Abstract
A method for driving an injector for feeding an internal combustion engine with fuel which is capable of improving starting characteristics of the engine. A power circuit is provided which functions to charge a power capacitor utilizing an output of a generating coil, so that feeding of an injection command signal permits a driving current to flow through a driving coil of an injector. A period of time required to permit charges in an amount necessary to drive the injector to be accumulated in the power capacitor is defined to be an injector drive prohibition period, during which generation of the injection command signal is prohibited, to thereby prohibit flowing of the driving current. The injector drive prohibition period is elapsed, so that a required amount of charges are accumulated in the power capacitor, followed by generation of the injection command signal, to thereby permit the driving current to flow the driving coil.
