Abstract
Die Erfindung betrifft ein Verfahren zum Betreiben eines Einspritzventils (10), insbesondere eines Kraftstoffeinspritzventils einer Brennkraftmaschine, bei dem ein als piezoelektrisches Element ausgebildeter Aktor (12) des Einspritzventils (10) mit einer Ansteuerspannung (U) beaufschlagbar ist, um eine Einspritzung von, dem Einspritzventil (10) über ein Zufuhrsystem zugeführtes Fluid, insbesondere Kraftstoff, zu bewirken.The invention relates to a method for operating an injection valve (10), in particular a fuel injection valve of an internal combustion engine, in which a piezoelectric element formed as an actuator (12) of the injection valve (10) with a drive voltage (U) can be acted upon to an injection of, the Injection valve (10) via a supply system supplied fluid, in particular fuel to cause.
Erfindungsgemäß wird der Aktor (12) in einer Testansteuerung mit einer vorgebbaren Testspannung beaufschlagt, und ein in dem Zufuhrsystem herrschender Fluiddruck wird zumindest während der Testansteuerung erfasst, um aus der Testspannung und dem erfassten Fluiddruck Informationen über einen Betriebszustand des Einspritzventils (10) und/oder des Aktors (12) abzuleiten. According to the invention, the actuator (12) is subjected to a predeterminable test voltage in a test drive, and a fluid pressure prevailing in the supply system is detected at least during the test drive in order to obtain information about an operating state of the injection valve (10) from the test voltage and the detected fluid pressure der der Aktors (12) derive.
