Abstract: A heating element for an exhaust line includes a substantially tubular housing, which merges with an exhaust pipe of the exhaust line, and a heating disk that is arranged across a passage cross-section of the tubular housing. The heating element also includes at least one pad and at least one restoring member, where the at least one pad is fastened to a distal end of the at least one restoring member. The at least one restoring member is able to hold the at least one pad in abutment against the heating disk.

Abstract: A device for the post-treatment of the exhaust gas of an internal combustion engine comprises a conduit defining a passage for the flow of the exhaust gas and, from upstream to downstream of the conduit, an injector arranged to inject a reducing agent into the flow passage, and a purifying member. The injector is heated to heat the reducing agent prior to injection. The device further comprises a heating element arranged between the injector and the purifying member.

Abstract: A heating member for a vehicle exhaust gas purification device comprises an electrically conductive peripheral frame having an inner edge, a central support arranged substantially at a geometric centre of the inner edge, and a perforated heating grid formed of a plurality of elongate heating elements each having first and second ends opposite one another. The first end is linked to the electrically conductive peripheral frame and the second end is linked to the central support. Each elongate heating element occupies a respective angular sector of the perforated heating grid, and is arranged in zigzag manner within that angular sector so as to form a succession of strands connected by nodes and being linked by the nodes to the elongate heating elements occupying neighbouring angular sectors.

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.
