    Abstract: A device for treating exhaust gases includes at least one purification member with a substrate for purifying the exhaust gases, a heat exchanger axially located beyond an axial end of the substrate, a body, a valve comprising a flap arranged in an internal volume of the body. An exchanger inlet and exchanger outlet open into the internal volume. At least 45% of a volume of the body is in a virtual space located in an axial extension of one or more purification substrate(s). The body comprises at least one first orifice in fluid communication with a purification member outlet, and a second orifice defining an outlet for the exhaust gases.

    Abstract: A purification device includes an outer housing canning, extending along a longitudinal axis, and in which exhaust gas is configured to circulate A purification unit is housed in the outer housing canning and incorporates at least one inductive element. An inner induction canning is housed in the outer housing canning and surrounds the purification unit, and comprises an induction device configured to induce an electric current in the at least one inductive element. A holding and insulation assembly is housed in the outer housing canning and surrounds the purification unit. The holding and insulation assembly includes at least one of: an inner holding web positioned radially between the inner induction canning and the purification unit, and/or end rings surrounding the purification unit and positioned on either side of the inner induction canning in a longitudinal direction parallel to the longitudinal axis.

    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.

    Abstract: An injection device comprises a volume, an injection device to inject a jet of liquid reagent into the volume, at least one first impactor positioned in the volume, and a first heating device to heat the first impactor. The first heating device comprises a first heating member having a device having a thermally conductive zone in contact with the first impactor or defining the first impactor. A resistive heating element is housed in the device and arranged to heat the thermally conductive zone.
