在发动机工作过程中,气缸盖会因螺栓、螺母的拧紧力矩不均匀、在高温时拆卸受撞击以及长时间受高温、高压等因素的影响而出现翘曲、拱曲和扭曲等变形。气缸盖变形一旦超出允许的限度,将会引起漏水、窜气、冲坏气缸垫等故障。因此,应重视缸盖变形的检修工作,一旦查出气缸盖变形,应及时进行校正修理。 During the working process of the engine, the cylinder head will be warped, curved and distorted due to the impact of the bolts and nuts with uneven tightening torque, disassembly and impact at high temperature, and high temperature and pressure for a long time. Once the cylinder head deformation beyond the allowable limits, will cause leakage, channeling gas, cylinder head gasket damage and other failures. Therefore, should pay attention to the deformation of the cylinder head maintenance work, once identified cylinder head deformation, correction should be promptly repaired.
