摘要：
The invention relates to a means and a method for removing soot in an exhaust gas filter of an internal combustion engine, more especially a diesel engine, by reducing the ignition temperature during the operation of the internal combustion engine. For this purpose, the ignition is brought about by the addition of at least one oxidizing agent. A plurality of particles of at least one combustible substance may also be caused to flow or burn, and the particles may be passed through the exhaust gas stream to the filter, so that the soot layer is ignited.
