Abstract
The invention relates to a soot-particle filter for after-treatment of the exhaust gases of diesel engines by oxidation and the supply of thermal energy. Exhaust-gas-permeable supporting tubes extend in a filter housing and have an applied catalytic filter winding, via which exhaust gases flow radially from outside to inside into the supporting tubes. An exhaust-gas-permeable insert with a catalytically effective surface is arranged in each supporting tube to thereby enhance the effectiveness of the filter without increasing its overall size.
