Motori a Combustione Interna
Internal Combustion Engines
Flavio Caresana

Seat Ingegneria
A.A. 2015/2016
Credits 9
Hours 72
Period I
Language ENG

Prerequisites
Basic concepts thermodynamics, fluidynamics and combustion chemistry

Learning outcomes
On completion of the course the student will have acquired the technical knowedge needed to understand the operation of an internal combustion engine (ICE) and of its main components. He will have learnt the fundamentals of the chemical and thermo-fluidynamic processes taking place in an ICE and will be able to appropriately chose the section criteria for a given application.

Program
Brief historical introduction Internal combustion engines classification Engine design and operating parameters Internal combustion engines operating cycles Air inlet and exhaust processes in two- and four-strokes cycle engines Supercharging and turbocharging Ignition plants Fuel metering in spark- and compression-ignited engines Combustion in spark- and compression ignited engines Pollutants formation and control Engines cooling Friction losses and lubrication

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.
