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.
