ABSTRACT:
A soot filter adapted to be arranged in an exhaust gas stream of air-compressing internal combustion engines. The soot filter includes a cylindrical filter housing arranged in proximity of the exhaust gas stream of the internal combustion engine with inlet pipe connecting studs from outlet side of the internal combustion engine being connected to the cylindrical filter housing. A ceramic material of a hollow cylindrical shape is arranged in the filter housing at a distance from a circumferential wall of the filter housing. The ceramic material consists of an outer layer of loose ceramic fiber wadding and of inner woven ceramic fiber matting. A hollow space inside of the ceramic fiber material is connected, in an axial direction, with exhaust gas line of the internal combustion engine.
