置。 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. a bypass control valve is disposed in the bypass passage, and the fuel injection amount is determined based on the amount of depression of the accelerator pedal and the engine speed,
Detection means for detecting an engine acceleration state in an air supply control device for a two-stroke internal combustion engine in which the opening degree of a bypass control valve is controlled according to a control signal level predetermined according to the amount of depression of an accelerator pedal and the engine speed. and a control means for temporarily changing the control signal level for controlling the opening degree of the bypass control valve in the direction of closing the bypass control valve with respect to the predetermined control signal level during engine acceleration operation. Air supply control device for a two-stroke internal combustion engine.
