摘要： A breath sensor (1) includes a heat exchange portion (41) that allows heat exchange between breath discharged from a second chamber C2 and breath introduced into a first chamber C1. Therefore, breath introduced into the first chamber C1 can be heated by breath discharged from the second chamber C2, to increase the temperature of the introduced breath. Since the temperature of the breath is increased, an effect of reducing power consumption of a heater (29c) in heating a conversion portion (21) and a detection portion (29a) is realized. The heater (29c) heats both the conversion portion (21) and the detection portion (29a) to a temperature in an operation or activation temperature range. Further, power consumption for heating to an operation temperature can be reduced by preheating the introduced breath as described above.

摘要： The present specification provides a NOx responsive element suitable for directly sensing NOx. The NOx responsive element an oxygen ion conductive layer has a first electrode layer having a nitrogen oxide decomposition catalyst phase composed of perovskite-type oxide, being in contact with the oxygen ion conductive layer, and being exposed to NOx, and a second electrode layer opposing the first electrode layer across the oxygen ion conductive layer. The nitrogen oxide decomposition catalyst phase has a nitrogen oxide adsorption stabilizing surface on its surface exposed to nitrogen oxide.

摘要： Diagnostic processes for determining whether a NOx sensor is in a stuck-in-range failure mode may be performed when the NOx sensor reaches an operational temperature and before the oxygen pumps of the NOx sensor are activated and/or during operation. The processes may include interpreting values of a parameter indicative an amount of O2 and/or NOx measured by the NOx sensor. The processes include determining if the values of the parameter exceed a threshold value and indicating a failure of the NOx sensor responsive to the values not exceeding the threshold value. In some implementations, the processes may include increasing an amount of O2 in a chamber of the NOx sensor. Increasing the amount of O2 in the chamber of the NOx sensor may include deactivating an oxygen pump of the NOx sensor or reducing an amount of O2 removed via an oxygen pump of the NOx sensor.

摘要： A gas sensor includes a sensing element having an electrode pad a metal terminal, and a separator that has insertion holes in which the metal terminal is held. The metal terminal includes a main body and an elastic portion that is integrally connected to the main body and is elastically connected to the electrode pad at a predetermined contact point. The main body includes a front-end-side restricting portion and a rear-end-side restricting portion that restrict the movement of the main body by contacting wall surfaces of the insertion hole when the main body moves in a direction intersecting the direction of an axial line. The contact point is located between the front-end-side restricting portion and the rear-end-side restricting portion in the direction of the axial line. The front-end-side restricting portion and the rear-end-side restricting portion are connected to each other so that a flat board portion is interposed therebetween.
