| Abstract: | The study of this paper is based ona top-hung wet cylinder liner diesel engine. In order to improve coolingeffect of the cylinder liner, especially the top part, optimization of the waterjacket is made by improving the support structure of top-hung lin- er. The water flow field of waterjacket, temperature field and thermal deformation of cylinder liner are analyzed by CAE method. The results show that the optimal design can improve the cooling effect of cylinder liner and piston, and thermal deformation of cylinder liner is stable. |
