| Abstract: | The vehicle self diagnosis technology is an important means of engine fault diagnosis, however for mechanical fault of engine and electrical failure no fault code in the diagnostic, self diagnosis technology is incapable of action. Provides an effective way for exhaust gas detection and analysis technology for the diagnosis of difficult faults of various engine. This paper mainly introduces the keys of fault diagnosis of engine based on the exhaust gas detection and analysis technology, test of diagnosis and study of diagnosis rules, application of diagnosis rules, aims to improve the effectiveness of the engine fault diagnosis. |
