1-12121-063-2 Piston Ring Set ISUZU Engine 10PD1

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.

What is a piston ring?

Between the piston and cylinder, the piston ring is a part that is needed for an engine to work efficiently. Piston Rings have 2 main functions.

Piston ring function 1 :Seal for combustion gas

Function is to fully maintain in-cylinder airtightness between the piston and cylinder wall

It works hard to keep a lid on combustion gas leaking into the gap between the piston and cylinder created at the time of an explosion.
If combustion gas leaked, full power could not be realized and fuel consumption would increase, which is detrimental both economically and environmentally.

Function 2: Control lubricating oil (engine oil)

Function to constantly create the minimum required lubricating oil layer to prevent burn

Inside an engine's cylinder, the piston ring is subject to high-temperature combustion gas, and, with the piston, must travel and return many thousands of times a minute, or even more.
To ensure the piston ring and cylinder do not burn, and to prevent excess lubricating oil getting inside the combustion chamber, the cylinder wall lubricating oil layer is controlled at the minimum required.
