摘要: When voltage changes occur in the battery used as a power supply in a fuel injection system, the amount of fuel injection also changes and the required amount of fuel injected cannot be obtained. To eliminate this problem, a fuel injector system is provided which has a fuel injection valve with at least one coil, a power supply, a power supply voltage detector, and a control unit for controlling the fuel injection valve. The control unit sets a reference value of a power supply voltages, and the above-mentioned fuel injection valve is controlled so as to obtain the required ampere-turns by reducing the resultant inductance of the coil when a power supply voltage detection value is less than the above-mentioned reference value, and the resultant inductance of the coil is increased when the power voltage detection value is greater than the reference value.

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: 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.
