A compact, sound-attenuating muffler for an internal combustion engine or the like. The muffler has a divergently tapered partition located near the inlet of the muffler for dividing the exhaust gases into two pulse streams with similar sound frequencies to achieve sound attenuation when the streams are converged back together. The diverging partition creates a low-pressure volume or region on the partition's downstream side where unignited fuels may accumulate. The partition is formed with a passageway to provide communication of live fire from the inlet of the muffler to the low-pressure volume for ignition of any unignited fuel. A method of communication of live fire from the inlet of the muffler to the low-pressure volume on the downstream side of the diverging partition in the muffler also is described. |
