摘要:
A drive circuit for driving an electromagnetic fuel-injection valve, the drive circuit varying an application sequence of a drive voltage, which is supplied from a step-up power supply to a fuel-injection valve for conducting injection multiple times in a single stroke of an internal-combustion engine, between the first injection and the second and subsequent injections, and setting the application sequence such that the consumption of power from the step-up power supply in the first injection becomes smaller than the power consumption in one of the second and subsequent injections.
