|
Language(s) of instruction :
|
| English language |
|
Organisation and examination :
|
| Teaching in the first semester, review in January |
|
Course contents :
|
| - Engines classification and applications (propulsion, power production, cogeneration).
- Performance criteria, sizing and influence of atmospheric conditions.
- Gas exchange processes, supercharging and turbocharging.
- Formation, characteristics , vaporisation and combustion of sprays.
- Combustion in Spark-Ignition and Compression-Ignition engines.
- Classical and alternative fuels
- P-theta and P-V diagrams - Heat release rate.
- Pollutant formation and control : NOx, CO, HC et particulates.
- Engine heat transfer and cooling systems. |
|
Learning outcomes of the course :
|
| Study and modelling of the phenomena leading to the conversion of the chemical energy contained in the fuel into the mechanical energy on the shaft of different types of internal combustion engines, in order to get a better understanding for the design (sizing) and/or for an optimal utilization (energy conservation and emissions reduction). Description of the main components of an internal combustion engine. |
|
Prerequisites and co-requisites/ Recommended optional programme components :
|
| Course MECA002-0 "Thermodynamique appliquée et introduction aux machines thermiques"
Course MECA019-0 "Transferts de chaleur" |
|
Planned learning activities and teaching methods :
|
| Practical exercises are solved with the students and some homeworks are suggested. Three training laboratories are proposed ( main components of an internal combustion engine, P-V diagram and heat release rate, heat balance and emissions of a turbocharged diesel engine). A visit of a factory is also organised. |
|
Mode of delivery (face-to-face ; distance-learning) :
|
| The course consists in an oral presentation illustrated by practical examples. It is given during the first semester. |
|
Recommended or required readings :
|
| Extracted from :
- Heywood J.B., Internal Combustion Engine Fundamentals. McGraw-Hill Book Company, New-York (USA), 1988
- Ferguson C.R. and Kirkpatrick A.T., Internal Combustion Engines, 2nd edition. John Wiley & Sons, New-York (USA), 2001

|
Assessment methods and criteria :
|
| A personal home work is asked on a topic chosen in a list. Beside a written report, that work has also to be presented orally. The assessment consists in the personal home work (50%), training laboratories reports (25%) and a written examination in June (25%). |
|
Work placement(s) :
|
| A visit of a factory is organised. |
|
Organizational remarks :
|
| The lecture is given during the second quadrimester (B52 building) and start with an exercise (in the laboratory) which consists in dismounting-mounting an internal combustion engine available in the laboratory (B49). |
