ABSTRACT:
A soot filter for diesel-powered vehicles has two diesel particle filters which are connected to a preliminary muffler via separate ducts, which open radially into a filter prechamber. The exhaust gases can be sent through one of the diesel particle filters or the other by a damper control device, with the dampers being arranged far away from the filters, in the vicinity of the preliminary muffler. Thus, the dampers are located at a fairly great distance from the burner, which is arranged on the front side of the diesel particle filter, and which is designed such that it produces an approximately disk-shaped flame that is directed toward the front side of the diesel particle filter.
