Internal combustion engine fuel injection apparatus and control method thereof

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.
