The overlapping seal osmosis piston ring is the latest high-tech new generation product of Henan Kaifeng Dongri Piston Ring Manufacturing Co., Ltd. This product has obtained national patents and is exclusively owned. This patented product is jointly produced by domestic piston ring enterprises by Japanese advanced technology, and is sealed at the mouth of the gas ring.
The first gas ring is close to the combustion chamber, the temperature is high, the working environment is bad, and the internal power is reduced. In view of the above shortcomings, the patented product overlaps and seals the mouth of the gas ring, and the first gas ring, the oil ring and the scraper are subjected to nitriding treatment; the laser and plasma cylinder sleeves are optimally matched, and the piston ring is sealed at the mouth. The utility model has the automatic compensation function, effectively improves the power, better compensates for the gap enlargement phenomenon, and makes the piston ring always in a gapless state, solves the air leakage phenomenon after the piston ring is worn, effectively solves the exhaust gas emission and reduces the air. Pollution, in line with environmental requirements.
After nearly one year of installation test, the new product has obvious fuel-saving effect, saving 3%-8% of fuel and saving 30%-60% of engine oil. Cylinder liner, piston ring, wear amount reduced by 1-3 times, greatly improving the service life of the engine, heat conduction increased by 40% at normal temperature, and increased with temperature, while high temperature and low temperature, sand and other functions, engine temperature After dropping 150°C-350°C, the exhaust emission is reduced by 40%-60%. Since the birth of the overlapping sealing and seeping piston ring, it has been well received by users all over the world.
Henan Dongri Company adopts the technology of seepage in the piston ring production process, and the “enhanced overlapping sealing and infiltration ceramic piston ring†further improves the quality of the product and forms a new generation piston ring. It has obtained the national patent on February 23, 2001 ( Patent No.: ZL012070254). At present, the project patent has been protected by patent property rights internationally. main feature:
1. The friction coefficient is small, and the service life is doubled compared with the traditional piston ring.
2, reduce vehicle losses, save fuel and lubricants.
3. Reduce waste emissions and improve engine power.
4. The engine temperature is widened, and its excellent comprehensive performance is especially significant for high temperature, low temperature, sand, and oxygen deficiency.
In the past two years, the “enhanced overlapping sealing and infiltration ceramic piston ring†has developed 16 basic varieties, forming a primary scale of 13,000 sets.
