Course Objectives

This course provides senior undergraduate and graduate mechanical engineering students with a working knowledge of the functional principles, subsystems, and physical components associated with internal combustion engines used in a wide range of applications (automotive, marine, stationery power generation, low-power utility equipment, etc.). Two-stroke and four-stroke, spark-ignited and compression-ignited engines are covered. Students learn to design the subsystems and components of such engines for use in stand-alone applications, and as part of hybrid powertrains. Design projects are emphasized, and CAE software packages are used extensively as design tools.


  1. Introduction to internal combustion engines: classification, operating principles, system identification (5 50 minute classes)
  2. Power train design: pressure, friction, and inertia forces. Balancing schemes, vibration control, mounting systems (4 classes)
  3. Power train component design: crankshafts, connecting rods, pistons, cylinders, frames, bearings (5 classes)
  4. Valve train design: operational and performance considerations (1 classes)
  5. Valve train design: dynamic considerations, cam profile optimization, valve train component design (6 classes)
  6. Mechanical and turbo supercharging. Acoustic tuning of induction and exhaust systems (3 classes)
  7. Engine characteristics, similitude (2 classes)
  8. Effects of engine architecture and component configurations on fuel requirements. Fuel characterization, knock due to auto-ignition or ignition delay, exhaust emissions (5 classes)
  9. Fuel metering systems (4 classes)
  10. Ignition systems (4 classes)
  11. Cooling systems (3 classes)
  12. Special design requirements for compression ignition engines.
  13. Design projects (2 classes)
  14. Tests and final examination (2 classes and 2.5 hrs.)

Computer Use

MATLAB is used for eigenproblem solutions associated with torsional crankshaft vibration, valve train response, and engine mount optimization. Proprietary engine simulation software (DYnoSim) is used for conducting engine optimization studies. Solid modeling and finite element packages are used for component detail design.

Class/Laboratory Schedule

Three 50 minute sessions per week devoted to lecture, discussion, and design/analysis problem solving.


Weekly homework assignments: 15%, midterm examinations (2): 30%, design projects (2): 40%, final exam: 15%. Graduate students are required to perform a special assignment on complex domain eigensolution for damped valvetrain vibration.

Professional Component Contribution

Engineering design: 2 credits, engineering science, 1 credit.

Relationship to Program Objectives

This course supports Mechanical Engineering B.Sc. and M.Eng. program objectives by developing:
