Title (EN) CATALYST AND METHOD FOR REDUCING EXHAUST GAS EMISSIONS
(FR) CATALYSEUR ET PROCEDE DE REDUCTION DES EMISSIONS DE GAZ D'ECHAPPEMENT
Abstract: front page image
(EN)An apparatus useful to treat exhaust gas stream, including diesel engine exhaust. The exhaust stream passes from an exhaust outlet to a catalyzed filter in communication with the exhaust outlet. The catalyzed filter comprises a first catalyst which comprises a first platinum group metal; a first cerium component; and preferably a zirconium component. There can be a second catalyst in communication with the first catalyst, the second catalyst comprises a second cerium component.
(FR)L'invention concerne un appareil utile pour traiter un flux de gaz d'échappement, notamment l'échappement de moteurs Diesel. Un flux d'échappement passe d'une sortie d'échappement à un filtre catalysé en communication avec la sortie d'échappement. Le filtre catalysé comprend un premier catalyseur comportant un premier métal du groupe du platine, un premier constituant cérium, et de préférence un constituant zirconium. On peut prévoir un second catalyseur en communication avec le premier catalyseur, le second catalyseur comprenant un second constituantérium.
