ABSTRACT:
A movable portion is movable from a closed position, in which the movable portion is in contact with a valve element, to an opened position so as to supply fuel from a fuel portion to a compression chamber through a fuel passage. A drive control unit supplies of a small driving current, which is sufficient to maintain the movable portion at the closed position, to a coil portion so as to move the movable portion from the opened position to the closed position. The drive control unit switches the supply of the small driving current to supply of the large driving current in the course of the movement of the movable portion to the closed position by supplying the small driving current.
