METHODS FOR CONTROLLING AND MAKING PARTICLE FILTERING DEVICES

摘要

The invention concerns a method for controlling the robustness of a particulate filter for use on a Diesel engine exhaust line, including the following steps which consist, after previously determining the threshold weight of soot of said filter, in loading a new filter with a soot level not less than twice and not more than three times said threshold weight of soot, then, in any order, determining the efficacy of said filter, measuring its pressure loss and comparing same to the pressure loss of the new filter, measuring its cracking level, and finally controlling its integrity after mechanical biasing. The invention also concerns a method for diagnosing the robustness of a filter.
