本发明属于机器制造,亦即发动机制造,更具体地说,属于柴油机气缸盖结构的发明。 众所周知的内燃机气缸盖,主要是带有冷却水腔的柴油机缸盖,包括带有顶面与底面的缸盖体分隔成每缸一段的气缸盖,顶面与底面通过相互倾斜的侧壁连接,有固定缸盖和缸体的紧固螺柱及缝合螺柱的孔,缸盖与缸体的气缝处布置有密封垫。 缝合螺栓的拧紧力不是通过气缸中心,而是通过底板减薄部分传递到密封垫上,拧紧力的压力锥不重合紧固螺栓的拧紧压力锥,并作用在30～35％的密封表面。在双头螺栓拧紧时,燃烧室底部及底板减薄部分的刚度小,以致底板的变形相当大,使气缝密封圈边的单位
The invention resides in the manufacture of machines, that is, the manufacture of engines, and more specifically the invention pertaining to the structure of a cylinder head of a diesel engine. The well-known cylinder head of an internal combustion engine, mainly a diesel engine cylinder head with a cooling water chamber, comprises a cylinder head with cylinder heads with a top surface and a bottom surface, which are separated into cylinder sections of each cylinder, the top surface and the bottom surface are connected by mutually inclined side walls, There are fixed cylinder head and cylinder fastening studs and suture stud holes, cylinder head and cylinder air gap at the gas seal is arranged. Sewing bolt tightening force is not through the cylinder center, but through the bottom of the thinning part of the transfer to the gasket, the tightening pressure of the pressure cone does not overlap the fastening screw tightening pressure cone, and the role of 30 ~ 35% of the sealing surface. When the stud bolt is tightened, the rigidity of the bottom part of the combustion chamber and the thinned part of the soleplate is small, so that the deformation of the soleplate is quite large so that the unit of the gas seal seal ring
