Abstract: PROBLEM TO BE SOLVED: To provide an exhaust after-treatment filter capable of preventing hot spot meltdown from occurring. SOLUTION: This filter and method for after-treatment of exhaust are used for filtrating exhaust emission from an engine. Varing cell size is provided to distribute trapped contaminated particles along a distribution pattern for reducing the risk of melting of trapped contaminated particulates during heat concentration and regeneration or minimize the possibility of hot spot meltdown caused by the densely concentration of the trapped particulates. The cell size can be varied by varying a volume and/or a height and/or a width and/or a length. Tapered cell provides a change in cross sectional area at an upstream end part toward a downstream end part.

Abstract: PROBLEM TO BE SOLVED: To provide a high-temperature composite ceramic filter applicable as a filter for exhaust gas of a diesel engine. SOLUTION: This high-temperature commposite ceramic filter medium consists of large numbers of ceramic fibers, which are arranged at random and the surfaces and the crossing parts of which are coated with silicon carbide, and has high-temperature withstanding property, durability and improved performance. The composite ceramic filter medium is obtained by forming a sheet from the slurry containing a ceramic fiber, an organic fiber and a water-soluble thermoplastic binder, drying the sheet, fabricating the dried sheet into a three- dimensional green filter structure, applying any of the aqueous solution of a thermosetting resin and the colloidal solution of a ceramic material to the filter structure for enhancing the thermal stability of the green filter structure by hardening the binder, firing the obtained filter structure at the high temperature enough to remove the organic component and coating the fired filter structure with silicon carbide by chemical vapor deposition method.

Abstract: An exhaust aftertreatment filter has a pre-stressed layer bonded to the filter body at the outer periphery and compressively axially pre-stressed in an opposite axial direction to separational axial tensile stress to counteract the latter during regenerative heating, to minimize separational fracture and cracking.

Abstract: A high temperature composite ceramic filter having particular use as a diesel engine exhaust filter. An aqueous slurry containing short ceramic fibers, organic fibers and a water soluble thermoplastic binder is formed into a sheet and dried. The dried sheet is then fabricated into a three-dimensional green filter structure and a binder, either a liquid solution of a thermosetting resin or a colloidal solution of a ceramic material, is applied to the filter structure to increase the temperature stability of the green structure. The filter structure is then fired at an elevated temperature sufficient to remove the organic constituents and is subsequently coated with silicon carbide by a chemical vapor deposition process to provide a composite ceramic filter having high temperature resistance, durability and improved performance.

Abstract: An exhaust aftertreatment filter and method is provided for filtering engine exhaust. Varying cell size is provided to spread trapped contaminant particulate along a distribution pattern reducing heat concentration and the risk of melting during regeneration, to minimize hot-spot meltdown otherwise caused by high density concentration of trapped particulate during regeneration. Cell size is varied by varying volume and/or height and/or width and/or length. Tapering of cells is also provided to change the cross-sectional area from the upstream to the downstream end.
