초록

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.
