Abstract

L’invention concerne une ligne d’échappement des gaz pour un moteur thermique, comportant un système de dépollution (2) présentant de manière successive au moins un catalyseur (22) et un filtre à particules (23), caractérisé en ce qu’elle comporte un système de préchauffage du système de dépollution (2), configuré pour être actionné avant le démarrage du moteur thermique, ledit système comprenant une ligne de dérivation (3) comprenant un piquage de prélèvement (31) des gaz ménagé en aval du système de dépollution (2) et un piquage d’injection (32) ménagé en amont du système de dépollution (2), une pompe à air (4), un clapet (5) ménagé dans la ligne de dérivation (3) ainsi que des moyens de chauffage des gaz circulant dans la ligne de dérivation (3). Figure 1The invention relates to a gas exhaust line for a combustion engine, comprising a depollution system (2) successively having at least one catalyst (22) and one particulate filter (23), characterized in that it comprises a system for preheating the pollution control system (2), configured to be actuated before starting the heat engine, said system comprising a bypass line (3) comprising a gas sampling tapping (31) arranged downstream of the depollution (2) and an injection tapping (32) provided upstream of the depollution system (2), an air pump (4), a valve (5) provided in the bypass line (3) as well as means for heating the gases flowing in the bypass line (3).
