Description
FIELD OF THE INVENTION
[0001] The present invention relates to mufflers and more
particularly to a tunable muffler.
BACKGROUND
[0002] Most vehicles include a muffler to control the back pressure
on the engine and to control the noise from the engine. Both
functions are determined by the internal characteristics of the
muffler. These internal characteristics may be controlled by
baffles within the muffler, and these baffles have been generally
placed into the muffler when the muffler has been manufactured.
These baffles are not movable, and the characteristics remained
fixed. It would be desirable to be able to change the
characteristics of the muffler in order to more finely tune the
operation of the motor.
SUMMARY
[0003] A tunable muffler for a vehicle may include a center frame
having a first cavity, a detachable connected base plate being
detachably connected to the center frame and a tunable baffle to
tune the muffler.
[0004] The center frame may include a second cavity, and the
tunable baffle may be mounted substantially 90.degree. to the plane
of the base plate.
[0005] The baffle may be mounted substantially parallel to the
plane of the base plate, and the baffle may be controlled by a
control device.
