    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 device for aligning and/or assembling filtering elements, in particular of particulate filter, an installation for assembling a filter from filtering elements incorporating the device, and a method for aligning and/or assembling monolithic filtering elements, in particular for making a particulate filter. The device includes a back plate whereon are set the filtering elements, the back plate being for example fixed on a base plate, and walls laterally foldable upwards by a folding mechanism, such that the filtering elements are mutually maintained tightly when the walls are in an upper position.

    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.

    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.
