摘要
在某型柴油机上将原顶置缸套改为中置缸套结构,以改善第1道活塞环的冷却和减少缸套穴蚀问题。进行了缸套变形有限元计算、冷却系统CFD分析,以及缸套实际变形的测量验证,从而适应该型柴油机的功率、排放和耐久性升级的需求。
In order to improve engine power, emission and durability, change top stop liner to mid stop liner structure for improving the first compression ring cooling and reducing liner cavitation risk. And did the simulation analysis of liner distortion, engine CFD, the liner actual distortion measurement to validate the new design.
