める制御手段とを具備する２サイクル内燃機関。 A mechanical supercharger is arranged in an engine air supply passage, a bypass passage is branched from an air supply passage downstream of the mechanical turbocharger, and the bypass passage is connected to an air supply passage upstream of the mechanical turbocharger. In a two-stroke internal combustion engine in which a bypass control valve is arranged in the bypass passage, and the fuel injection amount and the opening degree of the bypass control valve are determined based on the amount of depression of the accelerator pedal and the engine speed, the engine acceleration state and a control means that temporarily reduces the fuel injection amount to the fuel injection amount determined based on the amount of depression of the accelerator pedal and the engine speed during engine acceleration operation. Internal combustion engine.
