ABSTRACT:
Method and apparatus for regenerating a particulate filter of a diesel engine. Disclosed is a particulate filter that, at all operating points of the diesel engine, can be regenerated by means of a burner working in the main engine exhaust stream. Regeneration is achieved by means of a burner (3) to which fuel and oxygen-containing gas is supplied in a variable proportion. By this means, the burner can produce the output required to achieve the regeneration temperature at any operating point of the diesel engine. The apparatus is suitable for diesel engines having thermally regenerable particulate filters.
