摘要：
A two stroke engine equipped with a mechanically driven supercharger in the intake passage downstream of throttle valve. A bypass air passage bypassing the supercharger is provided, and a bypass air control valve is arranged in the bypass air passage. When the engine is idling, the bypass air control valve is controlled so that the level of vacuum in the intake passage between the throttle valve and the supercharger is maintained at a constant value.
