Title: MUFFLER ASSEMBLY
Abstract:
The invention provides a muffler assembly (10) for exhaust gas flow communication with an engine exhaust. The assembly (10) includes a muffler (12) having inlet and outlet ports (14, 16). The assembly (10) also includes first and second flow of passages in common fluid communication with the outlet port (16) and in variable fluid communication with the inlet port (14). The first and second flow passages meet at first and second connecting points. The first connecting point is located in the proximity of the inlet port (14). The first flow passage has a higher resistance to fluid flow than the second flow passage. The assembly (10) also includes a valve means (24) generally located past the first connecting point inside the second flow passage for selectively proportionating exhaust gases passing through the passages. The first flow passage includes three or more conduits (26, 28, 30) being in fluid communication with each other.
