Abstract
An exhaust muffler for a two-cycle opposed cylinder engine of simultaneous ignition type having two cylinders opposing to each other in the horizontal direction. The muffler has conical members disposed to oppose to exhaust ports of the cylinders, the exhaust ports being arranged in a side-by-side relation. The conical members form conical annular discharge passages leading from respective exhaust ports. The discharge passages have flattened peripheral outlets of different opening areas. The flows of the exhaust gas from respective cylinders are introduced through the flattened peripheral outlets of the discharge passages into a common diffusion chamber, so that the attenuation of the pressure waves and release of heat of exhaust gas are promoted to reduce the exhaust noise of the engine.
