Abstract

Die Erfindung betrifft eine Katalysatoranordnung für die Reinigung der Abgase von mager betriebenen Verbrennungsmotoren. Es wird vorgeschlagen, einen dünnwandigen, porösen Trägerkörper auf der einen Seite mit einem Stickoxid-Speicherkatalysator und auf der anderen Seite mit einem SCR-Katalysator zu beschichten. Wird das Abgas durch die katalytischen Beschichtungen und das Trägermaterial hindurchgeführt, so wird eine wesentliche Verbesserung der Stickoxid-Umsetzung erhalten, verglichen mit einer Hintereinanderschaltung der Katalysatoren auf getrennten Trägerkörpern. Als dünnwandige Trägerkörper haben sich Wandflußfilter bewährt.
