ABSTRACT:
A process for the oxidation of a concentration of internal combustion engine emission particulates collected in a particulate filter trap by supplying secondary energy to the deposit at the inlet surface of the filter and/or to the particulate/exhaust gas mixture, includes adjusting the particulate concentration to a value which lies within the explosive range of the particulate/exhaust gas mixture by briefly adding, or recycling, combustible particulates to the exhaust gas flow in the filter, especially in front of the inlet face of the filter.
