Abstract
A process for the combustion treatment of carbonaceous particles collected on a filter situated in an exhausted circuit of an internal combustion engine is disclosed. The combustion of the particles is brought about by contacting them with a gas mixture including at least nitrogen dioxide generated within the exhaust circuit of the engine, the particles having been seeded prior to their combustion with at least one catalyst of their oxidation.
