Abstract

Die Erfindung betrifft ein Verfahren zur Regelung einer NOX-Regeneration eines im Abgasstrang einer magerlauffähigen Verbrennungskraftmaschine angeordneten NOX- Speicherkatalysators.
Es ist vorgesehen, dass ein Schädigungszustand des NOX-Speicherkatalysators (14) erfasst und in Abhängigkeit von dem Schädigungszustand ein Reduktionsmittel-Massenstrom während der NOX-Regeneration und/oder eine Regenerationsabbruch-Spannungsschwelle (Si) an einer stromab des NOX-Speicherkatalysators (14) angeordneten, ermittelnden Lambda-Gassonde (20) vorgegeben werden.
