Stable control of oil: Through the oil scraping edge structure, the excess oil on the cylinder wall can be scraped back to the oil bottom shell. At the same time, it avoids the oil from entering the combustion chamber to participate in combustion, and effectively prevents carbon accumulation and excessive oil consumption.
Auxiliary heat dissipation: Part of the heat generated by combustion at the top of the piston can be transferred to the cylinder block through contact with the cylinder wall, and then taken away by the cooling system to help the piston maintain a reasonable working temperature and extend the service life.
Improve wear resistance and temperature resistance: Made of high-quality alloy materials, with excellent high-temperature resistance and wear resistance, it can adapt to the complex working conditions inside the engine and reduce the risk of failure caused by daily wear.
High-efficiency sealed gas: It can closely fit the cylinder wall and the piston, prevent the leakage of high-temperature and high-pressure gas into the crankcase in the combustion chamber to the greatest extent, ensure the efficiency of engine power output, reduce energy loss, and greatly reduce fuel consumption by more than 40%.
