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.

为了密封，在活塞与连杆之间、活塞与或活塞槽之间需要层油膜以承受住这些高压、阻止漏。

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.
