    摘要： A catalytic converter has a cylindrical, monolithic catalyst element cylindrically enclosed and retained in a thin metallic sheath having ends extending to end portions of a case around openings therein so that the sheath substantially divides the internal volume of the case into an inner flow channel containing the catalyst element through which substantially all gas flow is directed and an outer volume separated from the catalytic element and retaining a heat insulating mat wrapped around the sheath. The sheath may be provided with a resilient structure at each end to engage the case and thus help support the catalyst element therein.

    摘要： A substrate assembly is stuffed into a converter outer shell to form a catalytic converter having a desired gap bolt density (GBD) value. The substrate assembly is formed by wrapping and taping a mat around a catalytic substrate. A predetermined pressure is applied to the substrate assembly and an outer diameter of the substrate assembly is measured at this predetermined pressure. A GBD value is predicted based on this measurement and if the GBD value is acceptable the substrate assembly is stuffed into the converter outer shell.

    摘要： “Noxious substances in the exhaust, including CO, NOx, and incompletely combusted hydrocarbons are converted to more benign substances through the action of the catalytic element, which is preferably a frangible ceramic honeycomb structure having a plurality of internal passages coated with a catalytically active substance.”“The tabulated ends minimize production of turbulence in the gas flow and allow the converter to be connected to the rest of the exhaust system by clamped, welded, or flanged joints. The one-piece, seamless construction of the converter is economical to produce and eliminates welding of housing components that tend to fail when subjected to corrosive exhaust gasses over a prolonged period of time.”

    摘要： A method and apparatus for assembling an exhaust treatment device such as a catalytic converter employs post calibration to achieve a desired bulk gap density of a support mat surrounding a substrate in the device housing. The mat is gauged under pressure to a thickness yielding the target bulk gap density and the pressure is saved for use in comprising the device housing against the mat after soft stuffing of the mat/substrate subassembly into the housing.

    摘要： A honeycomb structural body (1) is obtained by bonding, into one piece, a plurality of honeycomb segments (2a, 2b) having a plurality of through-holes (6) surrounded by partition walls (10) and extending in the axial direction. An average wall thickness of at least one honeycomb segment (2a) not constituting the outermost peripheral surface (23) of the honeycomb structural body is larger than an average wall thickness of at least of each honeycomb segment (2b) constituting the outermost peripheral surface (23) of the honeycomb structural body. A honeycomb structural assembly is obtained by providing a material B having compressive elasticity on the outermost peripheral surface (23) of the honeycomb structural body (1) in a compressed state and thereby compression-holding the honeycomb structural body (1) in a metallic container. The honeycomb structural body and assembly have low reduction in the conversion rate, purification efficiency, regeneration efficiency, etc., during use, and are superior in durability against breakage caused by thermal stress.

    摘要： An object of the present invention is to provide a honeycomb structural body with a long service life, which can reduce a pressure loss to a low level upon collecting particulates and maintain the pressure loss at the low level for a long time even after regenerating processes. The honeycomb structural body includes a columnar porous ceramic block in which a large number of through holes are placed in parallel with one another in the length direction with a wall portion interposed therebetween. Herein, the large number of through holes are constituted by a group of large-capacity through holes, each of which is sealed at one end of the honeycomb structural body so that the total sum of the areas on a cross section perpendicular to the length direction is made relatively great, and a group of small-capacity through holes, each of which is sealed at the other end of the honeycomb structural body so that the total sum of the areas on the cross section is made relatively small, and a surface roughness Ry of the wall face of the through hole is set in a range from 10 to 100 μm.

    摘要： There is disclosed a honeycomb structure (1) comprising: a plurality of honeycomb segments (2a, 2b), bonded into one piece, having a large number of cells (6) separated from one another by cell walls (10) and extending through an axial direction. At least one honeycomb segment (2a) not constituting an outermost peripheral surface (23) of the honeycomb structure (1) has a larger average cell wall thickness and a smaller or equal cell density compared with those of at least one honeycomb segment (2b) constituting the outermost peripheral surface (23). There is disclosed a honeycomb structure assembly in which a material B having compressive elasticity is disposed in a compressed state on the outermost peripheral surface (23) of the honeycomb structure (1) to compression-hold the honeycomb structure (1) in a metallic container. The honeycomb structure and assembly can prevent deterioration of reactivity, purification efficiency, and regeneration efficiency at the time of use, and can be low in pressure loss and better in durability against breakage by thermal stress.
