摘要： Information storage element 102 and transmitter-receiver 103 are molded in resin connector part 101 of fuel injection valve 100 which projects outside of the engine by molding. The precise control of an injection amount is enabled by using directly the characteristic of injection amount stored in information storage element 102, and obtaining the width of the injection command pulse corresponding to the injection amount instruction value. Thereby, the minimum injection amount which is the minimum value of the fuel supply amount which can be controlled is reduced.

摘要： An injector driving control apparatus operates with minimum power consumption, while ensuring linearity (proportionality between the current supply duration and fuel injection volume of the injector) in a wide fuel pressure range. A coil current feedback circuit is provided for controlling the current feedback duration according to the fuel pressure after applying the current at a boost voltage. This enables optimal control of the injector, and, hence, an improvement in the fuel injection volume characteristics (linearity) and a reduction in the heat generated in the injector driving control circuits.

摘要： At an outlet portion of an injection hole (8) of a fuel injection valve (1), through removal of a part (A1, 7B) of a wall forming the injection hole (8), a restriction to a spray flow is eliminated, thereby, a deflection of the spray occurs in which the spray is rich at the side where this restriction is released and is lean at the side that is restricted. Thus, the ignition property of an internal combustion engine is improved, and an optimum spray is realized which reduces the amount of unburnt gas components being exhausted.

摘要： Provided is an electromagnetic fuel injection valve such that the collision faces of a chrome-coated movable element with respect to a stationary core and a valve body are flat, and change in the fuel injection quantity can be suppressed. The electromagnetic fuel injection valve is provided with a movable element having a cylindrical structure, and a valve body which is separated from the movable element and provided on the hollow portion side of the movable element so as to reciprocate. The movable element has a first collision face which collides with an end face of a stationary core, and a second collision face which collides with an end face of the valve body, said first collision face and second collision face coated with a chrome coating layer, and said chrome coating layer applied by disposing a positive electrode on the center axis of the movable element. An inclined face having an inclination to compensate for the inclination of the inclined face obtained from the thickness of the chrome coating layer gradually increasing toward the center axis is formed on the end face of the base material of the movable element on which at least one of either the first collision face or the second collision face will be formed. The chrome coating layer is applied on the inclined face, so that at least one of either the first collision face or the second collision face is flat.

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.
