Reduce Internal Combustion Engine Fuel Consumption with i-TAC®

Get In Touch

Customer Challenge

When the internal combustion engine is running, piston moves up and down in the cylinder to convert combustion energy to mechanical action. Piston rings seal the combustion chamber and is subject to constant friction during motion. Conventional coating deposited by electroplating cannot meet the friction reduction requirement.

Our Solution

i-TAC® deposits a thick layer of ta-C (tetrahedral amorphous carbon) coating with hardness up to 3,500HV on the piston ring. It reduces the coefficient of friction to less than 0.1, increases airtightness, improves fuel efficiency, reduces carbon emission, extend piston ring lifespan and reduces maintenance needs.
