This paper has introduced relevant analysis for crankshaft fracture failure of a diesel engine of Europe 4 by CAE, material, manufacturing process technology, etc. The reason of crankshaft fracture failure is mainly due to the low actual safety factor of the crankshaft. The actual safety factor has greatly increased through improving manufacturing process technology and optimizing the frame of the crankshaft, and enhancing material performance of the crankshaft.
