Abstract:

A honeycomb body having intersecting porous walls and repeating structural units. Each repeating structural unit has a plurality of inlet channels and outlet channels that extend parallel to each other in an axial direction from an inlet face to an outlet face. Each of the repeating structural units has 2.0<I/O<3.0, wherein I/O is a ratio of a number of inlet channels to a number of the outlet channels, each of the inlet and outlet channels have a same cross-sectional size and shape, and each inlet channel of a particular repeating structural unit directly abuts an outlet channel of the particular repeating structural unit or an outlet channel of an adjacent repeating structural unit. Particulate filters including the honeycomb body, honeycomb extrusion dies, and methods of capturing soot in the honeycomb body are provided, as are other aspects.
