Internal Combustion Engines

Recommended Prerequisites

Mathematical Analysis I, Mathematical Analysis II, Mathematical Analysis III, Physics I, Physics II, Thermodynamics, Applied Thermodynamics, Heat Transfer, Heat and Mass Transfer, Fluid Mechanics I, Fluid Mechanics II.

Teaching Methods

The methodology followed in the lectures consists in motivate the student to study the subject to be presented and to present the subject in an understandable way. The presentation of the class is done using audiovisual media.

The methodology followed in theoretical and practical classes consists in solving theoretical and practical problems carefully chosen to allow to reach an interesting conclusion and as general as possible. Conduction of one numerical simulation work of the operating cycle of an ICE. Conduction of one experimental test of an ICE in an engine test bench.

Learning Outcomes

To study from a fundamental perspective the physical and chemical processes occurring in an internal combustion engines (ICE), the types of ICE, its applications, their economic and environmental impact. For that the students must understand its basic working mode, know the geometric concepts and the operating parameters of an ICE, know the thermochemistry of gas mixture, and know the main pollutants emitted by the ICE, the technologies to reduce pollutant emissions and the applicable legislation. To apply the knowledge acquired to: selected an ICE for a given application; to make the preliminary design of an internal combustion engine; to make an experimental test to an ICE in an engine test bench; to model the working cycle of a real ICE starting from an ideal thermodynamic cycle with variable thermodynamic properties, considering heat transfer to the surroundings, finite duration combustion, pressure loss in the intake and exhaust processes and friction between engine components.
