活塞环

Piston rings require an oil film between ring and liner and between ring and piston groove to seal against these high pressures and to prevent blowby.

为了密，塞与连杆之间、塞与或塞槽之间需要一层油膜以承受住这些高压、阻止漏气。

The tribophysics of the cylinder liner—piston rings in an internal combustion engine is a typical tribological system with the reciprocating motion and the impacting motion.

内燃机缸套——塞摩擦副系统是一个集往复、冲击于一体的典型的摩擦学系统。
