Patent
·
OSTI ID:6905755
This patent describes a pulsed catalytic converter supercharger silencer for an internal combustion engine. It comprises: an internal combustion engine having an air intake manifold and an exhaust manifold, a generally cylindrical rotating member adapted to rotate about its cylindrical axis; an air intake end, an exhaust gas end, and a plurality of closely spaced conduits disposed parallel to the axis of rotation of the cylindrical member fluidly communicating the air intake end with the exhaust gas end, the closely spaced conduits defining wave guides having dimensions sufficient to substantially attenuate sound waves about 1,000 Hz.
