摘要： An air-fuel ratio sensor of a limit current type is used for an air-fuel ratio feedback control. When the air-fuel ratio sensor is in a semi-activated state, the air-fuel ratio sensor is driven into an electromotive force generating mode by a current externally applied thereto thereby to shift an electromotive force changing point so that an air-fuel ratio at which the electromotive force changes stepwisely is shifted from the stoichiometric ratio point to a lean zone. When the air-fuel ratio sensor is in a completely activated state, the air-fuel ratio sensor is applied with a voltage to produce a limit current varying with an air-fuel ratio so that a feedback control is performed based on the advanced control theory by using a linear current output characteristics.

摘要： An oxygen concentration sensor of this invention comprises an element and a diffusion hole. The element is exposed to a gas to be measured and has a chamber portion formed together with an oxygen ion conductive solid electrolyte. The diffusion hole is provided for restricting the flow of said gas to be measured into said chamber portion. Furthermore, the relationship 1.ltoreq.S/(L.multidot.V).ltoreq.5 is established with the diffusion hole having a cross sectional area S (mm.sup.2) and a length L (mm) and the chamber portion having a volume V (mm.sup.3). To do so, the oxygen concentration sensor can provide a stable output even if a pressure of the gas to be measured is abruptly changed.
