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).
