    摘要: An air-fuel ratio detecting element is composed of an oxygen pump portion and an oxygen sensor portion which are provided on a single solid electrolyte sheet, a heating element, and a spacer. The oxygen pump portion is composed of a pair first of electrodes provided on opposite sides of the solid electrolyte sheet, and a communication hole which is formed through the solid electrolyte sheet and the electrodes. Electrodes are disposed on the solid electrolyte sheet on the same side as the second electrode, whereby the oxygen sensor portion is formed. The spacer has an opening and a slit-like opening. The heating element 4, the spacer, and the solid electrolyte sheet are stacked from bottom to top, and then the stacked assembly is baked. In this case, they are stacked such that the opening faces the first electrodes and the second electrode. By disposing the oxygen pump portion and the oxygen sensor portion on the same solid electrolyte sheet, structure can be made simpler compared with a conventional air-fuel ratio detecting element in which a solid electrolyte sheet is used for each of an oxygen pump portion and an oxygen sensor portion.

    摘要: A catalyst-loaded ceramic filter made of a ceramic material capable of directly supporting a catalyst component thereon is capable of providing early activation of the catalyst with a low coefficient of thermal expansion and light weight, without compromising the high porosity of the filter substrate. A catalyst-loaded ceramic filter is made of a ceramic material of which one or more kinds of element among its constituent elements is substituted with an element other than the constituent elements, for example a ceramic material with a part of Si or other elements included in cordierite is substituted with W or Co, as a filter substrate of honeycomb structure having a number of cells separated by porous walls, and supporting a catalyst such as a noble metal directly on the W.

    摘要: A main body of a NOx sensor has a sensor cell and defines a reference gas chamber and a sample gas chamber therein. The sample gas chamber has a wall formed by a solid electrolytic substrate having an oxygen ion conductivity. The sensor cell is disposed between the reference gas chamber and the sample gas chamber for detecting a concentration of a NOx gas. A pump cell body of the NOx sensor has a surface facing to the sample gas chamber and has a pump cell for introducing and exhausting an oxygen gas to and from the sample gas chamber. In manufacturing this NOx sensor, the main body and the pump cell body are fabricated individually as separate items. The main body and the pump cell body are sintered independently. Then, the main body and the pump cell body are assembled into to the NOx sensor.
