Abstract

PURPOSE: The captioned detector for controlling the air-to-fuel ratio of internal combustion engines wherein the delamination of electrode form the surface of the oxygen concentration detecting element and its consumption are prevented despite repetition of cooling and heating cycles by providing a porous heat-resisting metal oxide film containing a conductive material on the detection gas side, is obtained.
