Motori a Combustione Interna
Internal Combustion Engines Flavio Caresana
Basic concepts of thermodynamics, fluidynamics and combustion chemistry
KNOWLEDGE AND UNDERSTANDING:
The course enables students to acquire advanced knowledge on the thermo-fluid dynamic processes taking place in volumetric internal combustion engines.
Topics covered in the course will form the basis for an in-depth knowledge of the architecture and the main components of internal combustion engines. In this way, students enrich their knowledge on energy machines
CAPACITY TO APPLY KNOWLEDGE AND UNDERSTANDING:
The student will have the ability to undertake the evaluation of the thermal and energy performance of the components of an engine and will be able to choose the engine selection criteria on the basis of the application field. These capabilities will consist in a series of professional skills, such as: 1. ability to organize the modeling and design of an internal combustion engine; 2. ability to assess the engine performance in a given application 3. ability to properly understand the formation mechanisms of the main pollutants in the exhausts of an engine and choose the methodologies for their removalTRANSVERSAL SKILLS:
Since the performance of the engine depend on mechanical, fluid-dynamical, thermal, and environmental choices the course will contribute to the completion of the basic technical training, with contributions from various cultural areas that contribute to the culture and professional role of an engineer. The in depth knowledge of such a machine will allow students to test their ability in integrating their knowledge and interfacing with specialists of different areas

Development of the examination
LEARNING EVALUATION METHODS
The exam procedure consists in an oral examination. At least three main topics addressed in the course will be discussed during the oral. The starting topic is at student's choice.
LEARNING EVALUATION CRITERIA
The evaluation consists first in verifing the student's knowledge and understanding of the basic functioning of an internal combustion engine. Then the student will be required to demonstrate his in-depth knowledge on the thermo-fluidodynamic processes taking place both in spark ignited and compression ignited engines with particular attention to gas exchange processes, fuel metering, charge motion in the cylinder, combustion, pollutant formation and pollutant control techniques.
LEARNING MEASUREMENT CRITERIA
The student knowledge is graded through the attribution of a final mark out of thirty. The passing score is 18/30, the highest score is 30/30, brilliant students may receive in addition a praise.
FINAL MARK ALLOCATION CRITERIA
The outcome of the evaluation is positive if the student proves to have knowledge of all the basic subjects covered in the course.
The highest score is achieved by demonstrating in-depth knowledge of the course contents.
Praise is given to students who are particularlly brilliant in exposure and/or demonstrat particular mastery of the matters treated in the course, being able to analyze topics not explicitly covered or to treat standard topics in alternative ways.
