    摘要: This structure (11) comprises first and second filtering elements (15A, 15B) extending essentially parallel to a longitudinal axis (X-X′) of the structure (11) between an admission region (21) of the gases into the structure (11) and an evacuation region (23) of the gases from the structure, and comprises a seal (17) for joining these elements (15A, 15B). The seal (17) comprises at least one downstream pat (43) which has a thermal mass per unit length greater than the thermal mass per unit length of an upstream part (41) of the seal (17). The invention is for use in particulate filters for the exhaust gases of a motor vehicle diesel engine.

    摘要: A filter body (3) which is intended, in particular, for the filtration of particles contained in the exhaust gases from an internal combustion engine. The filter body (3) is formed by bonding filter blocks (11) using a joint (17). An outer surface (16) of the first of the blocks (11), which is disposed opposite the second of the blocks (11) and which is in contact with the joint (17), includes at least one projection- and/or cavity-type irregularity (30a, 30b).

    摘要: A block for filtering particles contained in an internal combustion engine exhaust gases, includes overlapping assemblies of adjacent input channels (14e) and output channels (14s), the input and output channels being alternately arranged so as to form, in cross-section, a checkered pattern, the overall volume of the input channels (14e) being greater than that of the output channels (14s). The filtering block is characterized in that at least one inner space (20e, 20s) of one channel (14e, 14s) includes at least one inner fin (30).

    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.
