| Abstract: | The operating mode setting, data analysis, wave contrast, fault detection of the 3. 4L 6 cylinders electronic controlled engine's 20 minute hot test with load are discussed. Based on structure and operating principle of oxygen sensor, in detail author introduces the application of contrastive analysis method and the common fault of oxygen sensor detected by testing data statistic analysis and time-domain analysis in the hot test. The test results show that the application of contrastive analysis method successfully accomplishes fault detection on oxygen Sensor. |
