Abstract: A heating member for a vehicle exhaust gas purification device includes an electrically conductive outer peripheral frame that has a geometric center and is symmetrical about an axis. An electrically conductive central support is centered on the geometric center, and a perforated heating grid is centered on the geometric center. The heating grid extends between the electrically conductive central support and the electrically conductive outer peripheral frame. The heating grid is formed of a plurality of strands connected by nodes, with the plurality of strands delimiting openings therebetween.

Abstract: A heating device includes conductive elements, positive and negative electrical terminals, first and second connecting parts each including a first part that is a substantially planar longitudinal part extending in a longitudinal direction, a second connecting part connected to the first part while extending transversely to this first part, the second part being connected to a respective one of the terminals, and at least one third part, connected to the first part while extending transverse to this first part. Each conductive element has one end connected to the second or third part of one of the first and second connecting pieces, and another end connected to the second or third part of the other first and second connecting piece.

Abstract: A heater is suitable to be arranged opposite and away from an upstream or downstream face of an exhaust gas purification member of a vehicle. The heater comprises a fastening ring with an electrically conductive frame having a geometric center, a central support arranged substantially at the geometric center of the frame, and a plurality of elongate heating elements each having first and second ends opposite one another. The first end is connected to the frame and the second end is connected to the central support. The fastening ring further comprises a plurality of electrically conductive radial protrusions distributed around the frame and protruding toward the outside of the frame.

Abstract: The exhaust line comprises an injection segment including at least one cup having a large upstream face directly sprayed with the exhaust gases and dividing a circulation passage into an upstream space and a downstream space. The injection segment comprises at least one circumferential conduit fluidically connecting the upstream space to the downstream space. The cup defines at least one injection channel and at least one guiding area laid out so as to guide as far as said injection channel a portion of the exhaust gases spraying the large upstream face. An injection device includes a reagent injector that is oriented to inject the reagent substantially with a co-current or counter-current of the exhaust gases in the injection channel, with the latter extending from the injector as far as the inlet of the conduit.
