ABSTRACT:
In a method of computing and controlling the fuel injection quantity of a fuel injection system and the ignition timing of an ignition system of an international combustion engine by a microcomputer in accordance with operating conditions of the engine, a discrimination signal indicative of the presence or absence of misfiring is generated in accordance with an electric signal from the ignition system so that when misfiring occurs, even if fuel injection quantity data has already been computed, data for reducing the fuel injection quantity to zero is generated in response to the discrimination signal to stop fuel injection.
