• The combination of gas ring and oil ring with high precision machining can make the sealing pressure evenly distributed, which can control the air leakage of the cylinder within 0.5%, ensure the full combustion and improve the engine power.
• The oil scraper angle of oil ring is optimized by hydrodynamics, and the oil scraper efficiency is improved by 30%, which can effectively reduce the oil channeling, reduce the oil consumption and avoid the phenomenon of oil burning.
• It can maintain stable elasticity and sealability in the high temperature environment of 250℃, adapt to high temperature working conditions such as turbocharged engines, and will not lead to seal failure due to thermal deformation.
• Compared with the traditional piston ring, it reduces the friction loss by 20% and improves the fuel economy of the engine.
• The surface of the new ring is specially honed, and the running-in period is shortened to 500 kilometers, avoiding the problems of power loss and excessive oil consumption during the running-in period.
