Abstract: A heating element is provided for an exhaust line, the heating element comprising a substantially tubular housing aligned and/or merging with a pipe of the exhaust line and a heating disc arranged across the housing. The heating disc occupies substantially an entire passage section of the housing and at least two electrodes are electrically connected to the heating disc. The heating disc comprises at least two sectors and a contact member that is arranged between the at least two sectors. The at least two sectors are electrically insulated from each other and electrically connected only by the contact member.

Abstract: A heating device for an exhaust line comprises a substantially flat, perforated, metallic heating element, limited by a shape substantially identical to a section through which the exhaust line passes. The heating element is arranged across the section, The heating device also includes at least one substantially flat, perforated, rigid disk, limited by a shape substantially identical to the section and shaped to support the heating element.

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 vehicle exhaust system includes a component housing defining an internal cavity, a first exhaust gas treatment element positioned within the internal cavity, a second exhaust gas treatment element positioned within the internal cavity and axially spaced from the first exhaust gas treatment element by a gap, and a resonator volume in communication with the internal cavity.
