摘要： An exhaust particulate filter for an engine system includes an array of filter cartridges positioned within a shell, each of the cartridges having an electrically powered heating element coupled therewith. Exhaust gases may be distributed among the cartridges according to a single distribution pattern, and the filter can be regenerated without diverting, dividing or bypassing exhaust gases from the filter. The filter cartridges may be cylindrical or wedge-shaped, or of a variety of other configurations. Regeneration may take place according to a non-axial regeneration propagation profile. Other aspects include feedback control and feedforward control of regeneration based on sensing an electrical resistance property of each of the electrically powered heating elements.

摘要： A porous cordierite ceramic and a process for making the same are provided by the present invention. Preferably, the ceramic material includes at least about 95 percent cordierite in the crystal phase, a porosity of at least about 30 volume percent, a crush load strength of at least about 6 pounds, and a thermal conductivity of less than about 5 watts/meter-.degree.K. The method of producing a porous cordierite ceramic includes (a) combining alumina, clay, talc, a pore-forming material and preferably free silica; (b) adding binder, water and other additives; and (c) shaping the mixture to form a green body. The green body is thereafter fired to form a sintered ceramic body. The porous cordierite is useful in a heat source retainer.

摘要： A low cost process for self-forming a uniformly adherent protective rare earth silicate coating on a silicon-based ceramic component for protecting the component against corrosive/erosive environments. The coating is self-formed by an oxidation process of a silicon-based ceramic associated with a reaction between a silica (SiO2) film layer on the surface of silicon-based ceramic and the rare earth oxide existing inside of silicon-based ceramic component.

摘要： The present invention provides an aluminum borate ceramic having a high porosity and a tightly controlled pore size distribution, while maintaining good mechanical strength. The ceramic body can be formed by decomposing boric acid-stabilized aluminum acetate to form an aluminum borate powder, and sintering the powder to form a ceramic body.
