徴とするサブチャンバー付２サイクルエンジン。(1) A valve is interposed between the exhaust port of the 2-stroke engine and a subchamber connected to the exhaust port, and this valve is opened and closed in a predetermined rotation range of the engine via a valve opening/closing device to exhaust air. In a two-stroke engine with a sub-chamber that has a variable tube volume, the valve is a cylindrical valve with a communication hole formed on its circumference, and the valve opening/closing device applies centrifugal force to a ball rotating in conjunction with the crankshaft. It consists of a mechanical governor mechanism, a cam mechanism that converts the amount of movement in the thrust direction by the governor mechanism into the amount of rotation of the cam plate, and an interlocking means that transmits the amount of rotation of the cam plate to the cylindrical valve.
