The course deals with the most relevant topics relating to internal combustion engines for the automotive field, to turbomachines for energy generation and aeronautical propulsion systems and to energy conversion plants.
The course presents operational and functional concepts on internal combustion engines for the automotive field, on aeronautical engines (air propulsion systems) and on energy conversion plants. Moreover, the main numerical and experimental techniques for analysis of machines and energy systems will be presented.
The student attendance during the lessons and related study activities will allow:
- to know the main features related to experimental investigations on internal combustion engines;
- to know the main features related to experimental investigations on turbocharging systems;
- to identify the main features of the turbomachines used in the different application areas;
- to know the architecture of the main types of aeronautical propulsion systems;
- to evaluate the performance of turbomachines;
- to know the basic aspects of emissions and related abatement, renewable source applications, and distributed generation (considering also cogeneration and trigeneration); - to apply the thermodynamic knowledge to the performance calculation of energy systems (also with a software).
It is required that the student has acquired sufficient knowledge of the basic aspects related to fluid machines and energy systems.
Lectures on the different items presented in the course programme and experimental activities on different test rigs, focusing on specific arguments developed within the course. Moreover, seminars offered by academic and industrial experts and technical visits can be organised. Students who have valid certification of physical or learning disabilities on file with the University and who wish to discuss possible accommodations or other circumstances regarding lectures, coursework and exams, should speak both with the instructor and with Professor Federico Scarpa (federico.scarpa@unige.it), the Polytechnic School's disability liaison.
Experimental investigation on reciprocating Internal Combustion Engine (ICE): measuring equipment, test facility set-up, ICE installation on dynamometer test bench, evaluation of engine performance, fuel consumption, ICE pollutant emissions.

Examination: oral test.
Students who have valid certification of physical or learning disabilities on file with the University and who wish to discuss possible accommodations or other circumstances regarding lectures, coursework and exams, should speak both with the instructor and with Professor Federico Scarpa (federico.scarpa@unige.it), the Polytechnic School's disability liaison.
The oral examination will be focused on the topics treated during the lessons and will be aimed at evaluating not only the fulfilment of an adequate knowledge level, but also the acquisition of critical analysis skills on the topics of the exam.
Ask professors for other information not included in the teaching schedule.
