Abstract

It was developed the oxygen sensor of air-fuel ratio measuring system that was controlled the needed air amounts in optimum combustion according to the analysis of oxygen concentration of exhaust gas. The oxygen sensor was prepared by using gold as cathode, which the detection range for the oxygen concentration was from 0.0% to 30.0%. Response time was observed 15 to 20 sec. rapidly and selectively. It was appeared a good result in reproducibility and stability.
