ABSTRACT:
A fuel injection injector controller comprises high voltage generation means for stepping up voltage based on electric power from a power supply to generate a voltage higher than the power supply, first switching means being disposed on a power supply passage from the high voltage generation means to an injector for conducting when a valve of the injector is opened upon reception of a drive signal, negative voltage generation means for generating a negative-polarity voltage, and second switching means being disposed on a power supply passage from the negative voltage generation means to the injector for conducting when the valve of the injector is closed upon reception of the drive signal.
