Targets

Reduce energy consumption Improved fuel efficiency and

reduction of CO2 emission Power Amplification Better Acceleration Increase Wear Resistance Decreasing Friction

Engine ComponentsIncreased Wear Resistance or Decreased Friction

Camshaft DLC Coating

Tetrahedral Amorphous carbon (ta-C) coated has been applied to gasoline engines from autumn 2006 for the first time in theWorld .t

IMPACT WEAR MECHANISM

Though a solution by using the DLC coatings has practically

applied in the industry, nobody knows how the Impact wear mechanisms of the DLC

coating acts in low-load .
