Title (EN) EMISSIONS TREATMENT SYSTEMS AND METHODS WITH CATALYZED SCR FILTER AND DOWNSTREAM SCR CATALYST
(FR) SYSTÈMES ET PROCÉDÉS DE TRAITEMENT D'ÉMISSIONS EMPLOYANT UN FILTRE RCS CATALYSÉ ET UN CATALYSEUR RCS AVAL
Abstract:
(EN) Emissions treatment systems and methods for treating an engine exhaust gas stream containing NOx and particulate matter are disclosed including a particulate filter comprising a first SCR catalyst for NOx conversion a second SCR catalyst for NOx conversion on a substrate disposed downstream of the particulate filter. The system NOx conversion and the system back pressure increase lie within a targeted operational window.
(FR) L'invention concerne des systèmes et des procédés de traitement d'émissions pour traiter un courant de gaz d'échappement de moteur contenant des NOx et des matières particulaires, qui comprennent un filtre à particules comprenant un premier catalyseur RCS pour la conversion des NOx et un deuxième catalyseur RCS pour la conversion des NOx sur un substrat placé en aval du filtre à particules. Le système de conversion des NOx et la contre-pression du système améliorent le positionnement dans une fenêtre opérationnelle ciblée.
