Ultimate engine protection — an energy-saving, low-carbon piston ring.

Diamond-like carbon film for engine durability

Give your engine a new lease of life. CTI's energy-saving piston ring uses advanced diamond-like carbon (DLC) coating technology to deliver ultimate protection. With high hardness, a low friction coefficient and a smooth surface, it protects your engine all round while boosting performance and durability.

Powerful protection under high heat and pressure

The piston ring is in constant contact with the high-pressure gases of combustion, enduring enormous impact loads. This DLC ring not only withstands high-temperature, high-pressure conditions but also lowers the friction coefficient as the piston moves rapidly against the cylinder wall, for smoother running. Its high thermal conductivity and dense, gas-tight structure let heat conduct and dissipate quickly, protecting your engine thoroughly.

Longer engine life, lower fuel consumption

With an excellent low friction coefficient, multiple DLC layers deposited on the ring's curved surface greatly improve lubrication and wear resistance, extending the life of the whole engine. The DLC coating also reduces fuel consumption, making your engine more efficient and eco-friendly — for longer, more economical operation you can rely on.
