| Abstract: | 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. |
