    摘要： The invention relates to a fuel injection valve (13) driving method by means of a fuel supply pressure detector (21) involves various types of delay including a response lag of the fuel supply pressure detector (21), a lag produced by a noise filter of a signal processing circuit, and a lag produced by a software filter provided in an arithmetic unit. These delay factors produce a lag in increasing the value of current supplied to the fuel injection valve (13) despite the fact that an actual fuel supply pressure is already high. Then, no attractive force for overcoming the fuel supply pressure is generated in the fuel injection valve (13), so that a condition arises in which fuel is not injected due to the fuel injection valve (13) not being opened.
    An overexciting current (33a) and a holding current (34a) supplied to the fuel injection vale (13) in accordance with a target fuel supply pressure as obtained from an operating condition are controlled, thereby controlling the opening and holding of the open position of the fuel injection valve (13).

    摘要： In feedback control of a discharge amount of a high pressure fuel pump in which an actual fuel pressure is caused to become a target fuel pressure, when a deviation between the target fuel pressure and the actual fuel pressure has transiently changed, updating of an integral term of the feedback control is stopped. As a result, needless updating of the integral term when the deviation of the target fuel pressure and the actual fuel pressure has transiently increased is inhibited, and fuel pressure overshoot is reliably suppressed.

    摘要： The injection system (1) includes a pump (7) for supplying high-pressure fuel to a storage volume, defined for example by a common rail (6), for supplying a number of injectors (5). The pump (7) has at least one reciprocating pumping member (18) with a sinusoidal compression stroke (24). The injection system (1) includes at least one bypass solenoid valve (14) controlled by a control unit (16) having a chopper unit (28) for producing multiple deliveries (29,31) at each compression stroke (24), so that the pressure in the common rail (6) is substantially level. Each pumping member (18) may be associated with a corresponding bypass solenoid valve (14), which is integrated with the pump and adjacent to or facing the pump compression chamber.

    摘要： A fuel supply device includes a fuel pump (22), a plurality of valves (111, 121, 131, 141), and a controller (31). The fuel pump (22) includes a plurality of pressure chambers (402a) each having a volume that is expanded and contracted by the engine. The plurality of valves (111, 121, 131, 141) open and close the pressure chambers (402a). An expansion time and a contraction time of the pressure chambers (402a) are each different. The fuel pump (22) is operable to sealingly store fuel in the pressure chambers (402a) by closing the valves (111, 121, 131, 141). The controller (31) sets closing times for the valves (111, 121, 131, 141) in accordance with a required quantity of fuel to be force fed. The controller (31) switches between a normal control in which all of the pressure chambers (402a) sequentially force feed fuel and a thinned-out control in which the force fed fuel is thinned out by stopping closing at least one of the valves (111, 121, 131, 141).
