A fuel is injected based on the rpm of the engine and the suction air rate. The fuel injection amount is corrected depending on a map of fuel injection share correction coefficient prepared in advance and determined by data such as a throttle valve opening and the rpm of the engine so that amounts of fuel injected will be even at the respective cylinders. The fuel injection share correction coefficient is for correcting fuel deviation due to construction of suction passage to with the respective cylinders or for correcting fuel deviation due to arrangement of two injectors in one bore with respect to the throttle valve shaft.
