Zusammenfassung:	The method for determining fuel quality in diesel engines comprises altering the setting of the glow plugs when the engine is running in prescribed conditions, especially when idling. Any alteration in the running of the engine is then used as a measure of the fuel quality. Independent claims are included for: (A) a computer program for use in the method and (B) a control unit for use in it. Es wird ein Verfahren zur Erkennung der Kraftstoffqualität bei laufender Brennkraftmaschine vorgeschlagen, bei dem durch Einschalten der Glüheinrichtung der Brennkraftmaschine die Zündbedingungen verbessert werden und aus den daraus resultierenden Änderungen von relevanten Betriebsparametern der Brennkraftmaschine, wie beispielsweise der Einspritzmenge, auf die Kraftstoffqualität geschlossen wird. Durch entsprechende Ansteuerung der Stellglieder der Brennkraftmaschine können unter Berücksichtigung der Kraftstoffqualität die Unterschiede im Zündverhalten weitestgehend kompensiert werden.
