Method for cleaning the upstream surface of a particulate filter |
摘要 |
The invention concerns a method for cleaning the upstream surface (14) of a particulate filter (10) of a heat engine exhaust line, the filter (20) being arranged in a casing (12) having an outlet (22) for exhaust gases. The method comprises a step which consists in circulating a liquid flux through the particulate filter (10) from its downstream surface (18) towards its upstream surface (14) viewed from the direction of exhaust gas flow in the filter. The liquid flux circulated through the particulate filter (10) has a flow rate higher than 50 litres/minute and is distributed over the main part of the downstream surface (18) of the particulate filter.
