Abstract

Durch ein Verfahren und eine Vorrichtung soll die Qualität eines Kraftstoff-Luftgemisches in einer Verbrennungsphase, insbesondere bei einem Ottomotor, ausgewertet werden, um einen schadstoffarmen, kraftstoffsparenden und klopffreien Betrieb zu ermöglichen. Es wird hierfür während der Verbrennungsphase(V) folgend auf den Zündimpuls(Z) ein elektrischer Prüfimpuls(P) an die Zündkerze gelegt. Die Beeinflussung des Prüfimpulses durch das jeweilige Kraftstoff-Luftgemisch des Verbrennungsraumes wird als elektrische Größe erfaßt und ausgewertet.
