An engine exhaust noise suppression system comprising a plurality of bypass ports surrounding the exhaust tailpipe and opening to the atmosphere to create streams of cool air which generate vortices effective to dampen the exhaust noise vibrations and to contain the same as they dissipate into the atmosphere. Fluid is injected into the air streams to enhance the vorticular action thereof by applying a helical swirling motion to the streams.
An exhaust noise suppression system for an internal combustion engine having an exhaust conduit open at one end to the atmosphere for discharging a stream of exhaust gases along a primary axis, which comprises means forming a plurality of ports equally spaced from each other around said conduit for conveying streams of air along respective secondary axes extending parallel to said primary axis, said ports each having an exhaust end terminating in a plane at least substantially coincident with said end of said conduit, said ports being equal in number, an...
