为提高汽油机的经济性，利用非稳定管流模拟程序对６１０２汽油发动机进气充量的影响因素进行了计算分析，设计了一种新型进气管。通过提高压缩比及化油器的匹配调整，使该发动机的经济性提高３％以上。该研究对经济型发动机的开发有着重要意义。
In order to improve the economy of gasoline engine, the influencing factors of intake charge of 6102 gasoline engine are calculated and analyzed by using unsteady flow simulation program, and a new type of intake pipe is designed. By improving the compression ratio and carburetor match adjustment, so that the economy of the engine increased by 3%. This research is of great significance to the development of economical engines.
