| 摘要 |
The invention relates to a method for shaping the injection pressure course (27) in injectors, which are used for instance in injection devices of injection systems in motor vehicles. The injection device includes a pump part (1) and an injection nozzle part (2). The pump part (1) and injection nozzle part (2) communicate with one another via a high-pressure line (3). Control valves (8, 10) which are triggered by means of an actuator (9) are contained in the pump part (1). By the triggering by means of the actuator (9), injection parameters during the preinjection phase (28), pressure buildup phase (29) and main injection phase (30) are determined.
