Copeland 68.1 piston ring is a metal elastic ring that expands and deforms greatly outwards. It is assembled into an annular groove with its corresponding cross-section. According to the pressure difference of gas or liquid, the reciprocating Copeland 68.1 piston ring is connected to the outer circumference of the ring and the cylinder. A seal is formed between one side, the ring and the annular groove.

Copeland 68.1 piston ring is widely used in various power machinery, such as steam engines, diesel engines, gasoline engines, compressors, hydraulic machines, etc. It is widely used in automobiles, trains, ships, yachts, etc. Generally, Copeland 68.1 piston ring is installed in the ring groove of the piston. It forms a chamber with pistons, cylinder liners, cylinder heads and other components to perform work.

　　 Copeland 68.1 piston ring is the core component of a fuel engine. It seals the gas with the cylinder, piston and cylinder wall. There are two commonly used car engines, diesel and gasoline engines. Due to the different nature of the fuel, their Copeland 68.1 piston ring is also different. The early Copeland 68.1 piston ring was formed by casting. However, with the advancement of technology, the high-power steel Copeland 68.1 piston ring was born. With the continuous improvement of engine functions and environmental requirements, various advanced surface treatments are applied, such as thermal spraying, electroplating, chromium plating, gas nitriding, physical deposition, surface coating, zinc-manganese phosphating, etc.

　　 Copeland 68.1 piston ring functions include sealing, oil adjustment (oil control), heat conduction (heat transfer) and guidance (support). Sealing: It means to seal the gas, prevent the gas in the combustion chamber from leaking into the crankcase, keep the gas leakage to a minimum, improve the thermal efficiency, and the leakage will not only reduce the engine power, but also deteriorate the engine oil. This is the gas ring main mission. Oil adjustment (oil control): scrape off the excess lubricating oil on the cylinder wall and apply a thin film of oil on the cylinder wall to ensure the normal lubrication of the cylinder, piston and Copeland 68.1 piston ring. This is the main task of the oil ring.

　　In modern high-speed engines, pay special attention to the role of Copeland 68.1 piston ring in controlling the oil film. Heat conduction: The heat of the piston is transferred to the cylinder liner through the Copeland 68.1 piston ring, which plays a cooling role. According to reliable data, 70-80% of the heat received by the piston crown in the uncooled piston is transferred to the cylinder wall through the Copeland 68.1 piston ring to cool 30-40% of the rear piston is transferred to the cylinder wall through the Copeland 68.1 piston ring. Support: Copeland 68.1 piston ring keeps the piston in the cylinder, prevents the piston from directly contacting the cylinder wall, ensures smooth movement of the piston, reduces frictional resistance, and prevents the piston from hitting the cylinder. Generally speaking, the piston of a gasoline engine uses two gas rings and one oil The piston of a diesel engine usually uses two gas rings and one oil ring.
