ABSTRACT:
An exhaust gas cleaning device for diesel engines has an exhaust gas soot filter (2) with a filter body (6) that is supported in a housing (4) and is regenerated by combustion of the soot when its temperature rises above the middle operating exhaust gas temperature range. A burner (26) is provided, having a combustion air fan (28) whose hot gas side is in flow communication with the exhaust gas soot filter (2), and the filter body (6) is supported in its housing in such a manner that at least a large part of its outer surface is heated externally during operation of the burner (26).
