A catalyst substrate may include a ceramic base body including first and second ends, the second end being opposite to the first end, and the ceramic base body being provided with a plurality of cells each extending between the first and second ends; and a plurality of metal particles or metal fragments introduced into one or more internal spaces of one or more selected cells in the plurality of cells. Each of the plurality of metal particles or metal fragments has a size equal to or less than an opening width of the cell. The plurality of metal particles or metal fragments is configured to generate heat in accordance with varying magnetic field.

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.

Double canning exhaust gas purification device

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.

Exhaust gas treatment device, exhaust line and method of manufacture

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.

Exhaust line, exhaust gas purification device, and purification device manufacturing process

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.

Injection device for a reducing agent and corresponding exhaust line

The assembly for purification of exhaust gases comprises A space has an exhaust gas inlet communicating with the upstream conduit and an exhaust gas outlet communicating with the downstream conduit. A middle line divides the inlet into first and second areas providing a same passage section to the exhaust gases. The assembly comprises a baffle covering at least 75% of the first area and covering less than 25% of the second area. The baffle and the space are laid out so that a portion of the exhaust gases penetrate through the first area of the inlet flows into the space along flow lines forming a cusp around the baffle.

Assembly for purifying exhaust gases

A motor vehicle exhaust line includes a hot pipe, and a cold pipe for exhaust gases. A mechanical decoupling element connects a downstream end of the hot pipe to an upstream end of the cold pipe. The exhaust line also includes a nitrogen oxide treatment device and an injector intended to reinject a reagent into, or to produce a reagent in the exhaust line upstream of the nitrogen oxide treatment device. The exhaust line includes a mixer intended to mix the exhaust gases and the reagent injected or produced by the injector. The mixer is positioned upstream of the nitrogen oxide treatment device. The nitrogen oxide treatment device is disposed in the cold pipe downstream of the mechanical decoupling element. The injector and the mixer form an assembly connected directly to the mechanical decoupling element.

Motor vehicle exhaust line

An exhaust line has upstream and downstream blocks for processing exhaust gases. An injection section is arranged between an upstream face defined by the upstream block and a downstream face defined by the downstream block and includes a circulation channel for the exhaust gas flow extending from the upstream face to the downstream face. The channel includes a central line having a determined length between the upstream and downstream faces. The injection section includes a reagent injector capable of injecting a reagent into the injection section. The injection section has a first cup inside the circulation channel in the flow path such that the average path of exhaust gas jets is higher by at least 20% in relation to the predetermined length. A second cup is arranged inside the circulation channel between the upstream face and the first cup. The reagent is done between the first cup and the second cup.

Exhaust line with injection system

A device for removing pollutants from exhaust gases of a combustion engine, includes a longitudinal outer casing () defining a passage through which the exhaust gases flow, and first and second pollution-removal members () mounted in series in the passage. The device includes a holding sleeve () holding the first pollution-removal member () in place and interposed between the first pollution-removal member () and the outer casing () and running longitudinally at least over most of the length of the first pollution-removal member (), the holding sleeve () being guided in the external casing () and forming, between the first and second pollution-removal members () a longitudinal thrust surface () against which the first pollution-removal member () bears.
