Abstract:
A soot particle filter according to the invention can be particularly used in motor vehicles or heating systems using liquid and solid fuels. The device is particularly characterized by a time controlled variable regeneration of the soot particle storage (10) and soot particle burn-off. The device is in particular catalytic. The device comprises at least one filter housing (2) having an input (3), an output (4) and a filter element (6). A soot particle storage chamber (10) is further provided in the filter housing (2) and comprises an access (19) that is particularly angled and tapered toward the inside. The inner chamber of the soot particle storage (10) is lined with precious metal discs (11). Said discs have holes, are angled and/or corrugated. The precious metal discs and/or a precious metal mesh (11) are at least partially catalytically coated. An ignition device (12) is arranged in the filter housing (12), for example a glow plug and/or a glow filament.
