Abstract:
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.
