Abstract：In order to reduce the exhaust emissions of gasoline vehicles in the process of emission testing, an exhaust purification system applied to gasoline vehicle emission testing institutions is designed. The mechanical structure and exhaust gas purification posttreatment system are designed based on the function of the exhaust gas purification system, the hardware circuit is designed based on the XE164FN singlechip microcomputer chip, the program is designed and debugged by Keil software, and the purification effect of the exhaust gas purification system is tested and verified. The results show that the exhaust gas purification system has a good purification effect, and the purification efficiencies of CO, HC and NO_x exceed 83%. The purifying device can effectively reduce the pollutant emission of gasoline vehicles in the detection process and protect the environment.
