Abstract

Verfahren zur Regelung des Kraftstoff/Luft-Verhältnisses eines Verbrennungsprozesses, der abwechselnd mit Luftüberschuß und Luftmangel betrieben wird, und mit wenigstens einem Katalysatorvolumen im Abgas des Verbrennungsprozesses, das bei Sauerstoffüberschuß im Abgas Sauerstoff speichert und diesen bei Sauerstoffmangel abgibt bei welchem Verfahren die bei Luftüberschuß erfolgenden Sauerstoffeinträge in das Katalysatorvolumen und die bei Luftmangel erfolgenden Sauerstoffausträge aus dem Katalysatorvolumen bestimmt werden und bei dem das Kraftstoff/Luftverhältnis in einem ersten Regelkreis so geregelt wird, dass die Summe der in einem vorbestimmten Intervall bestimmten Sauerstoffeinträge und Sauerstoffausträge einen vorbestimmten Wert annimmt, dadurch gekennzeichnet, dass der Verbrennungsprozeß jeweils mindestens solange mit Sauerstoffüberschuß oder Sauerstoffmangel betrieben wird, bis dieser an einer sauerstoffempfindlichen Nernstsonde hinter dem Katalysatorvolumen auftritt.
