Title (EN) A METHOD FOR CONTROLLING THE TEMPERATURE OF A NOX CONTROLLING COMPONENT AND AN EXHAUST AFTER TREATMENT SYSTEM
(FR) PROCÉDÉ DE RÉGULATION DE LA TEMPÉRATURE D'UN COMPOSANT DE RÉDUCTION DE NOX ET D'UN SYSTÈME DE POST-TRAITEMENT DES GAZ D'ÉCHAPPEMENT
Abstract:
(EN) The invention relates to a method for controlling the temperature of an NOx controlling component (10) in an exhaust after treatment system (1, 1') of an internal combustion engine (100). The NOx controlling component (10) has inner surface portions (12) defining an interior component space (20) through which exhaust gases (3) are arranged to flow in order to be NOx controlled, and has outer surface portions (14) facing away from the interior component space (20). The method comprises the step of: controlling the temperature of at least a portion of the NOx controlling component (10) by a heat transfer medium (30, 30') arranged outside of the outer surface portions (14).
(FR) L'invention concerne un procédé de régulation de la température d'un composant de réduction de NOx (10) dans un système de post-traitement des gaz d'échappement (1, 1') d'un moteur à combustion interne (100). Le composant de réduction de NOx (10) a des parties de surface intérieure (12) définissant un espace de composant intérieur (20) à travers lequel des gaz d'échappement (3) s'écoulent afin de subir une réduction des NOx, et a des parties de surface extérieure (14) orientées à l'opposé de l'espace de composant intérieur (20). Le procédé comprend l'étape consistant à : réguler la température d'au moins une partie du composant de réduction de NOx (10) par un milieu de transfert de chaleur (30, 30') situé à l'extérieur des parties de surface extérieure (14).
