    摘要： A block, particularly for filtering particulates present in the exhaust gases of an internal combustion engine, includes a plurality of flow channels for the gases (14e,14s), each of the channels (14e,14s) being bounded by a side wall (22), a plug (15e,15s) and an opening (19e,19s) terminating outwardly. The block according to the invention is remarkable in that a first portion (34) of the side wall (22) of at least one of the channels (14p,14p″), called the “reinforced channel”, includes a reinforcement compared to the rest of the side wall (22) forming a second portion (36) of the side wall (22), the ratio (R) of the thickness of the first portion (34) to the thickness of the second portion (36), in any transverse plane of section (P), being between 1.1 and 3.

    摘要： A filter block, particularly for filtering particulates present in the exhaust gases of an internal combustion engine, including peripheral inlet (50,14p2) and outlet (52,14p1) channels arranged alternately at the periphery of the block and each including an external wall (44;54;401,402;403) exposed to the exterior of the block and an internal wall (46;56;404,405;406,407,408) arranged inside the block. The block according to the invention is remarkable in that it includes at least one group (G) of two adjacent peripheral channels (50,52) such that, in a transverse plane of section (P), the ratio R of the average thickness “E” of all the external walls (44,54) of the group (G) to the average thickness “e” of all the internal walls (46,56) of the (G) is greater than 1.2.

    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.
