摘要： A ceramic wall-flow filter for filtering particulate matter from gases and methods for manufacturing such wall-flow filters are disclosed. The filter includes an array of porous ceramic walls defining a pattern of end-plugged inlet and outlet cells, and heat absorbing elements disposed within at least some of the outlet cells such that a bulk heat capacity of the outlet cells is greater than a bulk capacity of the inlet cells. The heat absorbing elements increase a bulk heat capacity of the filter without substantially interfering with a flow of gas through the porous ceramic walls by allowing thinner walls. According to the method, during the step of extruding or thereafter, heat absorbing elements are formed within at least some of the outlet cells such that a heat capacity of the outlet cells is greater than the inlet cells.

摘要： A radial cell ceramic honeycomb structure is provided that is particularly adapted for use as a catalytic carrier or a particulate filter in an automotive or diesel exhaust system. The honeycomb structure includes a network of interconnected webs having a central axis. The network of webs includes radial webs of varying lengths, only some of which substantially extend the entire radial length of the network, and tangential webs that intersect to define rings of gas-conducting radial cells, and a rounded outer skin that surrounds the cells formed by the interconnected webs. The radial webs extending to the periphery of the network join an inner edge of the outer skin in a substantially orthogonal orientation to reduce thermally generated stresses and to increase strength of the resulting structure. The number of radial webs in the network changes along the radial length at transition zones that are defined by one of the tangential webs such that a desired cell density is achieved across the network.

摘要： A method for forming honeycomb structures, such as wall-flow honeycomb filters, which utilizes extrusion of multiple material supplies at once. Such methods may be used to form intermittent plugs or other structures in the cell channels during the extrusion process, for example. A die assembly is provided which includes secondary feedholes machined in the pins for intermittently or periodically injecting secondary material (e.g., plug material) into the cell channels of the honeycomb structure while it is being extruded.

摘要： Extruded metal honeycombs are produced by the direct extrusion of a softened bulk metal feedstock through a honey-comb extrusion die comprising a feedhole array for delivering softened metal through a supporting die baseplate to a honeycomb die discharge section, the discharge section comprising an array of intersecting discharge slots that form the walls of an extruded metal honeycomb structure. This process can be optimized by employing a proper pressure gradient for a particular extrudate flow rate, extrudate composition, and wall-drag condition arising from the particular composition of the feedhole wall, as illustrated graphically in FIG. 4.
