Abstract
After an injector current for opening a fuel injector is fed thereto, energization on the fuel injector is stopped to reduce the injector current towards a holding current level for keeping the fuel injector at an open state, a flywheel circuit being inoperative. Before a closed loop for controlling the injector current at the holding current level is formed, the flywheel circuit is made operative, whereby an influence of the operational delay of a circuit forming the closed loop can be reduced and further the injector current can be swiftly transferred to the holding current level before it falls largely.
