A thin film air-fuel ratio (A/F) sensor for wide range combustion control has been developed. This sensor consists of a limiting-current-type detective part for wide-range A/F, a resistive-type detective part for stoichiometric A/F and a heating part. The limiting-current-type detective part is operated by changing the polarity of the applied sensor voltage, and detects A/F from rich to lean range without an additional reference chamber for pumping or introducing oxygen. The operating mechanism in the rich range of the part was analyzed by measuring its current-voltage characteristics in various gas mixtures. The analysis revealed that the limiting-current characteristics corresponding to combustible gas concentration rely on the oxygen dissociated from H2O.
