| 摘 要： | 利用CFD软件Fluent对CFR发动机进气道进行了三维仿真，在不同的大气压下，对进气系统的气体流场、空气流量和汽油流量进行了定量分析，得出了进气量、进油量和空燃比随外界大气压的变化规律，为辛烷值测试仪的改进提供了依据。

| Abstract: | The intake pipe of CFR engine was simulated three-dimensionally using CFD software Fluent. The airflow field, air flow and gasoline flow in the intak pipe under different atmospheric pressures were analyzed quantitatively. The variation of air intake, gasoline intake and fuel-air ratio in relation with the change of ambient atmospheric pressure was studied, providing reasonable reference for improving the octane number test machine. |
