      Abstract: By means of FEM using ANSYS a three-dimension model was created through Pro/E for S195 diesel engine cylinder block corresponding to real conditions.The distortion and stress of the cylinder block was investigated.The rationality of mechanics model of S195 diesel for stress analysis of engine cylinder block is discussed.The model analysis was made for the cylinder block which provides valuable theoretical base for lightweight and improvement of engine design.
