Abstract

Die Erfindung betrifft ein Verfahren zur Steuerung eines Betriebsmodus einer magerlauffähigen Verbrennungskraftmaschine (10) mit einem Abgastrakt (14), der mindestens einen NOx-Speicherkatalysator (20) und einem diesem nachgeschalteten Gassensor (24) umfasst.
Hierzu ist vorgesehen, dass
  • ein Magerbetriebsmodus der Verbrennungskraftmaschine (10) mit λ > 1 in Abhängigkeit von vorgebbaren Schwellenwerten für eine Temperatur (TSK) des NOx-Speicherkatalysators (20) und für mindestens einen weiteren Betriebsparameter der Verbrennungskraftmaschine (10) und/oder des Abgastraktes (14) zugelassen wird und
  • mindestens ein Schwellenwert in Abhängigkeit einer aktuellen NOx-Speicherund/oder NOx-Konvertierungsfähigkeit des NOx-Speicherkatalysators (20) variiert wird.
