Title (EN) POROUS HONEYCOMB FILTER
(FR) FILTRE EN NID D'ABEILLES POREUX
(JA) 多孔質ハニカムフィルタ
Abstract: front page image
(EN) A porous honeycomb filter (1) having: porous first cell walls (21) permeable to exhaust gas; second cell walls (22) less permeable to the exhaust gas than the first cell walls (21); and cells (3) forming gas flowpaths that extend surrounded by the first cell walls (21) and the second cell walls (22). The second cell walls (22) have lower porosity than the first cell walls (21).
(FR) Un filtre en nid d'abeilles poreux (1) comprend : des premières parois cellulaires poreuses (21) perméables aux gaz d'échappement; des secondes parois cellulaires (22) moins perméables aux gaz d'échappement que les premières parois cellulaires (21); et des cellules (3) formant des chemins d'écoulement de gaz qui s'étendent entourées par les premières parois de cellule (21) et les secondes parois de cellule (22). Les secondes parois cellulaires (22) ont une porosité inférieure à celle des premières parois cellulaires (21).
(JA) 排ガスを透過させる多孔質の第1セル壁(21)と、第1セル壁(21)よりも排ガスを透過しにくい第2セル壁(22)と、第1セル壁(21)及び第2セル壁(22)に囲まれて伸びるガス流路を形成するセル(3)と、を有する多孔質ハニカムフィルタ(1)である。第2セル壁(22)は、第1セル壁(21)よりも気孔率が小さい。
