The unit deals with the most relevant topics related to advanced reciprocating Internal Combustion Engines (ICE), alternative fuels for the transport sector, the development of electric powertrain units and the application of fuel cell to mobility systems.
The main objectives of the course are: to provide an adequate and critical knowledge on environmental friendly propulsion systems for different applications, taking into account energy-related and economic issues. To develop skills for the analysis and comparison of advanced systems and technologies for ultra-low emissions Internal Combustion Engines (ICE), the use of alternative fuels (biofuels, NG, hydrogen), the development of hybrid propulsion systems and the application of fuel cells to road vehicles propulsion. To provide criteria for the selection of different systems and technologies referring to several application fields, allowing a first assessment of real benefits in terms of energy consumption and environmental impact for the proposed technical solutions compared to conventional systems.
At the end of the unit, the student is expected to be able to:
Basic thermodynamic knowledge (suggested)
Basic knowledge on Internal Combustion Engines (suggested)
54 hours of lectures, including discussions of technical issues, selection of topics for detailed analysis on available literature, preparation of presentations for seminars in classroom.
Lectures
Advanced systems and technologies for ultra-low emissions ICE – General overview on problems, legislation and possible actions. Advanced fuel injection systems. Advanced combustion processes. Innovative devices and systems for exhaust emissions control. Advanced turbocharging concepts. CO2 emission reduction in thermal engines. Downsizing concept and related technologies.
Alternative fuels – Natural gas. Hydrogen and hydrogen-methane mixtures for thermal engine powertrains. Biofuels. Ammonia and methanol. CO2 emissions overall balance. Well-to-wheel analysis.
Electric and hybrid propulsion – Electric powertrain: advantages/disadvantages, performance, operating range, costs, components, overall energy and emissive balance. Hybrid propulsion: hybrid system configurations, hybrid categories (start-&-stop, micro, mild, full hybrid systems), main features, characteristics and limits of operating configurations, applied examples, overall energy and emissive balance, further developments.
Fuel cell application to propulsion systems – General overview on the electrochemical conversion process, fuel cell types and characteristics. Fuel cell application to powertrain systems: types, operating problems, performance, hydrogen generation and storage systems, energy and emissive balance; applications, technical and economic issues, further developments.
Detailed notes on the different topics discussed in lectures will be provided by the teacher through the Aulaweb page. Therefore, all registered students will access documents to prepare the exam. It is recommended to attend the lectures.

All class schedules are posted on the EasyAcademy portal.
Examination is based on an oral test, proposing two questions, selecting their subject among the unit topics.
For students with specific learning disabilities, more time will be available and the use of concept maps will be allowed, after presenting the relevant certificate.
The following aspects will be evaluated:
