Method for operating a fuel injection system, in particular for a combustion engine

The method involves injecting fuel stored in a pressurized tank by an injection valve that is formed as a magnet valve. An operating parameter e.g. response time, of the injection valve is evaluated based on a fuel pressure prevailing in the pressurized tank to infer the fuel pressure. The fuel pres...

description The method involves injecting fuel stored in a pressurized tank by an injection valve that is formed as a magnet valve. An operating parameter e.g. response time, of the injection valve is evaluated based on a fuel pressure prevailing in the pressurized tank to infer the fuel pressure. The fuel pressure in the pressurized tank detected by a pressure sensor of a fuel injection system of an internal combustion engine is checked. A comparable deviation of the operating parameter from a predetermined reference data is inferred upon manipulation of the pressure sensor. Independent claims are also included for the following: (1) a computer program that is programmed for the execution of a method for operating a fuel injection system of an internal combustion engine (2) an electronic storage medium in which a computer program is stored, which is programmed for the execution of the method for operating a fuel injection system of an internal combustion engine. Die Erfindung betrifft ein Verfahren zum Betreiben eines Kraftstoffeinspritzsystems (100), insbesondere einer Brennkraftmaschine, bei dem in einem Druckspeicher (110) gespeicherter Kraftstoff von mindestens einem Einspritzventil (120) eingespritzt wird. Erfindungsgemäß wird mindestens eine von dem in dem Druckspeicher (110) herrschenden Kraftstoffdruck abhängige Betriebsgröße (”t) des Einspritzventils (120) ausgewertet, um auf den Kraftstoffdruck zu schließen.
