The method optimizes the combustion of harmful soot particles over a wide range of temperatures by pre-seeding the filtered particles with an oxidation catalyst prior to their combustion in a gas containing nitrogen dioxide. The combustion is achieved at a temperature lower than is necessary for particles seeded with an oxidation catalyst and for unseeded particles. A new process for the combustion of carbonaceous particles collected on a filter which is placed in the exhaust circuit of an internal combustion engine. The combustion is effected by contacting them with a gaseous mixture containing nitrogen dioxide generated within the exhaust system, the particles having been pre-seeded with an oxidation catalyst. |
