Gas engine piston ring

A gas engine is an internal combustion engine which runs on a gas fuel, such as coal gas, producer gas, biogas, landfill gas or natural gas.

CYPR gas engine piston ring is mainly applying to LPG and CNG engines. The piston ring material includes cast iron (ductile cast iron, high alloy cast iron and alloy cast iron) and steel (stainless steel, carbon steel, alloy steel), the advanced coating, e.g. CCC, CDC, PVD and DLC are widely used. CYPR high performance piston ring has a good wear resistance, high (thermal) scuff resistance, long lifetime and superior fuel economy.
