摘要： PURPOSE: To control the fuel injection of high accuracy in metering by ensuring a target valve opening period even in the change of the fuel pressure in a fuel injection device of an internal combustion engine wherein a current-carrying stop timing to a solenoid coil for valve opening is prior to a current-carrying start timing to a solenoid coil for valve closing, to close a fuel injection hole simultaneously with the stop of the current-carrying to the solenoid coil for valve opening. CONSTITUTION: The rise starting period of a valve closing power produced by the solenoid coil for valve closing is delayed by shortening an overlap time in accordance with the increase of the fuel pressure supplied to the fuel injection device corresponding to an operating condition of the internal combustion engine.

摘要： A fuel injection apparatus (1) of an internal combustion engine includes a valve body (9) movably disposed for back and forth movement in a fuel passage (7) to open and close a fuel injection hole (8) of the fuel injection apparatus (1). An armature (10) is attached to the valve body (9). A valve-opening solenoid coil (13) drives the armature (10) in a valve-opening direction. A valve-closing solenoid coil (11) drives the armature (10) in a valve-closing direction. A controller that sets an overlap time, which is a time by which starting of electrifying of the valve-closing solenoid coil (11) precedes stopping of electrifying of the valve-opening solenoid coil (13), controls the solenoid coils in accordance with a fuel pressure supplied to the fuel injection apparatus (1) such that a valve-closing force on the valve body (9) does not exceed an open valve holding force on the valve body (9) prior to the time when stopping of the electrifying of the valve-opening solenoid (13) coil occurs.
