This document summarizes a presentation about dual clutch transmissions. It begins by explaining how a traditional clutch works and its disadvantages during gear shifts. It then introduces dual clutch transmissions, which use two clutches to engage odd and even gears separately in order to eliminate power losses during shifts. The key advantages of dual clutch transmissions are smooth gear changes without power interruption and improved fuel efficiency. However, they are more expensive to manufacture and require special fluids. In conclusion, dual clutch transmissions provide up to 15% better fuel economy while allowing for faster driving and greater comfort compared to conventional transmissions.

2. Content
 What’s clutch
 Working of clutch
 Why we need new clutch transmission system
 Dual clutch Transmission
 Advantage & Disadvantage of DCT
 Conclusion

3. CLUTCH
A clutch is a mechanical device that
engage and disengage the power
transmission from driver to driven
shaft
Allows smooth engagement of
engine to transmission

4. CLUTCH PARTS
4
• Flywheel
• Clutch plate
• Pressure plate

5. Working of clutch
 When a gear shifting happens…

6. Working of clutch
 First, the clutch is opened.

7. Working of clutch
 Second, driver shifts the gear with the
lever.

8. Working of clutch
 Finally, the clutch is closed.

9. Disadvantage
 Waste of fuel
 Power-lost during the gear shifting
 Discomfort

10. Overview of DCT
 In DCT system two clutches are use
 First clutch is engage with odd gears
 second clutch is engage with even gears
 The gear are controlled hydraulically by a
electronic control unit (ECU) which sense
the gears position and shifting

12. Working of DCT

14. • Power is always transferred to the
wheels

15. Advantages of DCT
 No power interruption at gear shifting
 Very smooth gear-shift operations
 Less fuel consumption
 Better drive and Better comfort
 Drive faster and faster

16. Disadvantages of DCT
 Expensive to manufacture
 Heavier than a conventional manual transmission
 Expensive transmission fluids/lubricants with
additives

17. Who are using DCT ?
 VOLKSWAGEN
 BMW
 PORSCHE

18. CONCLUSION
 Better fuel economy up to 15% improvement than
conventional transmission
 DCT system best for Drive faster as well as comfort
and performance.
