| Abstract: | To reduce exhaust emissions of carburetor type gasoline engine, one effective measure is air-fuel ratio closed loop control working in three-way catalyst converter. The system adopts PIC MPU and fuzzy control. Based on 15 operations regulated by GB-14761 the system was tested in Santana, Jetta, Xiali, Fukang and Aotuo. The result shows that under steady condition air-fuel ratio is controlled near the theoretical value and the emissions are less than the limited value. The system has a good robustness and the arithmetic is easy to realize. |
