Abstract

PURPOSE: To reduce cost when purifying exhaust gases by connecting a catalytic convertor to the outlet of an exhaust manifold and by offering a dual silencer so as to muffle exhaust noises more easily.
CONSTITUTION: A catalytic convertor 4 is housed in an exhaust manifold 3 which is attached to an engine 2. Two exhaust silencers S1 and S2 are provided in the downstream immediately following the convertor 4. Sound waves emerged from the engine 2 must first go through a common silencer so as to prevent drops in sound frequencies. The sound waves must then go through two silencers, i.e., the exhaust noises are effectively dampened. The design provides a more effective method of muffling exhaust noises without giving rise to back pressure and helps reduce the cost through use of a single catalytic converter.
