Abstract
A method of controlling the timing of fuel injection in an internal combustion engine, wherein the injection timing of each of a plurality of fuel injection valves provided respectively for as many cylinders is determined in response to engine operating conditions. When it is determined that the engine is in a first predetermined operating condition, fuel is injected into a cylinder that corresponds to the present pulse of a control signal upon generation of same. The control signal is generated at a predetermined crank angle before a top dead center of each cylinder at the start of the intake stroke in the cylinder. When the engine is in a second predetermined operating condition, fuel is injected into another cylinder that corresponds to a pulse of the control signal next to the present pulse, upon generation of the present pulse. Preferably, the first and second predetermined operating conditions are determined by the engine rotational speed and/or the engine temperature.
