Burner and method for removal of accumulated soot on a soot filter in internal combustion engines

摘要

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.
