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.

摘要： In a drive unit of a fuel injection device, an electric current is supplied to the fuel injection device by applying a high voltage to the fuel injection device from a high voltage source whose voltage is boosted to a voltage higher than a battery voltage at the time of opening a valve of the fuel injection device. Thereafter, the electric current supplied to the fuel injection device is lowered to a current value at which a valve element cannot be held in a valve open state by stopping the applying of the high voltage from the high voltage source. Thereafter, in a stage where a supply current is switched to a hold current, another high voltage is applied to the fuel injection device from the high voltage source.

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： Improving the injection fuel mass accuracy of fuel injector, it is necessary to make the fuel injector perform seat valve opening and closing operation quickly. When the shapes of a fixed core and an anchor are optimized to improve the responsiveness of a magnetic flux, it is necessary to ensure a sufficient fuel path area while preventing adhesion by making the adherence phenomenon rarely occur between an end face of the anchor and an end face of the fixed core. A through hole passes through an anchor forming an armature of an electromagnetic fuel injector from a face of the anchor where the anchor faces a fixed core to a back face where the through hole has a large-diameter portion and a small-diameter portion, and the large-diameter portion is located in an upstream part and is offset to the outer periphery with respect to the small-diameter portion.
