ルエンジンの排気通路。 In the exhaust passage of a two-cycle engine, the upstream end of the valve housing pipe is connected to the downstream end of the exhaust hole that penetrates the cylinder, and the upstream end of the valve housing pipe incorporating the exhaust valve is connected to the downstream end of the exhaust pipe. An extension pipe extending to the upstream side is provided on the connection surface of the exhaust hole, and a wide expanded part with a step is provided on the downstream side of the exhaust hole so that a cylindrical gap is formed between the two. An exhaust passage for a two-cycle engine, characterized in that a heat insulating gasket is interposed between the upstream end and the stepped portion and at the connection surface between the exhaust hole and the valve housing pipe.
