Abstract
Muffler assembly for an engine comprises an outer cylinder constituting a muffler body, an inner cylinder coaxially disposed in the outer cylinder, a connection cylinder disposed inside the inner cylinder having one end on an upstream side and another end on a downstream side, a partition plate disposed inside the inner cylinder at the downstream end of the connection cylinder, first and second silencer chambers formed at the upstream and the downstream end of the connection cylinder, respectively, an inlet, pipe through which an engine exhaust gas is introduced into the muffler body, and an outlet pipe having an upstream end disposed inside the inner cylinder and a downstream end opened outward of the muffler assembly. The connection cylinder has an upstream end portion in which a plurality of holes are circumferentially formed. The inlet pipe has a downstream end portion in which a plurality of holes are circumferentially formed so as to flow the exhaust gas passing from the inlet pipe into the first silencer chamber. The upstream end of the outlet pipe is plugged and coaxially inserted into the downstream end of the connection cylinder, the outlet pipe having an upstream end portion in which a plurality of holes are formed. An resonance chamber is formed so as to surround the outlet pipe at the downstream portion thereof.
