Objective
Vehicular Internal Combustion engine  What is this course all about?
• not designed as a “nuts and bolts” design tutorial on IC engine or
teach you how to “tune” an engine for racing, etc.
• Reinforce thermo-fluids concepts and apply to engine analysis.
• Introduce students with the basic principles toward designing engines
to satisfy a given power, fuel economy, and emission limit requirement.
Fundamental concepts are heavily applied

How to succeed in this course
• Review your basic engineering subjects
(e.g. thermodynamics, fluid mechanics, heat transfer)
• Study class lectures and update your notebook regularly
• Do the homework (not copy from others)
• Read literature on internal combustion engines and develop an interest in
the subject. Try to write the main points down in your notebook (keep a good
learning record)
• Discuss and collaborate with your colleagues
Most important, ENJOY this course

CALL FOR PROPOSALS
“We make joy”
• As an engineer, we need to have ideas and high quality
proposals on innovative ICE technologies
“Ready for the world, when the world is ready”
Concordia University
Research or Design Project (Graduate)
Students will carry out a research project related to the advanced topic on
Internal Combustion Engines. The purpose of the project is to provide
students with an opportunity to carry out an open-ended research work and to
present it in an acceptable form. The format of the project may consist of the
following:
1. A theoretical study of an engineering problem/challenge related to IC engine.
2. A design and/or development project
3. A survey/assessment of engine development tool or software
4. An ordered and critical exposition of the literature on an appropriate topic in
combustion engineering.
The final submission of the research project should be in the form of a technical
report. Teams must discuss/submit a project proposal (max. 2 pages) by the end
of January 2013
