Title (EN) PATTERN-PLUGGED HONEYCOMB BODIES, PARTICULATE FILTERS, AND EXTRUSION DIES THEREFOR
(FR) CORPS EN NID D'ABEILLES À MOTIFS BOUCHÉS, FILTRES À PARTICULES ET FILIÈRES D'EXTRUSION POUR CEUX-CI
Abstract:
(EN) A honeycomb body having intersecting porous walls which includes first through fourth cells, wherein the cells extend from inlet to outlet face and are plugged to define a repeating structural unit with three inlets and one outlet channel. Repeating structural unit includes a first channel including length L1, width W2, and area A1, a second channel including length L2, the width W2, and area A2, a third channel including the length L1, width W1, and area A3, and a fourth channel including the length L2, the width W1, and A4, wherein the first through third channels are inlets and the fourth channel is a rectangular outlet and at least one of W1>W2 and L1≠L2, i.e. W1>W2, or L1≠L2, or W1>W2 and L1≠L2. Repeating structural unit has a quadrilateral outer perimeter. Particulate filters including the honeycomb body, honeycomb extrusion dies, and methods of manufacturing the honeycomb body are provided.
(FR) L'invention concerne un corps en nid d'abeilles ayant des parois poreuses qui se croisent, qui inclut des première à quatrième cellules, les cellules s'étendant d'une face d'entrée à une face de sortie et sont bouchées pour définir un motif structural répétitif avec trois entrées et un canal de sortie. Le motif structural répétitif inclut un premier canal incluant une longueur L1, une largeur W2 et une aire A1, un deuxième canal incluant une longueur L2, la largeur W2 et une aire A2, un troisième canal incluant la longueur L1, la largeur W1, et une aire A3 et un quatrième canal incluant la longueur L2, la largeur W1 et A4, les premier à troisième canaux sont des entrées et le quatrième canal est une sortie rectangulaire et au moins l'un de W1>W2 et L1≠L2, c'est-à-dire W1>W2, ou L1≠L2, ou W1>W2 et L1≠L2. Un motif structural répétitif a un périmètre externe quadrilatéral. L'invention concerne également des filtres à particules incluant le corps en nid d'abeilles, des filières d'extrusion de nid d'abeilles, et des procédés de fabrication du corps en nid d'abeilles.
