Abstract

Die Erfindung betrifft ein Verfahren zum Betreiben einer Brennkraftmaschine, insbesondere Dieselmotor oder Ottomotor, insbesondere eines Kraftfahrzeugs, mit einer Abgasnachbehandlungsanlage mit wenigstens einem Vorkatalysator und wenigstens einem dem Vorkatalysator nachgeordneten Hauptkatalysator, wobei mittels einer Lambdaregelung aus einer Differenz zwischen einem Lambda-Sollwert und einem nach dem Vorkatalysator gemessenen Lambda-Istwert ein Regeleingriff für die Gemischsteuerung errechnet wird. Hierbei wird am Ende eines über eine gewisse Zeitspanne stationären Betriebszustandes der Brennkraftmaschine ein I-Anteil der Lambdaregelung als Adaptionswert einer Gemischvorsteuerung für diesen Betriebszustand abgespeichert, sofort für diesen Betriebszustand als Adaptionswert für die Gemischvorsteuerung verwendet und der I-Anteil der Lambdaregelung auf null gesetzt.
