The course aims to provide the students with the skills needed to analyse the operating conditions of internal combustion engines and turbogas for performance optimization in terms of torque, power, consumption and pollutant emissions.
The course aims also to provide the students with refinement of knowledge related to thermofluid dynamics, combustion, formation and control of pollutants, and management of the complete engine system

Modalità Erogazione
Teaching is organized with lectures. Some lessons are dedicated to practical insights of what learned during the theoretical lessons, through exercises guided by the teacher.Modalità Valutazione
The verification of the learning takes place through an oral test in which questions are proposed in order to verify the understanding of the concepts and the ability of the student to apply them in real contexts.
