摘要： A muffler for an internal combustion engine is disclosed which is capable of effectively enhancing its muffling effect without any substantial increase in size, weight or manufacturing cost. The exhaust gas ejected from an exhaust port of the internal combustion engine is divided in the muffler into at least two flows. The divided exhaust gas flows are subsequently impinged against each other before the divided exhaust gas flows are finally discharged from a final exhaust port to the external atmosphere. More specifically, this muffler comprises an expansion chamber into which the exhaust gas is to be introduced from the exhaust port, and the expansion chamber is provided with at least two impingement openings for enabling the exhaust gas to be divided into at least two exhaust gas flows which are designed to be subsequently impinged against each other.
