    摘要: A strengthened thin-walled catalytic converter substrate includes thin perimeter walls and thin interior walls defining cells and a catalyst washcoat selectively disposed on the substrate. Washcoat thickness is increased in those cells having the most impact on final catalyst strength, typically the outer cells defined by the perimeter walls. A method for maximizing overall catalyst strength with minimal substrate thermal mass includes selectively applying washcoat based on desired substrate strength and converter assembly method.

    摘要: A non-thermal plasma reactor and method provides individually retained reactor plates. The method comprises stacking an alternating sequence of positive and negative reactor plates to form a reactor stack, placing temporary spacers between the positive and negative reactor plates. In one embodiment, individually retained reactor plates are secured by folds of a ceramic insulating layer extending between plate pairs, with reactor plates secured by the stack retention material and the folds of the ceramic insulting layer. In a second embodiment, individually retained reactor plates are secured with a permanent pleated insulting mica separator disposed on each side of the reactor. In a third embodiment, a retention material extends slightly into the exhaust gas passage at each side of the stack supplying permanent support for the stacked plates.

    摘要: A method of manufacturing an exhaust control valve includes casting first and second subhousings as separate pieces and machining smooth the inner faces of both. Each subhousing has a stem portion and a flow portion. Each flow portion defines a cylindrical bore from which a seat arc extends radially inward and approximately 180° along. The seat arc of the first subhousing lies below, and the seat arc of the second subhousing lies above, a horizontal plane that bisects the subhousings. Each seat arc has a semicircular inner sidewall that serves as a valve seat. Their inner faces facing each other, the two subhousings are mated so that their two stem portions form a stem housing and their two flow portions form a flow housing. During the mating step, the cylindrical bores are aligned to form a flow passage through the flow housing, with the two valve seats spaced equidistantly from a vertical plane defined by the inner faces along which the subhousings mate. In further steps, the method involves boring at least one bore into the stem housing. A rotatable shaft is sealingly enclosed within the bore(s) and it protrudes into the flow passage. Another step entails affixing the valve plate to the shaft so that it will pivot between the opened and closed positions as the shaft is being rotated accordingly.

    摘要: A vehicular catalytic converter (10) is disclosed having a plurality of catalytic monoliths (24,26). The first (24) and second (26) catalytic monoliths are connected to each other at an angle. Any number of catalytic monoliths may be serially connected at angles to increase the gas-to-catalyst contact within the catalytic converter (10) thus creating a more efficient catalytic converter.
