摘要： The parameters of command pulses to a flow rate control valve and the solenoid valve of an injector are corrected by utilizing the information obtained from the differential value of a common rail pressure to suppress the deviation from the target injection characteristics of the fuel injection characteristics of the injector. The information on an injection start timing Tis, a total injection quantity Qt, an initial injection quantity Qe and a maximum injection rate Rmax which are the parameters concerning the actual fuel injection by the injector is obtained from the curve of the differential value R of the common rail pressure Pc. The output timings (PTpf and PTif) of command pulses to the flow rate control valve which controls the pumping out quantity of a fuel pump and the solenoid valve of the injector and the widths (PWit and Pwief) of total or initial command pulses to the solenoid valve of the injector are so controlled as to make the parameters agree with the target injection characteristics which are obtained from the operation state of a corresponding engine.

摘要： A high flow rate fuel valve and a fuel supply pump with the valve that are suitable for an accumulated pressure-type fuel injection device (APCRS) that intensifies the pressure of a large amount of fuel using a piston. In a fuel supply pump with a fuel inlet valve and fuel outlet valve, the fuel inlet valve has a valve main body, a valve body received in the valve main body, an inlet chamber provided inside the valve main body, inlet holes, a seat portion where the valve body and part of the valve main body are in contact with each other. The inlet holes are arranged in a non-radial pattern relative to the inlet chamber.

摘要： The invention relates to a fuel injection device (1) comprising one or more pump-nozzle units (6; 36) or pump-line-nozzle units per cylinder which are provided for compressing the fuel. The fuel injection device (1) also comprises means for generating two different injection pressures during injection and at least one valve (24) for controlling the injection with a cross-section control. The pump-nozzle unit (6) or a pump-line-nozzle unit enables the fuel injection to be carried out over a broad r.p.m. range with a high level of precision.

摘要： A pump assembly (10) sends pressurized engine oil to HEUI fuel injectors (12) in a diesel engine. The assembly includes an inlet throttle valve (104) which controls the volume of oil flowing to the pump dependent upon the difference between the pump outlet pressure and a desired outlet pressure determined by an electronic control module for the diesel engine.
