INTERNAL COMBUSTION ENGINES
The course objective is to understand the operation, the control, the architecture and the chemical and physical phenomena that characterize the internal combustion engines. Thus, the course will be devoted to provide the tools needed for performing a critical analysis on the choice of the ICEs according to the application fields. Moreover, great attention will be devoted to the combustion process with the aim to estimate its influence on performance and emissions. Finally the hybrid configuration will be analyzed.
