Title (EN) PASSIVE AMMONIA-SELECTIVE CATALYTIC REDUCTION FOR NOX CONTROL IN INETERNAL COMBUSTION ENGINES
(FR) RÉDUCTION CATALYTIQUE SÉLECTIVE D’AMMONIAC PASSIVE POUR LE CONTRÔLE DE NOX DANS DES MOTEURS À COMBUSTION INTERNE
Abstract: front page image
(EN)Engine exhaust gas feedstream NOx emissions aftertreatment includes a three-way catalytic device connected upstream of an ammonia-selective catalytic reduction device including a base metal. Engine operation can be modulated to generate an engine-out exhaust gas feedstream that converts to ammonia on the three-way catalytic device. The ammonia is stored on the ammonia-selective catalytic reduction device, and used to reduce NOx emissions in the exhaust gas feedstream.
(FR)L’après-traitement des émissions de NOx d’un courant d’alimentation de gaz d’échappement comprend un dispositif catalytique trivalent connecté en amont d’un dispositif de réduction catalytique sélective d’ammoniac comprenant un métal de base. Le fonctionnement du moteur peut être modulé afin de générer un courant d’alimentation de gaz d’échappement hors du moteur, converti en ammoniac par le dispositif catalytique trivalent. L’ammoniac est stocké sur un dispositif de réduction catalytique sélective d’ammoniac et utilisé pour réduire les émissions de NOx dans le courant d’alimentation des gaz d’échappement.
