エンジン。[Claims for Utility Model Registration] (1) A device having an intake valve and an exhaust valve, a mechanical supercharger provided in the intake passage, a bypass passage bypassing the mechanical supercharger, and a computer installed in the bypass passage. In a two-stroke engine in which the amount of supercharging is controlled by providing a bypass valve whose opening and closing is controlled by A two-stroke engine with a mechanical supercharger, characterized in that the opening/closing timing of the engine is set such that the intake valve opens after the exhaust valve opens, and the intake valve closes after the exhaust valve closes. (2) The two-stroke engine with a mechanical supercharger according to claim 1, wherein the opening degree of the bypass valve is continuously controlled according to the engine load.
