    摘要: 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.

    摘要: An air-fuel ratio controlling apparatus for internal combustion engines including an oxygen sensor of hermetic type is disclosed. A pump cell of the oxygen sensor is connected with a power supply through a switch circuit for switching the direction of current flow. A control unit computes a setting of oxygen concentration of a reference gas layer of an exhaust gas sensor in accordance with the operating parameters. By a setting interruption, the control unit switches the switch circuit toward exhausting direction, drives the power supply and applies the exhaust current to the pump cell. The completion of exhaustion is detected, the switch circuit is switched to the suction, and the power supply is driven to apply the suction current to the pump cell. The setting is compared with the integration value of the suction current by a comparator circuit, or the suction current is fixed to control the drive time of the power supply. Alternatively, the current corresponding to the setting is applied for a predetermined time thereby to set the oxygen concentration of the reference gas layer to a setting in accordance with the operating parameters of the engine.
