Filter element for filter device for filtering exhaust gases of internal combustion engine, has longitudinal axis running parallel to main flow direction of exhaust gas, multiple entry channels and multiple exit channels

摘要

The filter element (18) has a longitudinal axis (26) running parallel to main flow direction of exhaust gas, multiple entry channels (28), and multiple exit channels (30). The entry channels and exit channels are bounded by filter walls (31), and the filter walls are provided with a coating. The coating contains inflammable polymers, carbon fibers, graphite fibers or carbon nanotubes. The filter wall is made from aluminum magnesium silicate, particularly titanium dioxide, silicon carbide or aluminum titanate.
