ABSTRACT:
A method of controlling fuel injection to an internal combustion engine by electronic circuits. A plurality of cylinders installed in the internal combustion engine are divided into two groups and two electronic circuits for controlling the respective two cylinder groups are provided. By comparing between the outputs of the two electronic circuits, whether the operations of the respective electronic circuits are normal or not is judged. The fuel injection controlled by the electronic circuit which has been judged to be abnormal is stopped, while the fuel injection controlled by the electronic circuit which has been judged to be normal is continued. Thus, the internal combustion engine is driven solely by one group of cylinders.
