초록

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...
