We adopted the precision cold drawn, honing and polishing to manufacture the precision Slender Shaft (Piston Rod), every technical target is over the national standard.

我公司专业生产精密细长轴(活塞杆)采用精密冷拔、精磨和高精度抛光的先进工艺制造，各项技术指标均符合并超过国家标准。

The rings have joints (they are split) so that they can be expanded and slipped over the piston head and into the recessed grooves cut in the piston.

活塞环有接口（也就是有一缝隙），这样可以使端部扩张并滑入活塞上的凹槽中。

The cycle of operations is spread over four piston strokes. To complete the full cycle it takes two revolutions of the crankshaft.

发动机的一个工作循环分布在活塞的四个行程中，一个完整的工作循环曲轴需要转动两圈。
