Abstract: The device for treating exhaust gases comprises: at least one purification member (3, 85), with a substrate (11, 87) for purifying the exhaust gases; a heat exchanger (5) axially located beyond an axial end of the substrate (11, 87); a body (29); a valve (7) comprising a flap (31) arranged in the internal volume of the body (29). The exchanger inlet (25) and the exchanger outlet (27) open into the internal volume. At least 45% of a volume of the body (29) is in a virtual space (E) located in the axial extension of the one of more purification substrate(s) (11, 87). The body (29) comprises at least one first orifice (39) in fluid communication with the purification member outlet (20), and a second orifice (41) defining an outlet for the exhaust gases.

Abstract: An exhaust gas purification device for a vehicle includes a tubular enclosure having a central axis, a purification member for exhaust gases housed in the tubular enclosure, an electric heating member housed in the tubular enclosure, and a power source electrically powering the electric heating member. The electric heating member comprises a heating plate made from an electrically conductive material extending in a plane substantially perpendicular to the central axis. The heating plate has a solid center and at least two branches, each branch extending in a spiral from the solid center to a free end located near the tubular enclosure. The heating plate is permeable to the exhaust gases and comprises a network of passages for the exhaust gas generating a turbulent flow of the exhaust gases through the heating plate.
