[0002] The main function of the oil injection ring in the gas turbine unit is to scrape off the excess oil on the cylinder wall and spread a uniform oil film on the cylinder wall, which can prevent the oil from entering the cylinder and burning, and reduce the wear of the piston, piston ring and cylinder wall. The oil ring is a piston ring, which is divided into ordinary oil ring and combined oil ring. The piston ring is a metal ring used to be embedded in the piston groove. The role of the gap is to cause thermal expansion when it comes into contact with high-temperature gas during the operation of the engine. The periodic reciprocating motion causes it to expand and contract radially. In order to ensure the normal operation of the engine, the piston ring has a gap in the cylinder.
