TMR4280 - Internal Combustion Engines
Lessons are not given in the academic year 2020/2021
The main objective of the course is to give the students an introduction to reciprocating internal combustion engines with emphasis on marine and stationary applications.
The focus is on explaining engine performance in terms of power, energy utilization and exhaust emissions, its relation to internal processes like combustion and gas exchange, and varying engine operating conditions.
The introduction to internal combustion engines is based on explaining processes and performance by application of first principles in thermodynamics, chemistry, heat transfer, fluid flow, and 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:
- Describe and explain different types of reciprocating internal combustion engines (ICE), their typical design features and performance characteristics.
- Describe and analyse the power cycle of internal combustion engines using ideal gas cycles, air cycles, and fuel-air cycles. Compute indicated power and thermal efficiency.
- Describe and explain the gas exchange process and power boosting by means of turbo charging.
- Describe and explain engine heat transfer and its relation to thermal loading of engine components and cooling.
- Compute rate of heat release based on measured dynamic cylinder pressure.
- Explain the characteristic of homogeneous combustion in SI-engines and spray combustion in CI-engines. Fuel quality requirements of SI- and CI-engines.
- Describe the main components of exhaust emissions and explain the mechanisms of emission formation.
- Describe methods for reduction of exhaust emissions, and their relations to fuel quality and engine performance.
- Describe the kinematics of the crank mechanism and compute inertia forces and moments in single- and multi-cylinder engines. Describe and compute balancing of inertia forces.
- Define and evaluate dynamic forces in the crank mechanism and compute the angular speed variation of the crank shaft.
- Describe and explain engine friction, wear and lubrication.
Learning methods and activities
Lectures, exercises, project work, and laboratory exercises. The subject is included in the MSc programme for foreign students. Lecturing in English language.
Further on evaluation
Portfolio assessment is the basis for the grade in the course. The portfolio includes a final written exam (70%) and exercises (30%). The results for the parts are given in %-scores, while the entire portfolio is assigned a letter grade.
Examination papers will be given in English only. Students are free to choose Norwegian or English for written assignments.
Postponed/repeated exams may be oral.
For a re-take of an examination, all assessments during the course must be re-taken.
Exam registration requires that class registration is approved in the same semester. Compulsory activities from previous semester may be approved by the department.
