MUFFLERS WITH ENHANCED ACOUSTIC PERFORMANCE AT LOW AND MODERATE FREQUENCIES

摘要

The invention relates to an exhaust silencer of muffler for an internal combustion engine, in particular a silencer with the damping characteristics of a resonator with the absorptive characteristics of a dissipative silencer. The silencer (500) of the present invention provides an improved silencer of muffler for use with an internal combustion engine that incorporates both a dissipative silencer (510) and a resonator (520) in a single muffler assembly suitable for use with standard automotive construction techniques.
