Abstract

Die Erfindung betrifft ein Verfahren zur Steuerung einer magerlauffähigen Verbrennungskraftmaschine mit einem in einem Abgaskanal der Verbrennungskraftmaschine angeordneten Katalysatorsystem, bestehend aus mindestens einem Katalysator.The invention relates to a method for controlling a lean-running Internal combustion engine with one in an exhaust duct Internal combustion engine arranged catalyst system consisting of at least one catalyst.

Es ist vorgesehen, dass unzulässige Verbrennungsereignisse registriert werden und eine Steuerung eines Magerbetriebes der Verbrennungskraftmaschine (10) in Abhängigkeit von einer Häufigkeit der unzulässigen Verbrennungsereignisse erfolgt, wobei der Magerbetrieb mit zunehmender Häufigkeit der unzulässigen Verbrennungsereignisse eingeschränkt oder gesperrt wird. Das erfindungsgemäße Verfahren ermöglicht bei der Zulassung eines Magerbetriebs der Verbrennungskraftmaschine (10) die Berücksichtigung einer durch unzulässige Verbrennungsereignisse hervorgerufenen Beeinträchtigung des Katalysatorsystems hinsichtlich seiner Konvertierungsrate, so dass im Ergebnis eine Schadstoffemission reduziert wird.

Figure 00000001
It is provided that impermissible combustion events are registered and lean operation of the internal combustion engine (10) is controlled as a function of a frequency of the impermissible combustion events, the lean operation being restricted or blocked as the frequency of the impermissible combustion events increases. When a lean operation of the internal combustion engine (10) is permitted, the method according to the invention enables consideration of an impairment of the catalytic converter system caused by inadmissible combustion events with regard to its conversion rate, so that pollutant emissions are reduced as a result.
