The third oil ring is upgraded with a split design. The split piston ring has multiple advantages.
It can cut friction loss, reduce the frictional force with the cylinder wall via proper contact pressure distribution, enhance mechanical efficiency and save fuel. It can strengthen sealing, adapt to the irregularity of the cylinder wall with its multi-ring structure, stabilize power output and contribute to environmental protection. It can effectively control oil, scrape off excess oil with its special design, reduce oil consumption and carbon deposit risks. It can also boost the durability of piston rings, make the load distribution reasonable among ring pieces, extend the maintenance cycle, cut user's maintenance cost and vehicle maintenance frequency, and ensure the efficient and stable operation of the engine.11 21 7 585 454. 11 21 7 585 460.
