Oil ring for internal combustion engine and piston assembly comprising the same

摘要

The present invention relates to an oil ring for an internal combustion engine and a piston assembly including the same, wherein the oil ring for an internal combustion engine of the present invention protrudes from an upper portion of a body and is in close contact with the inner wall of a cylinder, thereby effectively limiting the explosive gas generated in the combustion chamber. , It is possible to collect and discharge excess oil to the inner wall of the cylinder in the space formed by the scraper part and the compression part and the scraper part, including a nose that protrudes from the lower part of the body and in close contact with the inner wall of the cylinder and scrapes off excess oil. It includes an oil suction unit capable of reducing the leakage of high-temperature and high-pressure gas generated in the combustion chamber, and has an effect of preventing incomplete combustion due to oil leaking into the combustion chamber.
