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. |
