Abstract

Die Erfindung betrifft ein Verfahren zum Betreiben einer direkteinspritzenden Brennkraftmaschine, welche ein Katalysatorsystem mit einem NOx-Speicherkatalysator aufweist, in verschiedenen Betriebsarten, wobei sich in wenigstens einer ersten Betriebsart NOx in den NOx-Speicherkatalysator einlagert und in wenigstens einer zweiten Betriebsart NOx aus dem NOx-Speicherkatalysator abgegeben wird. Hierbei ist in einem Last-Drehzahl-Kennfeld der Brennkraftmaschine zwischen einem ersten Kennfeldbereich, in dem die erste Betriebsart zugelassen ist, und einem zweiten Kennfeldbereich, in dem die zweite Betriebsart zugelassen ist, ein dritter Kennfeldbereich vorgesehen, in dem die Brennkraftmaschine lediglich für eine vorbestimmte Zeitdauer in der ersten Betriebsart betrieben wird und nach Ablauf der vorbestimmten Zeitdauer in die zweite Betriebsart des zweiten Kennfeldbereichs umgeschaltet wird.
