Abstract

The invention relates to a process for the discontinuous burning off of carbon deposited on the heat-resistant exhaust gas filter of an internal combustion engine, particularly a diesel internal combustion engine. At least one metal must be present during this process. The problem of ensuring the combustion of the carbon at the minimum temperature and of achieving a long filter life, is solved in a particularly advantageous manner through the use of an organic complexing agent able to form a complex with the metal and/or an organo-metallic complex compound of the metal with the organic complexing agent. The invention also relates to an apparatus for performing the inventive process. For this purpose, the exhaust gas filter preferably has at least two, at least temporarily separately operable filter units.
