DLC Application In Car Engine

  • Cam Shaft

  • Crank Shaft

  • Engine piston Top

  • Oil Piston Rings

  • Valve Lifter

  • Piston Pin

  • Fuel Pump Components


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 the

World .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 .

  • Future Research


Engine Components

Pistons DLC Coating

  • Prevent knocking

  • Prevent Hot spots

    Piston Pin DLC Coating

  • Bearing Bushes

    are not needed

Coating Properties


Future developments and economic consideration

  • Designers within the racing industry see the key driving forces of automotive engine coating development as being one or more of the following.

  • Lower friction

  • Greater reliability

  • Greater load capacity

  • Lower part cost
