FILTERING BODY COMPRISING A PLURALITY OF FILTERING UNITS, IN PARTICULAR DESIGNED FOR A PARTICULATE FILTER

摘要

The invention concerns a filtering body (3), in particular for a motor vehicle internal combustion engine exhaust gas particulate filter (1), comprising a plurality of filtering units (11a-11i) assembled by at least a joint (12) interposed between the filtering units (11a-11i) and configured so as to counter the passage of exhaust gases between the filtering units (11a-11i). Said filtering body is characterized in that the joint (12) comprises a plurality of joint portions (12a-12e) locally adapted to optimize the attenuation of thermomechanical stresses liable to be generated in the filtering body (3).
