Course content

The main objective of the course is to give the students an introduction to reciprocating internal combustion engine with emphasis on marine and stationary applications. The focus is on gaining understanding of the complex processes taking place in an engine with special attention to the detailed examination of a laboratory engine and the diagnostic systems utilized to conduct a detailed test.

The students are actively involved in a mini research project using the lab engine and expected to operate at every stage of a "research project" form designing the research project, performing data collection, evaluating, reporting.

Learning outcome

Learning outcome

The introduction to internal combustion engines is based on explaining processes and performance by application of first principles in:

  • thermodynamics,
  • combustion (chemistry, fuels, emissions),
  • heat transfer
  • fluid flow-gas exchange
  • mechanical dynamics.

This approach provides a basis for analysing and understanding the complex interactions between subsystems and processes inside the engine system.

Upon completing the course, the student should be able to (Learning Outcomes): -

  1. Describe and explain different types of reciprocating internal combustion engines (ICE), Lecture.
  2. Their typical design features and performance characteristics. Lecture and project.
  3. Describe and analyse the power cycle of internal combustion engines using ideal gas cycles, air cycles, and fuel-air cycles. Lecture.
  4. Compute indicated power and thermal efficiency. Project.
  5. Describe and explain the gas exchange process and power boosting by means of turbo charging. Lecture, Project.
  6. Describe and explain engine heat transfer and its relation to thermal loading of engine components and cooling. Lecture.
  7. Compute rate of heat release based on measured dynamic cylinder pressure. Project..
  8. Explain the characteristic of homogeneous combustion in SI-engines and spray combustion in CI-engines. Lecture, Project.
  9. Fuel quality requirements of SI- and CI-engines. Lecture, Project.
  10. Describe the main components of exhaust emissions and explain the mechanisms of emission formation. Project.
  11. Describe methods for reduction of exhaust emissions, and their relations to fuel quality and engine performance. Project.
  12. Describe the kinematics of the crank mechanism and compute inertia forces and moments in single- and multi-cylinder engines. Lecture.
  13. Describe and compute balancing of inertia forces. Lecture.
  14. Define and evaluate dynamic forces in the crank mechanism and compute the angular speed variation of the crank shaft. Lecture.
  15. Describe and explain engine friction, wear and lubrication. Lecture.

Lecture or Project denotes how this outcome will mostly be delivered.

Learning methods and activities

Lectures which should be attended physically.

Project work - mini research project

Compulsory assignments-Obligatory exercises/sessions

  • There will be two lab sessions which are mandatory as this will be when the students learn how to operate the rig, which they will need to do to collect the data for their project. Students must submit notes from lab sessions, detail the rig, draw scheme, detail the parts and measurement techniques used.
  • 5 exercise sessions - must be attended at least 4 out of the 5 followed by submission of exercises. This will be where students need to apply some of the thermodymnics theory and calculations.
  • Experimental design session - this will be a session to develop a hypothesis which can be tested in the lab - such as impact on efficiency or emissions for different fuel or different operations. Experimental matrix will be developed in this time. Students must submit an experimental plan for the project.
  • Computer lab session on use of stochastic reactor model - submission of tutorial model.

Compulsory assignments

  • Completion of 8 assignments

Further on evaluation

Aggregated assessment is the basis for the grade in the course. The assessments include a final oral exam (50%) and project (50%). The results for the parts are given in grade which are used to assign an overall grade.

Oral exam will be given in English only. Postponed/repeated exams will be oral.

Project re-take will be in the form of resubmission of complete project.
