    • In a diesel engine controlling system having a fuel injection pump, a fuel injection timing adjusting device is controlled by a drive pulse signal whose duty cycle is controlled by a microcomputer. The duty cycle is determined such that a basic duty cycle obtained by using engine rotational speed and injection quantity, is modified or corrected by way of a correction factor and a forecast correction factor. The-first mentioned correction factor comprises an integration component and a proportional component both derived from the difference between a measured fuel injection or ignition timing and a desired or reference fuel injection or ignition timing, which is calculated by using the engine rotational speed and the injection quantity. The forecast correction factor corresponds to a differential value of the basic duty cycle or the desired fuel injection or ignition timing. In order to detect the fuel injection or ignition timing a timing detector is employed, where the state of an output signal from the detector is monitored to prohibit calculation of the difference or error, thereby correcting the basic duty cycle by only the forecast correction factor when the detector is in abnormal condition.
    • 在具有燃料喷射泵的柴油机控制系统中,燃料喷射正时调整装置由其微计算机控制占空比的驱动脉冲信号来控制。 确定占空比,使得通过使用发动机转速和喷射量获得的基本占空比通过校正因子和预测校正因子进行修改或校正。 首先提到的校正因子包括积分分量和比例分量,两者都是根据测量的燃料喷射或点火正时与通过使用发动机转速和喷射计算的所需或参考燃料喷射或点火正时之间的差导出的 数量。 预测校正因子对应于基本占空比或期望的燃料喷射或点火正时的差分值。 为了检测燃料喷射或点火正时,采用定时检测器,其中来自检测器的输出信号的状态被监视以禁止差异或误差的计算,从而仅通过预测校正因子来校正基本占空比 检测器处于异常状态。

    • Disclosed is a fuel injection quantity control system incorporated with a fuel injection pump with a solenoid-operated spill valve wherein a control signal is generated for cutting off a fuel supply to engine cylinders when a rotational phase angle of a drive shaft of the fuel injection pump is coincident with a desired spill phase angle determined in accordance with engine operating conditions. The desired spill phase angle, i.e., the opening timing of the spill valve is controlled in accordance with the rotational variations of the fuel injection pump. The desired spill phase angle is divided by unit angle corresponding to a detection period of rotational angle signals produced in accordance with the rotation of the pump drive shaft, obtaining a quotient and a remainder angle. The remainder angle is converted into a time on the basis of an engine speed. The generation of the control signal basically occurs upon the elapse of the converted time after the count of rotational angle signals is coincident with the quotient. If the engine operating condition varies immediately prior to the coincidence therebetween, the control signal is generated immediately after the coincidence or upon the elapse of a predetermined time period thereafter.
    • 公开了一种燃料喷射量控制系统,其结合有具有电磁式溢流阀的燃料喷射泵,其中当燃料喷射泵的驱动轴的旋转相位角被产生时,产生用于切断对发动机气缸的燃料供给的控制信号 与根据发动机操作条件确定的期望的溢流相位角一致。 根据燃料喷射泵的旋转变化来控制溢流相位角,即溢流阀的打开正时。 将期望的溢出相位角除以与根据泵驱动轴的旋转产生的旋转角度信号的检测周期相对应的单位角度,获得商和余数角。 剩余角度根据发动机转速转换为时间。 控制信号的产生基本上是在旋转角度信号的计数与商一致后转换的时间经过的。 如果发动机工作条件在它们之间立即变化,则在重合之后立即或在其之后的预定时间段之后立即产生控制信号。
