Automotive Drive Train

3 days
This course is not scheduled.
Who should attend?


    • Engineers and technical staff working in the field of IC engines and wishing to know the role of automotive transmissions and their impact on powertrain operation.


  • Foundation
  • This course provides a better understanding of drivetrains to deal with engine/vehicle adaptation topics, the restrictions found on both engine/drivetrain units and the topics on the powertrain development.
Learning Objectives
  • Upon completion of the course, participants will be able to:
  • know the main types of transmission,
  • understand powertrain matching,
  • describe and manage interactions between engine and transmission,
  • carry out an engine project with the perspective of developing a whole powertrain.
