Nissan has substantially reduced friction between engine parts by developing the first technology in the world to combine a hydrogen-free diamond-like carbon (DLC)*1 coating with special oil.

Energy is lost due to friction that arises between the hundreds of parts that comprise an engine. This ultra-low friction technology uses nanotechnology in order to reduce friction.

Reduces friction by approximately 40% compared to conventional engines, by forming an ultra-low friction film of nanometer*2 level thickness on top of the hydrogen-free DLC coating.

Use of a hydrogen-free DLC coating improves binding with the engine oil and results in the formation of a firm ultra-low friction film when special oil additives are added.
