Filtering sturcture, particularly a particle structure for the exhaust gases of an internal combustion engine and exhaust line associated therewith

摘要

Said structure comprises first and second filtering elements (15A, 15B) respectively comprising a first and second lateral surface (24A, 24B) disposed opposite each other. A joint (17) linking said surfaces (24A, 24B) extends between the surfaces (24A, 24B). The first lateral surface (24A) comprises, in the upstream part (36A), a first region (35C) of low or zero adherence with the joint (17), said region being defined longitudinally upstream by an upstream region (33A) of high adherence with said joint (17). The upstream region (33A) of high adherence is longitudinally defined upstream by a second region (35A) of low or zero adherence with the joint (17). Application: particle filters for the exhaust gases of an engine.
