Abstract
A method and apparatus for controlling the injection of fuel into an internal combustion engine having a plurality of unit injectors which are each controllable separately for each cylinder of the engine. The occurrence of a malfunction in the fuel injection of each of the injectors is discriminated in accordance with the engine operating condition detected by sensors whereby when the presence of a malfunction in the injector of any one of the cylinders is discriminated, the operation of the engine is not stopped but the operation is continued in a fault mode of operation so that the injection of fuel from the malfunctioning injector is stopped and the injection of fuel from the injector of at least one of the other cylinders is stopped or its number of events of injection is decreased from the standpoint of balance in the generation of engine power output.
