Abstract

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.
