| Abstract: | The initial torque and tightening angle of cylinder head bolts for a light-duty high-speed diesel engine were calculated based on VDI2230. During the calculation, the bolt tightening method of VDI2230 was modified based on the experience of a famous engine research institute. The available range of initial torque and tightening angle were gotten while the cylinder head bolts were working on the plastic region, and which could guide the tightening of cylinder head bolts during the engine assembly. |
