ABSTRACT:
A fuel injection control method for an internal combustion engine wherein synchronous fuel injection is effected in synchronism with control pulses generated at predetermined crank angle positions of the engine corresponding to suction strokes of respective engine cylinders to supply the engine with a quantity of fuel required for operating conditions of the engine, and when the engine is operating in a predetermined acceleration condition, asynchronous fuel injection is effected independently of the above control pulses to supply the engine with an additional quantity of fuel. The quantity of fuel to be supplied by the synchronous fuel injection is decreased by a predetermined amount immediately after the asynchronous fuel injection is effected. The predetermined amount of fuel corresponds to the quantity of fuel to be supplied by the asynchronous fuel injection.
