Abstract

Bei einer Brennkraftmaschine gelangt der Kraftstoff mittels eines Injektors in einen Brennraum. Der Injektor wird mit einem Signal angesteuert, welches dem Zustand eines Stellglieds (16) des Injektors beeinflusst. Es wird vorgeschlagen, dass außerhalb einer geplanten Einspritzung (36) zumindest zeitweise überwacht wird (46), ob das Stellglied (16) zusätzlich angesteuert wird, und dass abhängig vom Ergebnis der Überwachung (46) eine Maßnahme durchgeführt wird (48).

In an internal combustion engine, the fuel passes by means of an injector into a combustion chamber. The injector is driven by a signal which influences the state of an actuator (16) of the injector. It is proposed that outside of a planned injection (36) at least temporarily monitored (46), whether the actuator (16) is additionally controlled, and that depending on the result of the monitoring (46) a measure is performed (48).
