• 7E5786 7E-5786 Piston Ring Excavator Engine Parts Fitting For 211B 214B 320 L 320B 322 LN

• Specification

• Function

1.Sealing: It can create a tight seal between the piston and the cylinder wall, preventing high - temperature and high - pressure combustion gas in the combustion chamber from leaking into the crankcase. This function can minimize gas leakage, improve the thermal efficiency of the engine, and ensure the stability of the internal pressure of the engine, which is of great significance for the normal operation and power output of the engine.

2.Oil Control: The piston ring can scrape off the excessive lubricating oil on the cylinder wall to prevent the oil from entering the combustion chamber and participating in combustion, thus avoiding problems such as increased oil consumption and carbon deposition. At the same time, it can also make a thin oil film evenly distributed on the cylinder wall to ensure the normal lubrication of the cylinder, piston and piston ring, reduce friction and wear, and prolong the service life of components.
