Abstract: A particulate filter having a honeycomb structure of a matrix of interconnected porous walls including inlet cells and outlet cells defining a plurality of inlet channels and outlet channels, respectively, wherein at least a portion of the outlet cells are larger than any of the inlet cells, and a cross-sectional shape of at least some of the outlet channels is rectangular. Honeycomb extrusion dies, honeycomb bodies, honeycomb structures, and methods of manufacture are described, as are other aspects.

Abstract: Methods for forming an electrode for use in forming a honeycomb extrusion die. The method includes forming, by means of an additive manufacturing process, an electrode includes a base having a web extending from the base. The web defines a matrix of cellular openings. The method further includes forming a secondary electrode having a plurality of pins. The plurality of pins are shaped and arranged so as to mate with the matrix of cellular openings defined by the web of the electrode. The method further includes machining the electrode using the secondary electrode to smooth surfaces of the electrode formed by the additive manufacturing process.

Abstract: A method and extrusion die to form a laminar integral skin of a honeycomb structure is provided. The method includes extruding a ceramic precursor batch through a die with feedholes in entry side and slots in exit face of the die to form the honeycomb structure. In a region on the periphery of the die configured to form the cell matrix, a series of concentric slots around the matrix in the exit face of the die are configured to feed skin onto the matrix. Ring sections between concentric slots are angled away from the center and a mask is disposed on top of the periphery producing a channel for extruded skin to meet and bond to extruded matrix. Optionally, slots in the skin-forming ring sections enhance knitting between laminar skin layers.

Abstract: Ceramic honeycomb bodies and methods for canning the bodies are disclosed herein. The honeycomb bodies comprise a porous ceramic honeycomb structure. The honeycomb structure comprises a network of cells defined by walls that extend in an axial direction about a longitudinal axis from an inlet end to an outlet end of the honeycomb structure. The honeycomb structure also comprises a portion of cells with protrusions. The portion of cells with protrusions supports a greater concentration of catalyst, as compared to a portion of cells without protrusions. The portion of cells with protrusions is disposed off-center with respect to the longitudinal axis of the honeycomb structure such that the portion of cells with protrusions (and greater concentration of catalyst) corresponds to areas of high exhaust flow through the structure.

Abstract: Extrusion dies and methods of manufacturing extrusions dies, the extrusion die including a first plate and a second plate. The first plate has first upstream and downstream surfaces. A first material of the first plate has a first elastic modulus. The first plate includes pins formed between a plurality of slots. The pins and slots define a discharge face for the extrusion die at the first downstream surface of the first plate. The second plate has second upstream and downstream surfaces. The second plate is joined at the second downstream surface to the first upstream surface of the first plate. A second material of the second plate has a second elastic modulus. The second elastic modulus is greater than the first elastic modulus. A plurality of feed holes extend from the second upstream surface of the second plate through the extrusion die into communication with the slots.
