ABSTRACT:
A device detects an air-fuel ratio of a fuel mixture by causing an electric current to flow through an oxygen ion-conductive solid electrolyte to cause migration of oxygen ions between an atmospheric air and a gas receiving portion into which the exhaust gases resulting from combustion of the fuel mixture are diffused via gas diffusion restricting means. The device includes means for detecting the electric current.
