Abstract: A purification device comprises a housing comprising a generally cylindrical wall extending along a longitudinal axis. At least one purification member is arranged in the housing and is intended to be arranged in an exhaust gas flow. The purification device comprises at least one heating element arranged in contact with the purification member, the heating element extending in a plane perpendicular to the longitudinal axis.

Abstract: An exhaust gas purification device comprises a conduit defining a flow passage for exhaust gases. The exhaust gas purification device comprises at least one purification unit, where each purification unit is arranged in the conduit and comprises an exhaust gas purification component arranged in the flow passage and at least one mixer arranged upstream of the exhaust gas purification component. The exhaust gas purification device comprises at least one injector arranged to inject a reducing agent into the flow passage. The exhaust gas purification device comprises a heating element for heating the exhaust gas and the reducing agent, with the heating element being arranged upstream of the mixer of the purification unit or one of the purification units.

Abstract: A device includes at least one ammonia storage cartridge comprising an outlet orifice for ammonia intended to be connected to an ammonia transport circuit towards an exhaust line. The device includes an obturator to obturate the outlet orifice, and which is capable of changing between an obturation configuration of the outlet orifice and a configuration for clearance the outlet orifice. The device includes a detector to detect at least one predefined situation, and a controller to control the obturator, and which is capable of controlling the transition of the obturators towards their obturation configuration when the detector detects the predefined situation.
