ABSTRACT:
An apparatus for removing solid particles, especially soot particles, from the exhaust gases of an internal combustion engine includes a separator that divides the flow of exhaust gases into a largely particle-free primary flow and a particle-enriched secondary flow. The secondary flow is delivered to a disposal device, which has a combustion chamber and a pilot burner for producing a flame that burns off the solid particles. To improve the efficiency of the apparatus by reducing the heating output required, a filter is provided in the combustion chamber, which divides the combustion chamber into a filter pre-chamber and after-chamber. The burnoff flame of the pilot burner burns into the filter pre-chamber, and the burnoff gases are removed via an outlet opening disposed in the filter after-chamber. The secondary exhaust gas flow is delivered to the filter pre-chamber with a tangential inflow direction.
