    摘要: A device for sensing the oxygen concentration in an exhaust gas has a cup-like oxygen-ion permeable cylindrical member made of solid electrolyte consisting of oxygen-ion conducting metal oxide. The cylindrical member has an inner circumferential surface communicating with the atmosphere and an outer circumferential surface communicating with the exhaust gas for producing an electromotive force corresponding to a difference between the oxygen concentrations on the inner circumferential surface and on the outer circumferential surface and has a negative-resistance temperature characteristic. A pair of first electrodes serving as a lean sensor each comprise a thin film made of porous metal material and are provided on the inner circumferential surface and outer circumferential surface of the cylindrical member, respectively, in opposed relationship to each other. An oxygen-gas diffusion limiting layer covers the lean sensing electrode on the outer circumferential surface of the cylindrical member. A pair of second electrodes for sensing the oxygen concentration under high load drive mode and the temperature of the cylindrical member each comprises a thin film made of porous metal material and are provided, respectively, on those portions of the inner and outer circumferential surfaces of the cylindrical member which are different from the portions where the first electrodes are provided in opposed relationship to each other. A heater is disposed in the cylindrical member for heating the cylindrical member.

    摘要: An oxygen concentration sensing apparatus in which a block of an oxygen-ion conductive solid electrolyte is interposed between a first electrode and a second electrode disposed opposite to each other. The first electrode is made of a catalytic metal and is exposed at a portion thereof on a surface of the solid electrolyte block, and an electrical insulating heat-resistive layer having a plurality of communication pores covers the exposed portion of the first electrode. The second electrode is porous and made of a catalytic metal. The solid electrolyte is wholly exposed to a stream of gases containing oxygen whose concentration is to be measured, and during measurement, a current source supplies continuously an electric current in a direction from the first electrode toward the second electrode. When the partial pressure of oxygen gas produced at the first electrode and existing in the vicinity thereof exceeds a predetermined value, the excess pressure portion of oxygen gas is discharged into the stream of gases through the communication pores of the heat-resistive layer thereby maintaining substantially constant the partial pressure of oxygen gas in the vicinity of the first electrode. An electromotive force representing the ratio between the partial pressure of oxygen around the first electrode and that in the stream of gases containing oxygen is measured to determine the concentration of oxygen contained in the gases.
