Fundamental concepts are heavily applied Concordia University Ref: Gill et al. (1959) Engineering masterpiece – design involved many interdisciplinary subjects 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 Concordia University References • Really no required textbook for this course - C.R.

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 Concordia University
