| 摘要 |
A combined oxygen and NOx sensor is provided. Generally, the combined sensor employs a sensor body (220) that includes two different types of electrodes - oxygen-porous electrode layers (16a, 16c) and dissociative oxygen-porous electrode layers (16b, 16d). In accordance with one embodiment of the presen t invention, the sensor comprises a sensor body, an oxygen content electrical signal output, and a NOx content electrical signal output. The sensor body i s disposed in the gas and comprises a plurality of oxygen-porous electrode layers and a plurality of dissociative oxygen-porous electrode layers. The dissociative oxygen-porous electrode layers comprise a material selected to dissociation of NOx into nitrogen and oxygen.
