Title (EN) MODEL-BASED SYSTEM AND METHOD FOR MITIGATING DIESEL EMISSION FLUID DEPOSITS
(FR) SYSTÈME BASÉ SUR MODÈLE ET PROCÉDÉ POUR RÉDUIRE LES DÉPÔTS DE FLUIDES DES ÉMISSIONS DE DIESEL
Abstract: front page image
(EN) A system and method for mitigating deposit of diesel emission fluid (DEF) decomposition products on interior surfaces of an internal combustion engine exhaust system (14). A processor in a controller (34) contains a model-based control algorithm (50A; 50B) for controlling DEF injection by a DEF injector (24) to mitigate deposit formation.
(FR) L'invention porte sur un système et un procédé pour atténuer le dépôt de produits de décomposition des fluides des émissions de diesel (DEF) sur les surfaces internes du système d'échappement d'un moteur à combustion interne (14). Un processeur inclus dans une unité de commande (34) contient un algorithme de commande basé sur modèle (50A ; 50B) pour commander l'injection de DEF par un injecteur de DEF (24) pour réduire la formation de dépôts.
