Abstract

A method and device for fuel injection, with which an adequate amount of fuel can be injected in accordance with a fuel injection amount required from an engine. A coil current is measured at one or plural time points at which a predetermined time after the start of fuel injection solenoid drive has been reached, and the time to stop the solenoid drive is corrected for adjustment based on the measured coil current value. The correction is made according to a correction value determined based on the measured coil current value and on the required fuel injection amount for the solenoid or according to a correction value selected from predetermined values for various combinations of measured coil current values and required fuel injection amounts, the selection being made in accordance with the combination of the measured coil current value and the required fuel injection amount.
