    摘要： The present invention provides a simplified fuel injector which uses fuel as hydraulic oil to intensify the injection pressure.A pressure intensifier of the fuel injector is provided with a pressurization piston 106, a first fuel chamber 107 that communicates with a fuel inlet passage 101 (or a fuel supply passage), and a fuel pressurization chamber 111. The pressurization chamber 111 is provided inside a valve body 110. The pressurization piston 106 is formed displaceably relative to the valve body 110 and is provided with a first pressure receiving surface 106a and a pressurization piston portion 106b. The first pressure receiving surface 106a is one end surface of the pressurization piston 106 which faces one of the piston displacement directions 106d, that is, faces the first fuel chamber 107. The pressurization piston portion 106b is provided on the other end surface of the piston 106 which faces the other direction of the piston displacement directions 106d, that is, faces the pressurization chamber 111. The area of the pressurization piston portion 106b which faces the pressurization chamber 111 is smaller than that of the first pressure receiving surface 106a, and the pressurization piston portion 106b serves to change the volume of the pressurization chamber 111.

    摘要： An electromagnetic fuel injection valve device for an internal combustion engine is configured to carry out an energization to an electromagnetic coil of an injection valve actuator for a valve opening motion and additionally carry out a mid-term energization at a time interval between both an energization for valve opening of a previous fuel injection and an energization for valve opening of a subsequent fuel injection. A current of the mid-term energization is smaller than a current of the energization for valve opening motion and has the same direction as a direction of the current of the energization for valve opening motion.

    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.
