Abstract

Die Erfindung betrifft ein Verfahren zum Betreiben einer Verbrennungskraftmaschine. Gemäss dem Verfahren wird ein von der Verbrennungskraftmaschine erzeugtes Abgas über einen im Abgaskanal angeordneten 3-Wege-Katalysator geführt. Eine Lambdasonde erfasst eine für ein Abgaslambda charakteristische Grösse vor dem 3-Wege-Katalysator und leitet diese an ein Motorsteuergerät mit integriertem PI- oder PID-Regler weiter. Mit dem PI- oder PID-Regler des Motorsteuergeräts wird durch Vorgabe eines Sollwertes ein im Wesentlichen stöchiometrisches Abgaslambda eingestellt und das Abgaslambda mit vorgegebener periodischer Sollwertvariation alternierend in Richtung eines Magerlambdawertes und eines Fettlambdawertes ausgelenkt (Lambdamodulation). Zu Beginn einer jeden Sollwertvariation wird ein vorgesteuerter P-Anteil mit anschliessendem I-Anteil bis zu einem Zeitpunkt t2 vorgegeben, wobei der Zeitpunkt t2 mittels hinterlegter, ein Streckenzeitverhalten charakterisierender Parameter so festgelegt wird, dass zu diesem Zeitpunkt t2 das Sondensignal oder eine davon abgeleitete Grösse die Sollwertvorgabe erreicht haben müsste. Vom Zeitpunkt t2 an wird für eine vorgebbare Zeitspanne bis zum Ende der jeweiligen Sollwertvariation auf eine Regelung umgeschaltet, welche auf einer Differenz zwischen einem Istwert und dem Sollwert der Lambdasonde oder einer davon abgeleiteten Grösse beruht.
