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： In the fuel injection method and device for engines, information obtained from the differential value of the common rail pressure is used to correct the parameters of the command pulses to the flow control valve and the solenoid valve of each injector and thereby limit deviations of the fuel injection characteristic of the injector from the target injection characteristic. From the curves of the differential values R of the common rail pressure Pc, the actual fuel injection parameters for the injectors-injection start timing Tis, gross injection amount Qt, initial injection amount Qe and maximum injection rate Rmax-are obtained. The command pulse output timing (PTpf, PTif) for the flow control valve, which controls the amount of fuel delivered from the fuel pump, and for the solenoid valve of each injector and the gross or initial command pulse width (PWit, PWief) for the solenoid valves of each injector are controlled so that the above parameters agree with the target injection characteristic determined from the corresponding operating states of the engine.
