Dieselpartikelfilter mit verbesserten Staudruckeigenschaften
The filter has flow channels (1) provided with a coating (6) made of high-melting material. The coating closes pores (5) for soot particles (7) in a wall (4) of a ceramic wall flow filter substrate without penetration of gaseous exhaust gas components. The pores connect flow channels and disperse channels (2) with each other. Particle sizes of the material are adapted to sizes of the pores such that a value of particle sizes distribution of the material is equal to or larger than a value of pores sizes distribution of the substrate. The coating includes a thickness of 10 to 150 micrometers.
