The nose bridge between the inlet valve and exhaust valve is the most fragile part on the cylinder head. Fatigue crack is the major failure mode. It is necessary to analyze the structure strength and reliability (SSR) of this zone. In this paper, a three-dimensional (3D) model for a engine cylinder head is built up using Pro/Engineer wildfire 2.0, and the 3D FEM analysis of the SSR is carried out. The temperature field and stress field of the nose bridge are also calculated based on the model. Several improvement designs are given and compared as the result of the above analysis, which lays the foundation for the cylinder head production.
