Abstract
A fuel injection apparatus has two magnetic coils, a valve-opening magnetic coil and a valve-closing magnetic coil. During the valve opening operation the magnetic force caused by the valve opening magnetic coil moves the movable armature toward the opening position for discharging the fuel into the engine and during the valve closing operation the magnetic force caused by the valve-closing magnetic coil moves the movable armature to the closing position for stopping the fuel injection, so that the response time of the fuel injection apparatus is shortened.
