Abstract
A muffler for a two-stroke internal combustion engine includes an expansion chamber into which exhaust gas ejected from the exhaust port of the engine is introduced. An air-supplying device is adapted to supply outside air to the expansion chamber. The air-supplying device is actuated by taking advantage of the pressure pulsation in the crank case of the engine, and is constituted by a diaphragm pump.
