Learning outcomes of the learning unit
This course contributes to the learning outcomes I.2, IV.9 of the MSc in mechanical engineering.
Part 1 Fundamental aspects
Study and modelling of the phenomena leading to the conversion of the chemical energy contained in the fuel into the mechanical energy at the crankshaft outlet 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.
Part 2 Application to propulsion
Knowledge of current developments in powertrain technologies
Prerequisite knowledge and skills
Part 1 Fundamental aspects
Fundamentals in thermodynamics
Part 2 Application to propulsion
Great interest for internal combustion engines
Planned learning activities and teaching methods
Part 1 Fundamental aspects
2 guided exercise sessions are organised.
Plus two laboratory sessions:
- Dismantling and reassembly of an engine
- Description of workshops, engine test bench and chassis dyno (or company)
Part 2 Application to propulsion
TP Lab at the Francorchamps center with the possibility of using a 4-gas analyzer, CNG vehicle, description of the engine bench, OBD and electric vehicles.
Analysis of technological developments related to engine efficiency and introduction of their influence in the CO2 calculation on a driving cycle.
(This is to analyze the effect of an engine improvement and not to develop a driving cycle calculation which is part of the performance course ! )

written exam ( open-ended questions )
Written work / report
Further information:
Any session :
- In-person: written evaluation ( report of TP )
Additional information:
A general understanding is required which will be assessed by the relevance of the choice of the technical improvement chosen, the quality of the analysis carried out and the analysis of the results obtained using the calculation tools made available.

Part 1 Fundamental aspects
A visit of a factory or automotive centre is organised.
Part 2 Application to propulsion
A visit of a factory or automotive centre is organised.
Organisational remarks and main changes to the course
Part 1 Fundamental aspects
The course is given during the 2nd quadrimester on Wednesday afternoon. It begins with the presentation of the general schedule which includes the dates of the 7 lessons, the 2 calculations works and the 3 laboratory sessions.
The first laboratory session will consist of dismantling and reassembling an internal combustion engine available in the laboratory (B49), a second session will be devoted to measuring performance and emissions on the engine bench. During the visit, 3rd lab session, the issue of emissions will be raised again.
Part 2 Application to propulsion
The lecture is given during the second quadrimester
