The NNE fault system is mainly controlled by tension-torsional stress, and the NNE-NE fault system by these factors: boundary condition, sedimentary facies zone and regional tensional stress.
In addition, the CAM shaft and the torsional vibration caused by crank will also cause the big change of the chain tension.
此外，凸轮轴和曲轴引起的扭转振动也会导致链条张力的相当大的变化。
