1. The flame developing crank angle showed little variation with engine load and speed, while the rapid burning crank angle and total combustion crank angle decreased with the increase of bmep. 火焰发展期随负荷和转速的变化不大，快速燃烧期和总燃烧期随负荷的增加而缩短。
2. The crank shaft turns the piston's up and down motion into circular motion just like a crank on a jack-in-the-box does. 曲轴可以把活塞的上下运动转变为旋转运动，就像小丑盒（打开盒子即跳出一个奇异小人的玩具盒）的曲柄所做的一样。
3. Incontrast with conventional crank balance and phasing crank balance, it may reduce the regulation of crankshaft torque effectively. 结果说明，一、二次谐波消去法比常规曲柄平衡法和定相曲柄平衡法优越。
4. The report is a bend fatigue test result for a new crank shaft research, based on which the safety of the crank shaft using has been fully evaluated. 对新开发的中冷增压发动机曲轴进行了单拐弯曲疲劳试验和综合技术的研究，提出了安全性评估结果。
5. Reducer, crank pin bearing so small and no reverse impact load that reducer tooth broken, crank pin fracture will not happen. 减速机、曲柄销受力小，无反向冲击负荷，减速机打齿、曲柄销折断的故障不会发生。
