    摘要： An exhaust gas sensor includes a first electrode, a second electrode, and an electrolyte disposed between the first electrode and the second electrode. The electrolyte includes a first portion disposed at least in partial physical contact and in ionic communication with a second portion. The first portion has a first portion grain size which is different than a second portion grain size. Further, a method for manufacturing a gas sensor includes forming a multiple portion electrolyte. The electrolyte is formed with a first portion having one grain size, and a second portion at least in partial physical contact and in ionic contact with the first portion, the second portion having a second portion grain size different from the first portion grain size. The electrolyte may be fired before or after application of an electrode in ionic contact with the first portion and a second electrode in ionic contact with said second portion.

    摘要： The torch jet spark plug comprises a shell with an insulator body concentrically disposed within at least a portion of the shell. A pre-chamber is concentrically disposed within at least a portion of the shell and at least a portion of the insulator body, the pre-chamber having an orifice disposed at a first end of the pre-chamber and at an insulator body first end. On at least a portion of a pre-chamber internal surface is an inner electrode comprising up to about 75 vol. % of a bonding agent, about 20 vol. % or greater of a catalytically active material, and about 5 vol. % or greater of a transition metal material. At least partially disposed within a second end of the insulator body, opposite the insulator body first end is an upper terminal. Finally, an upper electrode is disposed within the insulator body, between the inner electrode and the upper terminal, and in a spaced relation to the inner electrode.

    摘要： A catalyst for preferentially reducing carbon monoxide in a hydrogen stream. The catalyst is formed from a chemical composition including a hexaaluminate, a metal hydroxide and a precious metal. The composition may be disposed on a support or may be extruded or cast into or onto a support. Incorporation of hexaaluminates allows inclusion of metal hydroxides that flux the active precious metal surface at higher temperatures than can aluminum oxide-based catalytic compositions, thereby enhancing resistance of the catalyst and monolithic support and increasing the durability and thermal range of the PROX catalyst. An additional advantage is that lesser amounts of precious metal oxides need be deposited onto the hexaaluminate, while retaining activity similar to aluminum oxide compositions.
