    • A common rail fuel injection system for controlling the opening area of the fuel metering valve inserted in the fuel supply passage for supplying the fuel to the fuel injection pump to control, to a target pressure, fuel pressure in the common rail which holds the fuel delivered from the fuel injection pump. In the steady-state operation, the solenoid current is controlled by duty control at control frequency preset with an importance placed on the control stability. After determining the transient of control from the amount of change in the target common rail pressure which is a target of control, the control frequency is changed to a lower low frequency for a specific time until the common rail pressure reaches the target pressure. As a result, the valve body moves fast, thereby gaining a high control response despite of unsteady behavior of the valve body of the metering valve.

    • A fuel injection apparatus for an internal combustion engine is provided which is designed to control a fuel discharge from a fuel injection pump by regulating the quantity of fuel sucked into the fuel injection pump. The fuel injection pump is driven in synchronism with rotation of the engine to pressurize and supply the fuel to an accumulator chamber from which the fuel is injected into cylinders of the engine. The solenoid valve moves a valve member linearly to open and close a fluid path leading to the fuel injection pump. The controller actuates the solenoid valve in one of a first control mode when the engine speed is low and a second control mode when the engine speed is high. In the first control mode, a valve on-duration in which the solenoid valve is turned on to open the fluid path through the valve member and an area of the fluid path opened by the valve member are both controlled. In the second control mode, only the opened area of the fluid path is controlled. This achieves fine adjustment of quantity of fuel discharged from the fuel injection pump over a wide range of engine speeds.
    • 提供了一种用于内燃机的燃料喷射装置,其被设计成通过调节吸入燃料喷射泵的燃料量来控制来自燃料喷射泵的燃料排放。 燃料喷射泵与发动机的旋转同步地驱动,以将燃料加压和供给到蓄能室,燃料从该腔室喷射到发动机的气缸中。 电磁阀线性地移动阀构件以打开和关闭通向燃料喷射泵的流体路径。 当发动机转速低时,控制器以第一控制模式中的一个启动电磁阀,当发动机转速高时,控制器启动第二控制模式。 在第一控制模式中,控制电磁阀打开以打开通过阀构件的流体路径的阀持续时间和由阀构件打开的流体路径的区域。 在第二控制模式中,仅控制流体路径的打开区域。 这实现了在大范围的发动机转速下从燃料喷射泵排出的燃料量的微调。
