Fuel injection control method for internal combustion engines at acceleration
A method is described of controlling the injection of fuel into an internal combustion engine having cylinders. The 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 one of the cylinders to supply each of the cylinders with a quantity of fuel required for operating conditions of the engine, and when the engine is operating in a predetermined accelerating condition. Asynchronous fuel injection is effected independently of the control pulses to supply each of the cylinders with an additional quantity of fuel. The method consists of the step of decreasing and quantity of fuel to be supplied to the engine by the synchronous fuel injection, by a predetermined amount corresponding to the quantity of fuel to be supplied by the asynchronous fuel injection, immediately after the asynchronous fuel injection is effected.
