摘要
电控发动机加装的三效催化转化器要达到最佳的排气净化性能，需要利用氧传感器提供的反馈信号，将混合气的空燃比保持在理论空燃比附近。阐述了氧传感器的工作原理及其故障自诊断，指出了满足 ＯＢＤ Ⅱ法规将是发展方向。
It needs to utilize the feed back signal provided by the oxygen sensor in a triple action catalystic converter to keep the fuel air ratio near the theoretic value so as to reach to an optimum cleaning state of exhaust emission for an electronically controlled engine which the converter is .mounted on. The paper describes how the oxygen sensor realizes the above said working function and its trouble self diagnosis process and points out that future prospective direction shall meet the OBD II regulation.
