Abstract: A heating device for an exhaust system has an electrically conductive foamed part and at least one stabilization part for the foamed part. The foamed part includes two end faces, an outer circumference and at least one recess starting from the outer circumference and extending in the axial direction from one to the other end face. The recesses produce sections which are opposite each other at a distance and continue into each other, forming a current path as a resistance heating element. The stabilization part at least partially fills the recess and mechanically couples the sections to each other, but does not electrically couple them to each other.

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: A purification component comprises at least one block for purifying exhaust gases, and a casing that defines a circulation channel for the exhaust gases extending along a longitudinal axis, and in which the purification block is housed. The casing comprises an inlet portion, an outlet portion, and a central portion arranged between the inlet portion and the outlet portion, and with the central portion surrounding the purification block. A thermal insulator covers the whole of the casing. The thermal insulator comprise a first part, having a first temperature resistance, arranged radially facing the purification block, and a second part, having a second temperature resistance greater than the first temperature resistance, covering at least the inlet portion of the casing.

Abstract: An electrically heated catalyst has a catalyst body and a housing at least circumferentially surrounding the catalyst body. An electrical contacting assembly is arranged on a shell surface of the catalyst body, the electrical contacting assembly comprising a surface electrode arranged directly on the catalyst body and a contacting element connected to the surface electrode. The contacting element is rigid and has a screw thread.
