摘　　要：文章针对某款发动机的两种不同布置方式的油气分离器方案应用STAR CD软件进行模型的压力损失和速度场分析,并进行发动机台架进行曲轴箱压力和油气分离效率的对比分析。分析结果和试验结果同时证明,两种方案的压力损失和速度场相近,分离效果均满足设计要求;但相比较而言,方案二更高的压力损换来了更好的油气分离效果。In view of two plans for oil separator, the analysis of pressure and velocity was studied by STAR CD software, and the research on bench test of engine crankcase pressure and oil separator efficiency was studied in this paper. Though Analysis results and experimental results, The pressure loss and velocity field of the two plan are similar, and meets the design requirements.But plan two have greater pressure loss and better oil gas separation effect.

关 键 词：发动机 油气分离器 压力损失 分离效率
