Need help regarding automatic transmission

Click For Summary
SUMMARY

This discussion focuses on automatic transmissions, specifically comparing them to manual transmissions. Key points include the efficiency of manual transmissions, which can reach up to 98% in the 1:1 gear, while continuously variable transmissions (CVTs) do not disclose their efficiencies due to proprietary reasons. The conversation also highlights that manual transmissions do not require water cooling, unlike some CVTs, indicating lower efficiency. Resources for further research include articles from HowStuffWorks and Wikipedia on CVTs.

PREREQUISITES
  • Basic understanding of automotive transmission systems
  • Familiarity with the concept of efficiency in mechanical systems
  • Knowledge of continuously variable transmissions (CVTs)
  • Ability to create presentations using tools like PowerPoint
NEXT STEPS
  • Research the efficiency ratings of various CVT models
  • Explore the differences in design and functionality between automatic and manual transmissions
  • Learn about the latest advancements in CVT technology
  • Investigate the environmental impact of different transmission types
USEFUL FOR

Automotive engineers, students studying mechanical engineering, and anyone interested in understanding the differences between automatic and manual transmission systems.

hiiii...
i needed some help in collecting some articles related to automatic transmission...i need the basic idea of it,and comparison with manual transmission...
 
Engineering news on Phys.org
can i have a basic idea of preparing ppt about automatic transmission...what an all should be included in it
 
The following website has a good discussion of the various types of continuusly variable transmissions (CVTs)
http://en.wikipedia.org/wiki/Continu...e_transmission
None of the CVTs have efficiencies as high as manual transmissions: about 96% in all but the 1:1 gear which is about 98%. Manufactirers of CVTs will not disclose the efficiencies of their designs; it is proprietary.

Note that manual transmissions in standard automobiles do not require water cooling. If a particular CVT requires water cooling, that is proof that it is less efficient than a manual transmission.
