ABSTRACT:
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.
