Abstract： This study aims to optimize the sealing structure of the internal combustion engine cylinder head and solve the leakage problem. Taking a leakage fault of the internal combustion engine cylinder sealing structure as a research case， the causes of the leakage problem are analyzed through a multi-dimensional simulation method， including asymmetric lift distribution， uneven contact pressure at the sealing interface， and bolt axial force attenuation. Based on the above causes， a targeted optimization scheme is proposed， and a satisfactory optimization effect is achieved， effectively solving the leakage problem of the cylinder head sealing structure.
