PURPOSE: To improve the starting property of an engine by conducting a fuel cut when a throttle divergence exceeding a determined value is detected in the starting, and prohibiting the fuel cut when a particular state shifting to a fuel supply shortage is detected.
CONSTITUTION: In the starting of an engine, a preliminarily set fuel is injected through a fuel injection valve 27, but when the divergence of a throttle valve 25 exceeding a determined value is detected, a fuel cut is conducted in the fuel injection valve 27. In such a case as the transition to a fuel supply shortage, for example, when an inlet temperature exceeding a determined value or the detected value of a sensor 32 without a determined range is detected, the fuel cut is prohibited, and the normal fuel supply in the starting is conducted to the fuel injection valve 27. Hence, the starting recording to the conditions can be carried out to improve the starting property of the engine.
