    Abstract: A heater includes: a conductive ceramic cylinder tube provided with a plurality of cells, each cell being defined by a pair of first cell-walls and a pair of second cell-walls, each first cell-wall extending in a radial direction of the ceramic cylinder tube, and each second cell-wall extending so as to cross the radial direction of the ceramic cylinder tube; an inner electrode electrically coupled to an inner wall of the ceramic cylinder tube; and an outer electrode electrically coupled to an outer wall of the ceramic cylinder tube. Linear portions are radially arranged in the ceramic cylinder tube, each linear portion linearly extending in the radial direction of the ceramic cylinder tube so as to include a plurality of first cell-walls that are arranged on the same axial line that in the radial direction and current flows radially at least via the linear portions between the inner and outer electrodes.

    Abstract: An exhaust gas purification member comprises an annular substrate centered on a central axis, a peripheral electrode alongside and against an outer cylindrical face of the substrate, and a central electrode alongside and against an inner cylindrical face of the substrate. The substrate is made up of an electrically conductive material and includes a plurality of intersecting walls defining longitudinal cells therebetween and that each emerge in an upstream face and in a downstream face of the substrate. These intersecting walls are covered with a catalytic composition and each wall extends from an outer cylindrical wall of the substrate, defining the outer cylindrical face, to the inner cylindrical wall of the substrate, defining the inner cylindrical face.

    Abstract: The exhaust gas purification device for a vehicle comprises an exhaust gas purification member having a plurality of longitudinal circulation channels for the circulation of the exhaust gases, with each circulation channel having a free section. The device further includes a heater, comprised of a plurality of electrically conducting resistive wires engaged longitudinally each in one or several circulation channels, and a power source of the resistive wires. The resistive wires that are engaged in a same circulation channel occupy a total section smaller than 25% of the free section of the circulation channel.

    CPC classification number: F01N3/2013

    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 heater may include: a conductive ceramic cylinder tube in which cell-arrays are concentrically arranged, each cell-array including cells which are arranged in a circumferential direction of the ceramic cylinder tube; an inner electrode electrically coupled to an inner wall portion of the ceramic cylinder tube; and an outer electrode electrically coupled to an outer wall portion of the ceramic cylinder tube. Non-linear portions are radially arranged in the ceramic cylinder tube, each non-linear portion extending in a radial direction of the ceramic cylinder tube while having a plurality of bends or curves between the inner wall portion and outer wall portion of the ceramic cylinder tube. The inner and outer electrodes are provided such that current flows radially at least via said non-linear portions between the inner and outer electrodes.
