PROCESS FOR OPERATING AN ENGINE SUPPLIED WITH A FUEL CONTAINING A CATALYST FOR REGENERATING A PARTICULATE FILTER

摘要

The invention relates to a process for operating an internal combustion engine of a vehicle equipped with an exhaust system comprising a catalysed particulate filter in which the engine is supplied with a fuel containing a catalyst for regenerating the particulate filter. The process is characterized in that the concentration of catalyst in the fuel varies discontinuously.
