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.
