LIGNE D'ECHAPPEMENT EQUIPANT UN MOTEUR THERMIQUE D'UN VEHICULE AUTOMOBILE ET METHODE D'EPURATION DES GAZ D'ECHAPPEMENT

摘要

The invention relates to an exhaust line (2) with which a heat engine (1) of a motor vehicle is to be fitted. The exhaust line (2) comprises a hot area (ZC) and a cold area (ZF). The exhaust line (2) includes a pipe (5) for circulating exhaust gas (3), said pipe containing two oxidation catalysts (DOC1, DOC2) therein, a first oxidation catalyst (DOC1) of which is housed inside the hot area (ZC). The second oxidation catalyst (DOC2) is housed inside the cold area (ZF).
