Car transportation industry and service industry and automobile manufacturing industry in the national economy construction plays a crucial role, car ownership growth led directly to a large amount of fuel consumption, and thus produced a large number of harmful automobile exhaust gas. Especially in some large and medium cities, the environmental pollution caused by automobile exhaust has become more and more serious. At present, this is a worldwide problem. So the detection and analysis of exhaust emission of automobile engine and the method to prevent the situation has reached the point of no delay. The exhaust of gasoline engine emissions were detected and analyzed to further understand the formation process, detection method and detection object: CO, hydrocarbons, carbon and oxygen compounds, smoke and dust particles, sensors and active carbon tube detection and analysis. Finally, the detection and analysis of gasoline engine exhaust emissions. Key words: gasoline engine tail gas, detection and analysis object, detection method 目录 摘要……………………………………………………………………………………2 目录……………………………………………………………………………………4 绪论……………………………………
