较大提高密封环的密封性可以超越你的动力输出范围从而获得更大的扭力和动力！
Plus, you'll have much better torque and power across the power range from the vastly improved ring seal.
上面装有活塞环，从而使活塞和气缸壁之间具有良好的密封性。
It is equipped with piston rings to provide a good seal between the cylinder wall and piston.
结果表明，磨损对环组的密封性能影响很大，而工况对活塞环的密封性影响不是很明显；
The simulation results show that wear has a great influence on piston tings seal, but the influence of working conditions is not obvious.
