摘要
对国六柴油发动机的缸盖罩内置迷宫式油气分离结构进行模拟分析,对进出口压差和流速、气流速度及分离效率等油气分离性能指标进行了研究。该结构分离效率处于国六柴油发动机油气分离性能的正常范围。
In this paper,the labyrinth oil-gas separation structure in the cylinder head cover of Sixth emission diesel engine is simulated and analyzed,and the performance indexes of oil-gas separation,such as inlet and outlet pressure difference,flow rate,air velocity and separation efficiency,are studied.The separation efficiency of the structure is in the normal range of oil and gas separation performance of diesel engine.
