fluid
[0024] Turning now to FIG. 3, the blower 331 which may be a source
of compressed air, refrigerated air or ram air includes an output
tube 333 which may be positioned at an angled relationship to the
stream of fluid to prevent the air from being forced into the
exhaust such that the air would blow against the exhaust and may be
positioned downstream of the catalyst 335. The tube 333 with the
blower 331 may be inserted into the stream of fluid flow to create
a Venturi effect.
[0025] While the invention is susceptible to various modifications
and alternative forms, specific embodiments thereof have been shown
by way of example in the drawings and are herein described in
detail. It should be understood, however, that the description
herein of specific embodiments is not intended to limit the
invention to the particular forms disclosed.
