Internal combustion engines
5.00 credits
30.0 h + 30.0 h
Students are expected to master the following skills:
                - be able to characterize a thermal cycle;
                - be able to calculate heat exchanges in simple cases;
                - be able to characterize fluid flows in pipe; as they are covered within the courses LMECA1855 and LEMCA2321.
Main themes
Components analysis, thermodynamics and general mechanics, energetic study, basic gauging, calculation of performances and diagnostic principles. Use of fuels and analysis of their combustion in engines: physicochemical, technological, energetic and environmental aspects

At the end of this learning unit, the student is able to :

1 In consideration of the reference table AA of the program "Masters degree in Mechanical Engineering", this course contributes to the development, to the acquisition and to the evaluation of the following experiences of learning:
  • AA1.1, AA1.2, AA1.3
  • AA2.1,  AA2.3, AA2.5
  • AA3.1, AA3.2
  • AA5.3, AA5.4, AA5.6
  • AA6.1, AA6.2, AA6.3
Provide an analytical description of the functioning of internal combustion engines, as well as the principles of the evaluation of their performances and their basic gauging. Develop the capacity to integrate the various branches of mechanics allowing to structure the description of internal combustion engines, to master its conceptual aspects and to model its behaviour.
The course is composed of two parts:
1. Components analysis, thermodynamics and general mechanics:
- main kinematics chain and functional auxiliaries
- thermodynamics cycles, parietal effects, energy fluxes
- breathing: operation modes, suction and supercharging
- frictions, general architecture, main dimensions.
2. Use of fuels:
- combustibility properties and studies of combustion modes
- study of abnormalities and optimisation of combustion laws
- supercharging technology and control of polluting emissions.
The first part of the presentation gives the necessary bases for the calculations carried out during tutorials under the form of exercises or case studies.
The tutorials integrate in parallel the technological aspects of the second part of the course.
Teaching methods
Teaching is based on lectures, exercises and assignments. 
Evaluation methods
The evaluation is based on : 
- an oral examination on the theoretical knowledge acquired with the course supervisors 
- a written examination on a practical implementation of the course's achievements 
The weighting of each part is announced to the students at the beginning of the academic year. The default weighting is 70% / 30%. 
Special circumstances may lead to a change in the nature of the examination. For example, the oral examination may become written, the exercise examination may be cancelled, etc. Students will be notified in due course.
