Title (EN) CATALYTIC CONVERTER FOR CLEANING THE EXHAUST GASES OF DIESEL ENGINES
(FR) CATALYSEUR SERVANT À LA PURIFICATION DES GAZ D’ÉCHAPPEMENT DE MOTEURS DIESEL
(DE) KATALYSATOR ZUR REINIGUNG DER ABGASE VON DIESELMOTOREN
Abstract:
(EN) The present invention relates to a catalytic converter that comprises a support body that has a length L extending between a first end face a and a second end face b and comprises catalytically active material zones A, B and C, which are arranged on the support body and have different compositions, wherein: material zone A contains platinum or platinum and palladium in a weight proportion Pt : Pd of > 1 and proceeding from end face a or proceeding from end face b extends over 70 to 100% of the length L; and material zone B contains palladium or platinum and palladium and proceeding from end face b extends over a portion of the length L; and material zone C contains SCR-active material and proceeding from end face a extends over a portion of length L, wherein material zone C is arranged above material zone A.
(FR) La présente invention concerne un catalyseur qui comporte un corps de support présentant une longueur L qui s'étend entre une première face frontale a et une deuxième face frontale b et comportant des zones de matériau A, B et C disposées sur le corps de support, à effet catalytique et composées différemment. La zone de matériau A contient du platine ou du platine et du palladium dans un rapport pondéral Pt :Pd > 1 et s'étend à partir de la face frontale a ou à partir de la face frontale b sur 70 à 100 % de la longueur L. La zone de matériau B contient du palladium ou du platine et du palladium et s'étend à partir de la face frontale b sur une partie de la longueur L. La zone de matériau C contient un matériau à effet de réduction catalytique sélective (SCR) et s'étend à partir de la face frontale a sur une partie de la longueur L. La zone de matériau C et la zone de matériau A sont superposées.
(DE) Die vorliegende Erfindung betrifft einen Katalysator, der einen Tragkörper mit einer Länge L, die sich zwischen einer ersten Stirnfläche a und einer zweiten Stirnfläche b erstreckt und auf dem Tragkörper angeordnete, unterschiedlich zusammengesetzte katalytisch aktive Materialzonen A, B und C umfasst, wobei - Materialzone A Platin oder Platin und Palladium in einem Gewichtsverhältnis Pt : Pd von > 1 enthält und sich ausgehend von Stirnfläche a oder ausgehend von Stirnfläche b auf 70 bis 100% der Länge L erstreckt, und - Materialzone B Palladium oder Platin und Palladium enthält und sich ausgehend von Stirnfläche b auf einem Teil der Länge L erstreckt, und - Materialzone C SCR-aktives Material enthält und sich ausgehend von Stirnfläche a auf einem Teil der Teil der Länge L erstreckt, wobei Materialzone C über Materialzone A angeordnet sind.
