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.

摘要： The invention relates to an injection valve (10) for the fuel injection in a internal combustion engine, in particular in a diesel engine. The injection valve (10) has a holder body (20) in which a first passage (30) is formed. At the holder body (20) a nozzle body (40) of an injection nozzle (16) is secured in which a second passage (54) is formed which is connected to the first passage (30) and which together with the latter forms a fuel infeed line for the injection nozzle (16). Moreover, a closure mechanism (60) is provided for the closing off of the injection nozzle (16). A sleeve (74) serves for the sealing off of the connection point between the first and the second passage (30, 54).
