摘要： An integral manifold-muffler-catalyst device (for an internal combustion engine having a plurality of combustion cylinders generating exhaust gases), comprising: (a) a monolithic catalyst having a plurality of aligned passages for effecting laminar flow of the exhaust gases therethrough while; (b) a high temperature resistant chamber assembly for close-coupling the catalyst to the engine having (i) an expansion chamber for substantially dissipating low frequency standing sound waves of said exhaust gases and for modifying high frequency sound waves of said exhaust gases and (ii) manifolding passages at one side of the expansion chamber for collecting and delivering the exhaust gases from the cylinders to the expansion chamber; and (c) means for effecting converging flow from said expansion chamber to and across substantially the full entrance face of said aligned passages, as well as from the catalyst, for effecting attenuation of high frequency sound waves carried by the exhaust gases.
