    • A system for feedback control of air/fuel ratio in an internal combustion engine, utilizing an oxygen-sensitive air/fuel ratio detector disposed in an exhaust gas to provide a feedback signal is disclosed. The detector has a flat and microscopically porous solid electrolyte layer with a measurement electrode layer on one side and a reference electrode layer on the other side facing a substrate. The control system includes a current supplying circuit to force a DC current to flow in the solid electrolyte layer between the two electrode layers to cause migration of oxygen ions through the solid electrolyte layer from the measurement electrode toward the reference electrode to thereby establish a reference oxygen partial pressure at the interface between the reference electrode layer and the solid electrolyte layer. To preclude an undesirably great rise of this reference oxygen partial pressure in the case of a large increase in the amount of oxygen in the exhaust gas resulting from interruption, or great reduction, of the feed of fuel to the operating engine, the control system comprises sensor means to detect the existence of such a condition and means for temporarily decreasing the intensity of the current being supplied to the air/fuel ratio detector.
    • 公开了一种用于内燃机中的空燃比的反馈控制的系统,利用设置在废气中的氧敏感空气/燃料比检测器来提供反馈信号。 检测器具有平坦且微孔的固体电解质层,其一侧具有测量电极层,另一侧的参考电极层面向衬底。 控制系统包括电流供应电路,以迫使DC电流在两个电极层之间的固体电解质层中流动,以使氧离子从测量电极向参比电极迁移穿过固体电解质层,从而建立参考氧 在参考电极层和固体电解质层之间的界面处的分压。 为了防止由于中断引起的排气中的氧量的大量增加或者大量减少对运行发动机的燃料供给而引起的该参考氧分压的不期望的大的上升,控制系统包括 用于检测这种状态的存在的传感器装置和用于暂时降低供给到空气/燃料比检测器的电流的强度的装置。

    • A system for feedback control of air/fuel ratio in an IC engine, utilizing an oxygen-sensitive device which is provided with a heater and disposed in exhaust gas to provide a feedback signal. This device has a porous solid electrolyte layer with an outer electrode layer on one side and an inner electrode on the other side facing a substrate. There is a circuit to supply a heating current to the heater and also force a DC current to flow in the solid electrolyte layer to cause migration of oxygen ions therethrough toward the inner electrode to thereby establish a reference oxygen partial pressure on the inner side of the solid electrolyte layer. This circuit is provided with current intensity regulation means to temporarily decrease the intensity of the current flowing in the solid electrolyte layer by a predetermined value while the oxygen-sensitive device is not sufficiently heated to thereby preclude undesirable rise of the basic level of the output voltage of the oxygen-sensitive device by the effect of an increased internal resistance of the not sufficiently heated element.
