Method for determining wear state of e.g. spark plug for internal combustion engine of e.g. passenger car, involves detecting wear value of ignition element corresponding to state value determined as function of amount of alcohol in fuel

The method involves determining state value (14) of ignition element as a function of amount of alcohol in fuel injected into combustion chamber of internal combustion engine. The wear value (10) of the ignition element is detected using a sensing element corresponding to the state value. The wear v...

Beschreibung
Zusammenfassung:	The method involves determining state value (14) of ignition element as a function of amount of alcohol in fuel injected into combustion chamber of internal combustion engine. The wear value (10) of the ignition element is detected using a sensing element corresponding to the state value. The wear value of the ignition element is displayed in cockpit of motor vehicle. An instruction signal is provided to the occupants of the vehicle, if the wear value exceeds or decreases below a predetermined threshold value. Die Erfindung betrifft ein Verfahren zum Ermitteln wenigstens eines, einen Verschleißzustand charakterisierenden und einem Zündungselement zum Zünden eines Kraftstoff enthaltenden Gemisches in einem Brennraum einer Verbrennungskraftmaschine eines Kraftwagens zugeordneten Verschleißwerts (10), wobei der Verschleißwert (10) in Abhängigkeit von wenigstens einem mittels eines Erfassungselements erfassten und eine Menge von Alkohol im Kraftstoff charakterisierenden Zustandswert (14) ermittelt wird.
