ABSTRACT:
An engine revolution in an expansion stroke of a cylinder is calculated, and stored, from a time that is required for a crank shaft to rotate by a predetermined angle from a compression upper dead center of that cylinder, and to determine the fuel injection amount, in averaging these stored revolutions from the cylinder immediately prior to a cylinder before the cylinder that is immediately prior to obtain a revolution that serves as the engine revolution, how many past cylinders are retroactively averaged is switched according to the engine operation state.
