摘要： A fuel injection control apparatus is capable of reducing a minimum quantity of fuel injection without reducing a maximum quantity of injection. To open a fuel injector valve, a driving circuit supplies an electric current from a high-voltage power supply to the fuel injector. Then, after valve opening, the high-voltage power supply is switched to a low-voltage power supply, and an open state of the valve is retained. For opening the valve of the fuel injector, a microcomputer, after supplying current from the high-voltage power supply to the injector, discharges the current rapidly for a decrease below a first current level at which the open state of the valve cannot be retained. The microcomputer then controls the supply current to the injector so as to supply a current at a second current level at which the open state of the valve can be retained.

摘要： A fuel injection control apparatus includes a computing unit that calculates a pulse width for a pulse signal which drives the valve of a fuel injector, based on the operational state of the internal combustion engine and fuel pressure detected by a fuel pressure sensor. After a valve-opening command has turned on and a high valve-opening current has been supplied to open the fuel injector valve, a fuel injector driving signal waveform command unit discharges the current and supplies a small hold current Ih2 to maintain the injector's valve-open state. After the elapse of a predetermined rapid-discharge starting time from the turn-on of the valve-opening command, the fuel injector driving signal waveform command unit rapidly discharges the current until the hold current Ih2 has been reached.
