| Educational objectives | The course represents a strongly experimental-oriented course on energy systems. The main objective of the course is to provide students with advanced skills for the design analysis and functional verification of components and energy systems for sustainable mobility. The main acquired knowledge will include: - Analysis of propulsion systems: innovative internal combustion engines, hybrid and electric powertrains. - Analysis of vehicle-powertrain coupling issues, with particular attention to energy and environmental impact. - Analysis and optimization of powertrain control strategies with vehicle homologation cycle execution. |
| Prerequisites | The topics covered in the module require to have the ability to solve simple mass and energy balances and the ability to solve simple integrals and derivatives. |
| Teaching methods | The course is organized as follows: - Classroom lectures on all course topics. - Lectures in Laboratorio di Macchine. |
| Other information | Nothing |
| Learning verification modality | - oral exam - project/case study |
| Extended program | - Unit 1: Energy analysis of the vehicle: kinetic, potential, aerodynamics, rolling resistance, inertia. Powertrain operating modes: traction, braking, coasting. - Unit 2: Powertrains based on internal combustion engines Historical overview, operating principles. Modeling. Powertrains based on innovative internal combustion engines (ICEs), standard types, comparison with innovative low-impact solutions using non-fossil fuel such as hydrogen, ammonia, methanol, ethanol, ignited by innovative igniters (Plasma Assisted Igniters, PAI – PreChambers). Advantages and disadvantages of different configurations (gasoline, diesel) with various transmission types (manual, automatic, CVT). - Unit 3: Hybrid powertrains based on interaction between internal combustion engines and electric motors Historical overview, operating principles. Power diagrams and flows. Modeling. Energy and environmental impact, necessity in the context of sustainable mobility. Advantages and disadvantages of different configurations: series hybrid, parallel hybrid, complex architectures. - Unit 4: Powertrains based on electric motors Historical overview, operating principles. Power diagrams and flows. Modeling. Energy and environmental impact, necessity in the context of sustainable mobility. Full electric powertrains based on the use of electric motors powered by battery packs or fuel cells. Analysis of power electronics components: DC/AC Converters (Inverters for e-motor), DC/DC Converters for electrical adaptation, AC/DC Converters (battery chargers). |
