摘　　要：气体发动机对各缸的进气均匀性有着较高的要求,利用Fluent软件分别对4种不同的进气管系统进行了三维仿真计算,得到流场不同位置混合气混合均匀性分布及变化情况,并对流场中不同位置混合气混合均匀性进行分析。为解决气体发动机混合气混合均匀性的问题提供参考依据。In the gas engine, the evenness of mixture of each cylinder has high requirements. Three--dimensional simulation cal- culation is carried on respectively to four inlet pipe systems using Fluent software. The evenness of mixture distribution and change situation in different positions of the flow field are achieved from the calculation, and the evenness of mixture in different positions of flow field was analyzed. The calculation results provide a basis to solve the problems of the evenness of mixture in the gas engine.
