• The piston ring is located on the engine piston and is responsible for sealing the cylinder and controlling the oil circulation.
• Piston rings are usually composed of several separate rings, including compression ring, oil control ring and spare ring.
• The installation of piston ring must ensure the correct direction and position in order to minimize leakage and friction.
• Control the oil flow: The oil control ring in the piston ring is located under the compression ring, and its function is to control the oil flow and lubricate the cylinder wall. It prevents lubricating oil from entering the combustion chamber and lubricates the oil to the correct position to reduce the friction and wear between the piston and the cylinder wall.
• Adjust the clearance between cylinder wall and piston: The clearance between piston ring and cylinder wall is accurately calculated and designed. This clearance has an important influence on the free movement of the piston, the control of lubricating oil and the thermal expansion. Proper clearance can ensure the normal movement of the piston and provide an effective seal."
