Abstract

L'invention concerne un filtre en nid d'abeilles (1) qui est pourvu d'un corps principal de filtre (2), de cellules d'entrée multiples (3) et de cellules de sortie multiples (4). Les cellules d'entrée multiples (3) et les cellules de sortie multiples (4) sont disposées dans une matrice ayant au moins douze rangées et douze colonnes. Chacune des cellules d'entrée multiples (3) est adjacente à au moins une des cellules de sortie (4) avec un mur de séparation (9) interposé entre elles. Un rapport d'aire d'ouverture (A1/B1) de l'aire d'ouverture totale (A1) des cellules d'entrée multiples (3) dans une première surface d'extrémité (5) à l'aire d'ouverture totale (B1) des cellules de sortie multiples (4) dans une seconde surface d'extrémité (6) est supérieur à 1,0.
