进气歧管对柴油机工作过程的影响分析

摘要

The authors use AVL BOOST software to simulate the engine working process, and analyze the influence of intake pipe length, intake manifold length on the engine intake process pressure wave and inflation efficiency. Fi-nally they put forward the optimization scheme which is validated through test.%运用AVL BOOST软件对发动机的工作过程进行模拟计算，分析进气外接管的长度、进气歧管长度对发动机进气过程压力波及充气效率的影响，最终提出优化方案并在试验中验证。
