3 days MOT/BIOMOT-E
- Engineers and technical staff involved in motor fuel quality management in relation to engine technologies.
- This course provides a deeper knowledge on issues raised by the use of the new fuels planned for the near or further future: biofuels, gaseous fuels, synthetic fuels, alternative jet fuels.
- Upon completion of the course, participants will be able to:
- understand the economical and environmental context of biofuels developments,
- describe the processes to obtain such fuels as well as their economic and environmental impact,
- know the main characteristics of these fuels,
- understand their impact on IC engines and turbine operation,
- adapt engines and vehicles adaptations when using these fuels.
- No prerequisites for this course.
