摘要： 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.
摘要翻译：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。
