2 Differential Shaft Exhaust Switch Shaft Transmission Gear Injection Ball Joint Brake Discs Synchroniz or Rings Shifter Forks Lambda Sensor Valve Seats & Springs Piston Rings Connecting Rods Cylinder bores

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 Components Increased 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
