A burner for cleaning accumulated soot from a soot filter associated with the exhaust of internal combustion engines, the burner is simple from a constructional viewpoint and especially effective with respect to initiation and maintenance of a soot-burning process in the soot filter. The burner includes a fuel nozzle, air nozzle, and glow plug arranged in a predetermined succession in the flow direction of the air introduced into the burner chamber. An especially intensive intermingling of the fuel-air mixture for the burner and/or for the soot filter is obtained by producing a turbulent flow by means of the air nozzle.

A system for burning off accumulated soot on soot filters associated with internal combustion engines comprising an internal combustion engine having an exhaust system, a soot filter disposed in the exhaust system downstream from the engine, and a burner connected to the exhaust system between the engine and the soot filter, the burner including a burner chamber, an annular chamber disposed around said burner chamber, means for injecting fuel into the burner chamber including a fuel nozzle, plug means for one of inducing heat to and causing ignition of a fuel-air mixture in the burner chamber, and means for conducting air having traversed through the annular chamber into the burner chamber, said means for conducting air including a tangentially disposed outlet orifice for introducing the entire amount of air employed in the burner chamber and located in the periphery of the burner chamber for inducing a generally swirling flow to the air being introduced into said burner chamber, the air orifice, the means for injecting fuel, the plug means being flow arranged one behind the other in the burner chamber in the flow direction of the air through the burner chamber, said annular chamber being disposed around the burner chamber in a manner such that air passing therethrough cools the burner chamber and is preheated prior to being conducted into the burner chamber through the outlet orifice.
