摘要
建立了某小柴油机进气系统的数学模型。使用CFD软件StarCCM对发动机工作情况下进气系统的废气分布以及温度场进行了稳态分析,主要对比分析了有无EGR扩散器两种方案,强调了EGR扩散器对于改善该进气系统的积极影响。
The CFD model for the intake system of one small diesel engine was set up .The exhaust gas mass fraction and temperature distribution was calculated using software StarCCM in engine running conditions .Two proposals were compared as with and without EGR diffuser and the positive improvement of EGR diffuser to the air intake system was put emphasis on .
