Abstract

A method of controlling fuel injection in an engine and an apparatus therefor, wherein a basic fuel injection quantity is determined based on the intake air flow rate of the engine and the RPM of the engine, and the basic fuel injection quantity thus determined is corrected by a correcting value commensurate to the accelerating or decelerating condition of the engine. Said correcting value corresponds to a value commensurate to a transitional fluctuating value detected which is further corrected commensurate to the RPM of the engine until the transitional fluctuating value during the accelerating or decelerating condition of the engine reaches the peak value, and to a value to be decreased from the peak value at a predetermined time constant which is further corrected commensurate to the RPM of the engine after the transitional fluctuating value has reached the peak value.
