The present invention relates to an exhaust gas aftertreatment system comprising: a selective catalytic reduction device provided on a selective catalytic reduction line; a methane oxidation catalyst device provided on a methane oxidation catalyst line; and a bypass line through which exhaust gas bypasses the selective catalytic reduction device and the methane oxidation catalyst device, wherein the selective catalytic reduction line, the methane oxidation catalyst line, and the bypass line are formed in parallel, and the selective catalytic reduction device and the methane oxidation catalyst device may be provided adjacent to one another so as to transfer heat to each other.

    La présente invention concerne un système de post-traitement des gaz d'échappement comprenant : un dispositif de réduction catalytique sélective prévu sur une ligne de réduction catalytique sélective ; un dispositif catalyseur d'oxydation de méthane disposé sur une conduite de catalyseur d'oxydation de méthane ; et une conduite de dérivation par l'intermédiaire de laquelle le gaz d'échappement contourne le dispositif de réduction catalytique sélective et le dispositif catalyseur d'oxydation de méthane, la conduite de réduction catalytique sélective, la conduite de catalyseur d'oxydation de méthane et la conduite de dérivation étant formées en parallèle, et le dispositif de réduction catalytique sélective et le dispositif catalyseur d'oxydation de méthane pouvant être disposés adjacents l'un à l'autre de façon à transférer de la chaleur l'un à l'autre.
