Product Characteristics
Basis Information
Oil ring: controls the lubricating oil around the piston to prevent oil film from entering the combustion chamber, while scraping excess lubricating oil back into the oil pan to maintain an appropriate amount of lubrication.
Product Process
The material selection of piston rings is very important. Common piston ring materials include cast iron, chromium molybdenum alloy, etc. These materials have excellent wear resistance, high temperature resistance, and corrosion resistance, and can adapt to the working environment of high temperature, high pressure, and high-speed operation of internal combustion engines.
The piston ring is generally composed of several rings, closely connected on both sides. Common structures include oil rings, oil control rings, and upper and lower spiral grooves. The piston rings with different structures undertake different functions, such as sealing the cylinder, conducting heat, lubricating, etc.
