- 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."
