Title of Invention

A FUEL INJECTION METHOD FOR A FUEL INJECTION SYSTEM

Abstract During a normal operation, a detected current component, when a fuel-injecting solenoid drive current is turned off (step S11), is input to an A/D converter and this value is stored (step S12). Then, a drive current is turned on (step S13), and, after an elapse of a specified time (step S14), an input voltage to an A/D converter is detected (step S15). Then a current value (offset value) for a difference - an input voltage minus an offset voltage - is calculated (step S16), it is subjected to a current span adjustment by a span correction value (step S17), a pulse width current correction value is calculated (step S2a), and then a drive pulse width is calculated based on this pulse width current correction value (step S2b) and supplied to a solenoid. Accordingly, a fuel injection amount can be accurately corrected with an offset component, produced when a fuel-injecting solenoid current is detected, eliminated.
