    摘要： A heating time period is decreased by that a valve body including a hollow valve shaft is arranged in a slidable manner in a cylindrical part of a casing on which a nozzle body with a valve seat is mounted at a front end thereof, a fuel is introduced from a fuel outlet port opening on a shaft wall of the valve shaft into a fuel path formed by the valve shaft and the cylindrical part, the fuel is heated to be injected from the nozzle body by a heater arranged at an outside of the fuel path of the cylindrical part, and a sleeve is mounted in the fuel path so that a large diameter part thereof closes the fuel path at an upper area of the fuel outlet port, while a fuel inlet port is formed on a small diameter part of the sleeve to introduce the fuel into the fuel path, so that the fuel path is narrowed to decrease an amount of the fuel to be heated by the heater.

    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.

    摘要： A fuel system component for a direct injection internal combustion engine. The component includes a fuel rail and a plurality of direct injection fuel injectors which are rigidly attached to the rail. Each fuel injector has an elongated body as well as a harness assembly extending laterally outward from the elongated body. Each injector is attached to the fuel rail such that, when viewed along an axis of the fuel injector body, the fuel rail overlies at least a portion of the injector body and at least a portion of the harness assembly.
