摘要:
An exhaust muffler device for an internal combustion engine includes an outer housing (2) which defines a sealed chamber (21) and which is connected to opposite inlet and outlet pipes (5, 6), and an initial expansion subchamber (31) and a pre-outlet subchamber (32) disposed in the sealed chamber (21) . The exhaust gas enters the initial expansion subchamber (31) and mainly flows to a tubular passage (321) in the pre-outlet subchamber (32) to be exhausted through the outlet pipe (6). Portion of the exhaust gas flows into the sealed chamber (21) and re-enters into a rejoining region (321b) of the tubular passage (321) to be entrained in the main stream, thereby attenuating noise of the engine with minimal reduction of engine performance.
