  3. DLC Application In Car Engine • Cam Shaft • Crank Shaft • Engine piston Top • Oil Piston Rings • Valve Lifter • Piston Pin • Fuel Pump Components

  4. Targets • Reduce energy consumption • Improved fuel efficiency and reduction of CO2 emission • Power Amplification • Better Acceleration • Increase Wear Resistance • Decreasing Friction

  5. Engine ComponentsIncreased Wear Resistance or Decreased Friction

  6. 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

  7. 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

  8. Engine Components Pistons DLC Coating • Prevent knocking • Prevent Hot spots Piston Pin DLC Coating • Bearing Bushes are not needed with DLC Coating

  9. Wear Mechanisms and CoatingsDLC.PNG

  10. Coating Properties

  11. 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

  12. ThankYou !
