摘　　要：对汽油发动机而言,进气管内气体的压力波动会影响下一循环气缸的进气量,而压力波动对气缸进气量的影响程度和进气管的长度、管径、谐振腔容积、发动机转速等因素有关。利用AVL BOOST软件建立了某发动机的工作过程仿真模型,通过改变进气管的结构参数,利用进气谐振来改善进气系统的压力波动,对发动机工作过程进行了数值模拟计算。根据计算结果的分析与对比,得到了最佳的进气系统参数,实现了进气系统的优化设计。For gasoline engine, the next cycle of the cylinder intake air would be affected by the gas pressure fluctuation in intake pipe, in which the degree of influence is related with intake pipe length, pipe diameter, cavity volume, engine speed, etc. A engine work process model is established by using AVL Boost software in this paper, intake system pressure fluctuation is improved by changing the structural parameters of the inlet pipe. Then engine working process is calculated. According to the analysis and comparison of calculation results, the optimal air intake system parameters are obtained and the optimization design of air intake system is achieved.
