Internal combustion engine fuel injection apparatus and control method thereof |
摘要 |
A fuel injection apparatus of an internal combustion engine includes a valve body movably disposed for back and forth movement in a fuel passage to open and close a fuel injection hole of the fuel injection apparatus. An armature is attached to the valve body. A valve-opening solenoid coil drives the armature in a valve-opening direction. A valve-closing solenoid coil drives the armature 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 precedes stopping of electrifying of the valve-opening solenoid coil, controls the solenoid coils in accordance with a fuel pressure supplied to the fuel injection apparatus such that a valve-closing force on the valve body does not exceed an open valve holding force on the valve body prior to the time when stopping of the electrifying of the valve-opening solenoid coil occurs.
