Title
(EN) AN AFTERTREATMENT SYSTEM
(FR) SYSTÈME DE POST-TRAITEMENT
Abstract
(EN)
An aftertreatment system (100) connected downstream an internal combustion engine arrangement (102) for receiving combustion gas exhausted from the internal combustion engine arrangement (102) during operation thereof, the aftertreatment system (100) comprising a primary aftertreatment system (104) comprising a first catalytic reduction arrangement (106); a secondary reduction system (108) comprising a second catalytic reduction arrangement (110).
(FR)
L'invention concerne un système de post-traitement (100) relié en aval d'un agencement de moteur à combustion interne (102) pour recevoir le gaz de combustion évacué de l'agencement de moteur à combustion interne (102) pendant son fonctionnement, le système de post-traitement (100) comprenant un système de post-traitement primaire (104) comprenant un premier agencement de réduction catalytique (106) ; un système de réduction secondaire (108) comprenant un second agencement de réduction catalytique (110).
