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

Prerequisites
Thermodynamics I and II (ENGR 241,MECH 351)
Strong background in:
• Thermodynamics: thorough understanding of different
thermodynamics properties/relationship and laws
of thermodynamics
• Basic fluid dynamics concepts (Mech 361)
• Knowledge of calculus and numerical methods
Concordia University
Course topics
1. Introduction: Early history, engine classification, terminology and
abbreviations, engine components and basic engine
2. Operating characteristics: engine parameters, work, mean effective pressure,
torque and power, air fuel ratio and fuel-air ratio, specific fuel consumption, engine
efficiency, volumetric efficiency
3. Thermochemistry: Review of basic combustion such as stoichiometry, 1st law
analysis, equilibrium, reaction kinetics
4. Engine Cycles: review of ideal cycles, more realistic engine cycle
5. Gas exchange: Intake and exhaust, in cylinder flow, valve design
6. Combustion dynamics: Combustion phenomena in SI and CI engines, engine
knock, combustion chamber design
7. Combustion emission and pollution problems
8. Advanced topics and trends in combustion engine design

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

SCOPE: The future of IC engine and its application
• How will future IC engine look like?
• Will IC engine be replaced by something else?
• Do we reach the limit of innovation?
• What fuel will IC engine use?
• What are the challenge facing the automobile industry?
• Are there any new possible design? What are possible technical
improvement?
Goal: To develop an ICE technology which will be
environmental friendly, efficient and sustainable.

Innovation?
- new innovative ICE concept
- Improved design on the current ICE (intake, exhaust, valves, etc.)
- Supermileage and high efficiency engine
- New fuel (biodiesel, hydrogen, nano-metal)
- Emission reduction and regulation
- Green/hybrid car
- cleaner diesel technology
- new application and the future of ICE usage.
- Education on car energy saving

CALL FOR PROPOSALS
“We make joy”
• As an engineer, we need to have ideas and high quality
proposals on innovative ICE technologies
Concordia University
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
