ABSTRACT:
A muffler for a two-stroke internal combustion engine has an expansion chamber into which a rush of exhaust gas is introduced from the engine. In the vicinity of an exhaust gas inlet from the engine into the expansion chamber, the muffler has an external air intake for external air to be suctionally introduced into the expansion chamber by the rush of exhaust gas. With the external air introduced, carbon monoxide (CO) emission into the ambient is reduced.
