Piston rings are components directly responsible for engine performance, and have progressed along with engines. Each engine manufacturer's most recent engines require further improvements in fuel efficiency, cleaner exhaust, and longer service life because of environmental concerns. Along with these requirements, further lowering friction and improving wear-resistance are required for piston rings, Developing low tension rings, narrow-width rings, and a combination of high-quality, high-performance piston ring materials with surface treatment are the tendency for now.
Function1.Compression gas sealing
Piston rings maintain gas compression between the piston and the cylinder wall.
Piston rings seal the cylinder so that combustion gas generated at the time of ignition does not leak into the opening between the piston and the cylinder. If combustion gas leaks, the engine cannot output sufficient power, increasing fuel consumption? not good both in terms of economy and the environment.
Function2.Lubricating oil film control
Piston rings usually make necessary minimum lubricating oil film for preventing scuffing.
Since gas ignition is repeated many times, the piston goes up and down inside the engine at a rate of several thousand times per minute. A small amount of oil is poured over the pistons so they move smoothly, with little friction between metal and metal. Piston rings adjust the amount of oil.
Function3.Heat transfer
Piston rings transfer heat from the piston crown to the cylinder.
When gas ignition takes place, the temperature inside a piston reaches approximately 300 C. If heat accumulates inside the piston, the engine may be damaged. For that reason, it is necessary to release the heat build-up. Piston rings help release this heat.
Function4.Support piston in the cylinder
Piston rings prevent the piston from knocking on the cylinder wall.
If the piston inclines inside the cylinder, it may touch inside parts and cause engine failure as well. Piston rings support pistons to allow for smooth up and down motion.
Piston Ring Technology
The Ceramic Penetration
Ceramic material is penetrated into the surface by chemical method and metal-ceramic composite layer comes into being.
Advantages:
1. Efficient Oil & Fuel Consumption--Fuel 3%~8% efficient, engine oil 30%-60% efficient.
2. Extended service life--Running-in between piston ring and liner reduces by 100%~ 300%, engine life is extended dramatically.
3. Better Heat Resistance--Heat conduction rises by 40% under normal temperature, leading to engine temperature reduction by 150~300.
4. Broadened Engine Adaptability--Thanks to ceramic-penetrated rings, engine can adapt to extreme high & low temperature, windy and sandy, low density oxygen working environment.
5. Air Pollution Reduction--Blow-by after piston ring friction is prevented, exhaust will be effectively reduced by 40~60% which is up to environmental protection standards.
