Method for operating injection system, particularly pump-nozzle-unit, in internal combustion engine, involves establishing injection pressure by pump, which is used to inject fuel into combustion chamber through nozzle

The method involves establishing an injection pressure by a pump. The injection pressure is used to inject the fuel into a combustion chamber of the internal combustion engine through a nozzle (15) of the injection system. A reference-injection pressure is specified for the injection pressure. A cor...

Beschreibung
Zusammenfassung:	The method involves establishing an injection pressure by a pump. The injection pressure is used to inject the fuel into a combustion chamber of the internal combustion engine through a nozzle (15) of the injection system. A reference-injection pressure is specified for the injection pressure. A correcting variable is determined for the injection system depending on the parameters that include reference-injection pressure, starting output, speed, fuel temperature, injection volume and previous occurrence of injection. Independent claims are also included for the following: (1) a computer program product that has program code for the execution of the steps of the method (2) a device that has a unit for the operation of an injection system. Verfahren zum Betrieb eines Einspritzsystems (1), insbesondere einer Pumpe-Düse-Einheit (1), einer Brennkraftmaschine, bei dem durch eine Pumpe ein Einspritzdruck (p) aufgebaut wird, mit dem Kraftstoff durch eine Düse (15) des Einspritzsystems in einen Brennraum der Brennkraftmaschine eingespritzt wird. Für den Einspritzdruck (p) wird ein Soll-Einspritzdruck vorgegeben.
