摘要： A high-performance exhaust silencer in which a shell wall includes a shell outer plate, a shell inner plate, and a damping material to be inserted therebetween. A space between the shell outer plate and shell inner plate of the exhaust silencer is narrowed and the shell outer plate and the shell inner plate will not interfere with each other. An outer shape of the exhaust silencer is small but the expansion chambers are large by providing an air space between the shell outer plate and the shell inner plate. For the above-mentioned damping material, a material obtained by stretchably weaving metal wire into mesh is used.

摘要： An exhaust apparatus for a vehicle includes a spark arrester having a tubular spark arrester body assembled on a rear portion of a muffler connected to an exhaust pipe. A tail pipe is inserted in the spark arrester body and is mounted on the spark arrester such that exhaust gas flowing through the muffler is discharged into the atmospheric air from the tail pipe through the spark arrester, to carry out, expansion and contraction of exhaust gas in the spark arrester occurs to augment the sound reduction performance. An annular partition plate cooperates with an inner face of a spark arrester body to form a throttle path therebetween that is securely mounted on a tail pipe wherein a plurality of expansion chambers that communicate with each other through the throttle path are formed between the tail pipe and the spark arrester body with the annular partition plate disposed therebetween.
