摘要： A high-pressure fuel accumulator for a fuel injection system of an internal combustion engine, in particular for a common-rail fuel injection system, has an elongated base body having an accumulator space for high-pressure fuel extending in the longitudinal direction of the base body, communicating with multiple connecting bores. A relief space connected to a low-pressure connection is provided in the base body, with a drain channel from the accumulator space opening into it. A pressure regulating valve is installed in the base body for opening and closing the drain channel.

摘要： Based on the output signal of the fuel sensor, it is judged whether or not the fuel (liquid fuel) is detected in the high pressure fuel system. When the fuel is detected, the count value for counting the detecting time is compared with the predetermined value. If the count value is equal to or larger than the predetermined value, the electromagnetic type high pressure fuel regulator is rendered closed and the starter motor prohibition flag is cleared to admit energizing the starter motor. As a result of this, the engine is permitted to be started and thus the high pressure fuel pump starts to produce the high pressure in the high pressure fuel system, whereby a sticking or a scuffing in the fuel pump due to poor lubrication can be prevented and an overshoot of the fuel pressure or a void injection in the fuel injector can be avoided.
摘要翻译：基于燃料传感器的输出信号，判断在高压燃料系统中是否检测到燃料（液体燃料）。当检测到燃料时，将用于计数检测时间的计数值与预定值进行比较。如果计数值等于或大于预定值，则使电磁式高压燃料调节器闭合，并且起动器电动机禁止标志被清除以允许起动电动机通电。结果，允许发动机起动，因此高压燃料泵开始在高压燃料系统中产生高压，从而可以防止由于润滑不良导致燃料泵中的粘着或磨损并且可以避免燃料压力的过冲或燃料喷射器中的空穴注入。

摘要： An object is to suppress cavitation generated at a distal end portion of a seat face when a valve body and a seat portion collide with each other. In a relief valve of a fuel pump, an intersection between the seat face and a flow channel hole is formed at a position more distant than the seat portion formed of the valve body in a valve closing state and the seat face in order to suppress generation of cavitation bubbles when the valve body improves and releases high-pressure fuel.

摘要： A fuel-injection system comprises a control unit that controls the injection of a fuel cylinder of an engine such that an injection volume of the fuel is injected into one of the cylinders during each work cycle of the engine. To this end, the control unit actuates an inlet valve and/or outlet valve such that, during pump strokes of a high-pressure pump which follow one another, a different high-pressure volume of the fuel per pump stroke is delivered into a pressure accumulator during at least two consecutive work cycles. The high-pressure volume that is produced per work cycle corresponds to the injection volume that is removed from the pressure accumulator per work cycle and is constant during each of the consecutive work cycles.

摘要： In the start mode of a fuel supply apparatus, a subtraction value of an electric power is obtained in view of an SCV characteristic. Furthermore, a common correction value is employed as the subtraction value in order to increase an actual fuel discharge amount when the internal combustion engine is started, whereby a fuel pressure in an accumulator agrees with the target value even if an individual pump unit shows a lowest limit in the variations of the discharge amount. The common correction value is shared among the individual pump units. Even if a starting characteristic is not acquired for each of the individual supply pumps, the internal combustion engine can reliably be started.
摘要翻译：在燃料供给装置的起动模式中，考虑到SCV特性，获得电力的减法值。此外，为了增加内燃机起动时的实际燃料排出量，采用公共校正值作为减法值，由此即使各个泵单元显示最低，蓄能器中的燃料压力与目标值一致限制排放量的变化。共同的校正值在各个泵单元之间共享。即使没有为每个供应泵获取启动特性，也可以可靠地启动内燃机。
