Title (EN) METHOD FOR REDUCING THE NITROUS OXIDE IN MOTOR VEHICLE EXHAUST GASES
(FR) PROCEDE DE DIMINUTION DU PROTOXYDE D'AZOTE DES GAZ D'ECHAPPEMENT DE VEHICULE AUTOMOBILE
Abstract:
(EN) The invention relates to the power train of a motor vehicle, including an internal combustion engine (1; 1'), an exhaust line (3; 3'), a device for post-treating nitrogen oxides (NOx) (4; 4') in the exhaust gases for reducing the amount of nitrogen oxides emitted into the atmosphere, and a device for post-treating nitrous oxide (N2O) (7; 7') in the exhaust gas for reducing the amount of nitrous oxide emitted into the atmosphere, characterised in that the device for post-treating nitrous oxide (N2O) (7; 7') is arranged downstream from the device for post-treating nitrogen oxides (NOx) (4; 4') in the exhaust line (3; 3').
(FR) Groupe motopropulseur de véhicule automobile comprenant un moteur à combustion interne (1; 1 '), une voie d'échappement (3; 3'), un dispositif de post traitement des oxydes d'azote (NOx) (4; 4') des gaz d'échappement destiné à réduire la quantité d'oxydes d'azote rejetée dans l'atmosphère, et un dispositif de post traitement du protoxyde d'azote (N2O) (7; 7') des gaz d'échappement destiné à réduire la quantité de protoxyde d'azote rejetée dans l'atmosphère, caractérisé en ce que le dispositif de post traitement du protoxyde d'azote (N2O) (7; 7') est disposé en aval du dispositif de post traitement des oxydes d'azote (NOx) (4; 4') sur la voie d'échappement (3; 3').
