The benefits of ceramic piston rings to the main engine

2022-09-23

 For the marine main engine, the piston ring and the cylinder liner are an important friction pair, and good running-in and operation between them is very important for the main engine. For traditional aluminum-coated piston rings, there is no problem in the era of using high-sulfur oil. After all, the sulfur content in high-sulfur oil helps to lubricate between the piston ring and the cylinder liner. After the use of low-sulfur oil, the oil film on the cylinder liner is not as good as before, although the use of high-base number cylinder lubricating oil cannot completely eliminate this effect. This will lead to accelerated wear of the aluminum-coated piston ring, which will affect the friction pair, increase the wear on the cylinder liner, and shorten the service life. If the base value of the cylinder lubricating oil is not increased during this process, the wear will be accelerated. In this case, the use of cermet piston rings will improve the wear resistance of the piston ring, reduce the friction coefficient, significantly reduce the impact on the operation of the friction pair, and prolong the service life of the piston ring and cylinder liner.
