Title (EN) DIESEL OXIDATION CATALYST AND USE THEREOF IN DIESEL AND ADVANCED COMBUSTION DIESEL ENGINE SYSTEMS
(FR) CATALYSEUR D'OXYDATION DIESEL ET SON UTILISATION DANS DES SYSTÈMES DE MOTEUR DIESEL ET À COMBUSTION AVANCÉE DIESEL
Abstract:
(EN) An oxidation catalyst composite, methods and systems for the treatment of exhaust gas emissions from an advanced combustion engine, such as the oxidation of unburned hydrocarbons (HC), and carbon monoxide (CO) and the reduction of nitrogen oxides (NOx) from a diesel engine and an advanced combustion diesel engine are disclosed. More particularly, washcoat compositions are disclosed comprising at least two washcoat layers, a first washcoat comprising a palladium component and a first support containing cerium and a second washcoat containing platinum and one or more molecular sieves.
(FR) La présente invention a pour objet un composite de catalyseur d'oxydation, des procédés et des systèmes pour le traitement des émissions de gaz d'échappement émanant d'un moteur à combustion avancée, comme l'oxydation des hydrocarbures (HC) non brûlés, et du monoxyde de carbone (CO) et la réduction des oxydes d'azote (NOx) émanant d'un moteur diesel et d'un moteur à combustion avancée diesel. Plus particulièrement, la présente invention a pour objet des compositions d'imprégnation comprenant au moins deux couches d'imprégnation, une première couche d'imprégnation comprenant un composant du palladium et un premier support contenant du cérium et une seconde couche d'imprégnation contenant du platine et un ou plusieurs tamis moléculaires.
