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