PURPOSE:To prevent an engine from being ineffective during acceleration and to reduce the possibility of smoking a spark plug, by providing a compensating value computing means for computing a compensating amount in accordance with a variation in engine load, and a means for injecting fuel having a compensated basic fuel injection amount. CONSTITUTION:A control sensor receives signals from an air flowmeter 12, a throttle valve sensor 36, an engine rotational speed sensor 36, a water temperature sensor 54 and an oxygen sensor 48. This control unit 62 computes a compensating value in accordance with a variation in engine load which may be obtained from an intake-air volume per engine revolution. The amount of fuel which is obtained by compensating a basic fuel injection amount with the above- mentioned compensating value is injected. Thus, it is possible to prevent the engine from being ineffective during acceleration due to an overriched air-fuel ratio of the engine, thereby it is possible to reduce the possibility of smoking a spark plug.
