    • An air-fuel ratio in the lean range is detected by measuring a limiting current when oxygen diffused to a first electrode is pumped to a second electrode via a solid electrolyte. A stoichiometric air-fuel ratio is detected from electromotive force between first and third electrodes when oxygen is pumped from the first electrode to the third electrode. The invention is characterized by use of such three electrodes. Furthermore, an air-fuel ratio in a rich range is detected by either sending oxygen from the first electrode to the third electrode via the solid electrolyte and measuring a current when the electromotive force between the first and third electrodes is controlled to be constant, or measuring a current when the air-fuel ratio range is judged as "rich" from this electromotive force and the polarity of the impressed voltage at the time of lean detection is reversed.
    • 当通过固体电解质将扩散到第一电极的氧气泵送到第二电极时,通过测量极限电流来检测贫气范围内的空燃比。 当氧气从第一电极泵送到第三电极时,从第一和第三电极之间的电动势检测到化学计量空燃比。 本发明的特征在于使用这样的三个电极。 此外,通过经由固体电解质从第一电极向第三电极发送氧,并且当第一和第三电极之间的电动势被控制为恒定时,测量电流来检测浓范围内的空燃比,或 当从该电动势判断空燃比范围被判定为“浓”时,测量电流,并且在稀疏检测时的外加电压的极性相反。
