S1301-92080 Piston Ring Set HINO Engine J08E

A Piston Ring is a metallic split ring that is attached to the outer diameter of a piston in an internal combustion engine or steam engine.

The main functions of piston rings in engines are:

1.Sealing the combustion chamber so that there is minimal loss of gases to the crank case.
2.Improving heat transfer from the piston to the cylinder wall.
3.Maintaining the proper quantity of the oil between the piston and the cylinder wall
4.Regulating engine oil consumption by scraping oil from the cylinder walls back to the sump.

Advantages

1.The surface of piston ring has oxide film, with corrosion resistance, anti-wearlubrication and good appearance.
2.Chrome plated layer, good wear resistance and storage lubricating oil
3.Nitriding treatment, with good wear resistance and corrosion resistance
4.Spring ptfe process, friction coefficient is very low, excellent lubricity.

1.Air tightness

The first function of the piston ring is to maintain a seal between the piston and the cylinder wall to control leakage to a minimum.This effect is mainly borne by the gas ring,that is,the engine is controlled to minimize the leakage of compressed air and gas under any operating conditions to improve the thermal efficiency:to prevent the cylinder and the piston or the cylinder and the ring from being caused by the air leakage.Killing:preventing malfunction caused by deterioration of lubricating oil,and the like.

2.Oil control

The second function of the Piston Ring Set is to properly scrape off the oil adhering to the cylinder wall and maintain normal fuel consumption.When the supplied lubricating oil is excessive,it will be sucked into the combustion chamber to increase the fuel consumption,and the carbon deposit generated by the combustion has a very bad influence on the engine performance.
