30 days MOT/CTRLM-E
- Engineers and technical staff from automotive industry who want to improve their knowledge of powertrain electronic management.
- This course provides engineers with a deeper knowledge on the engine operating physics and the engine electronic control in order to take part in the development of control and calibration strategies on a Dyno test bench and on a vehicle.
- Upon completion of the course, participants will be able to:
- know the parameters used to characterize and control performances, efficiency, combustion, emissions,
- know the combustion mechanisms and how the exhaust gas after-treatment systems work,
- know the architecture and the functions of the engine control systems, the sensors and the actuators,
- have some basic practical knowledge on applied automatics to engine control,
- describe the advantages and the make-up of a torque structure,
- tune up the control strategies of gasoline and Diesel engines, possibly associated to an automatic transmission,
- to implement of the diagnostic functions, both from regulatory and operating safety standpoints,
- know how to build a control law,
- do the tuning and calibration process on an engine.
- No prerequisites for this course.
