    摘要： A fuel-injection valve includes a fuel-injection hole, a valve element and a valve seat for opening and closing the fuel-injection hole, a force-applying member for applying force to the valve element in a direction of motion of the valve element, and a drive unit for applying force to the valve element in the direction opposite to that of the force applied by the force-applying member; wherein a secondary oscillation system, which interacts with a primary oscillation system including the valve element and the force-applying member, is added to the primary oscillation system, and the phase angle of force applied to the primary oscillation system by the secondary oscillation system is also staggered from that of force applied to the primary oscillation system, which is other than the force applied to the primary oscillation system by the secondary oscillation system, whereby the bouncing of the valve element during opening and closing of the valve is reduced, which in turn makes it possible to achieve very accurate fuel-injection control.

    摘要： In a fuel injection device, a driving unit structure has a magnetic aperture, in which an inner diameter is gradually enlarged toward the mover side, provided in an inner peripheral surface of the magnetic core. It is possible to reduce magnetic delay time upon valve opening from the supply of the electric current to the coil to the rise of magnetic flux and magnetic delay time upon valve closing from the stoppage of the electric current to the coil to reduction of magnetic flux, by providing a magnetic aperture in the inner peripheral surface of the magnetic core. Thus it is possible to improve the dynamic responsiveness upon valve opening and valve closing.

    摘要： The drive device is configured to, during a time interval between an earlier fuel injection (first fuel injection) and a later fuel injection (second fuel injection), supply an electromagnetic coil with an intermediate current at a voltage with a level of not opening the valve. Further, the drive device sets a voltage application for supplying the intermediate current to initiate before a valve closing in the earlier fuel injection and terminate before half a period of time between a first instant when the valve is closed in the earlier fuel injection and a second instant when a supply of a drive current for opening the valve is initiated in the later fuel injection.
