在二冲程发动机中你必须混和燃料和气体，因为气缸壁上的孔阻止使用活塞环密封燃烧室。
You have to mix oil into the gas in a two-stroke engine because the holes in the cylinder wall prevent the use of rings to seal the combustion chamber.
曲径汽封和活塞环提供了双密封系统，使油保持洁净并减少磨损。
Labyrinth seal and piston ring provide a dual sealing system, keeping oil clean and reducing wear.
活塞环没密封(引擎用油)。
Piston rings not sealing (oil being consumed by the engine).
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.
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.
在活塞环的内侧设置金属的弹力环增加非金属活塞环的预弹力，可到达预期的密封效果。
Metal elastic force ring inside piston rings can add initial elastic force of the non-metallic piston ring to get expectative seal effect.
汽车发动机上的活塞环通常是有接口的。但在一些重型发动机上，活塞环的接口可以是斜角接口，搭接式或密封式的。
Rings for automotive engine usually have butt joints, but in some heavy-duty engines, the joints may be angled, lapped, or of the sealed type.
活塞环必须保持自由以便能正确地运动及维持好的密封。在活塞环槽内和活塞岸上的沉积物必须被控制。
Rings must remain free to function properly and to maintain a good seal. Deposit build up in the ring grooves and on piston lands must therefore be controlled.
