摘　　要：本文通过试验图表的形式比较分析了两种发动机气缸盖螺栓的拧紧方式对气缸盖压紧力的影响,得出结论最佳的拧紧方式是采用角度拧紧法并将气缸盖螺栓拧紧至其本身的屈服强度。This paper compares and analyzes the influence of the tightening methods of two kinds of the engine cylinder cover bolt on pressing force of the cylinder cover. The conclusion is that the best tightening method is to use angle tightening method and tighten the cylinder head bolt to its yield strength.

关 键 词：气缸盖螺栓 力矩拧紧法 角度拧紧法 屈服强度拧紧法
