Engine exhaust gas treatment article comprising a contoured honeycomb body () including a contoured outlet end face () are disclosed. Also disclosed are methods of manufacturing an engine exhaust gas treatment article.

Contoured honeycomb bodies

A coated ceramic honeycomb body comprising a honeycomb structure comprising a matrix of intersecting porous walls forming a plurality of axially-extending channels, at least some of the plurality of axially-extending channels being plugged to form inlet channels and outlet channels, wherein a total surface area of the outlet channels is greater than a total surface area of the inlet channels, and wherein a catalyst is preferentially located within the outlet channels, and preferentially disposed on non-filtration walls of the outlet channels. Methods and apparatus configured to preferentially apply a catalyst-containing slurry to the outlet channels and non-filtration walls are provided, as are other aspects.

Outlet-coated ceramic honeycomb bodies and methods of manufacturing same

A honeycomb structure () includes intersecting porous walls (). Inlet channels () and outlet channels () are formed by the intersecting porous walls (), wherein the inlet channels () comprise inlet hydraulic diameters (HDi) and the outlet channels () comprise outlet hydraulic diameters (HDo). The inlet channels () comprise inlet corners () with inlet corner radii (Ri) and the outlet channels () comprise outlet corners () with outlet corner radii (Ro). A centerpost () is defined by adjacent opposing inlet corners () of two of the inlet channels () and adjacent opposing outlet corners () of two of the outlet channels (). A first diagonal length (D1) is a shortest distance between the opposing outlet corners () of the two outlet channels () and a second diagonal length (D2) is a shortest distance between the opposing inlet corners () of the two inlet channels (). The honeycomb structure () has certain aspect ratios D1:D2 depending on hydraulic diameter ratios HDi:HDo.

High isostatic strength honeycomb structures and extrusion dies therefor

Methods of testing a honeycomb filter include the step of maintaining an average temperature of the honeycomb filter and/or fog within a range of from about 10&#xb0; C. to about 30&#xb0; C. and flowing a fog with moisture droplets into the honeycomb network of channels at the first end portion of the honeycomb filter, the fog including a relative humidity of at least 80%. In further examples, the moisture droplets include a mean droplet size of from about 1 micron to about 25 microns.
