An electrical heating unit H for introduction into the exhaust gas system of an internal combustion engine, in particular upstream with respect to an exhaust gas purification unit, for instance a catalytic converter, which for its operation requires a temperature higher than the ambient temperature, comprises a casing () and at least one resistance heating element () which is designed as a band and is retained inside the casing (), wherein the at least one heating band () is arranged so that it runs in a meandering pattern and with its flat face parallel or substantially parallel to the longitudinal axis of the casing (). The heating unit H also comprises at least one support structure () which is arranged on the end face relative to the heating band () and mechanically connected to the casing () and has slot-shaped heating band bearings () to retain the heating band () inside the casing (), into which slot-shaped heating band bearings () the heating band () engages by an edge portion and via which support structure () the heating band () is electrically insulated from the casing ().

In a particle filter for exhaust gases of internal combustion engines, particularly Diesel engines, including a filter body with filter pockets which are formed from sinter metal sheets and are wedge-shaped with an opening at the blunt end and edges formed by converging pocket side walls and arranged adjacent one another such that, between adjacent filter pockets, corresponding opposite spaces are formed with openings facing in a direction opposite to the openings at the blunt end, the filter pockets side walls are spaced from one another by widening means extending along at least an edge of the filter pockets so as to increase the width of the space between the side walls of the filter pockets.

In a particle filter with carbon (soot) deposit combustion for Diesel engines comprising a filter with filter areas of sinter metal through which exhaust gases from the Diesel engine are conducted to remove the soot therefrom, the soot collected at the raw gas side of the filter surfaces is burned off by radiation heaters which are arranged so as to radiate between wedge-like filter pockets of the particle filter such that selected areas of the filter are heated to initiate combustion of the soot on the filter surfaces.
