| Course abstract | |
| The course provides knowledge of the working principle of compression ignition piston engines and of factors affecting the efficiency of the energy conversion process. Students learn practical skills in calculating thermodynamic parameters and analyzing engine operating cycles. The course also provides knowledge of the types of diesel fuel supply systems, their design features and their basic operational principles. The course provides skills to analyse and eliminate potential causes of deviations of the diesel engine parameters from technical regulations | |

| Requirements for awarding credit points | |
| Course assessment with a grade is formed follows:
•2 homeworks (30%) •8 laboratory works (30%) •3 quizzes (40%) Credit points are assigned if the rate weighted average score is at least grade 4. |
|
| Description of the organization and tasks of students’ independent work | |
| Students must solve three homework tasks independently. Students should prepare themselves for quizzes about lectures. | |
| Criteria for Evaluating Learning Outcomes | |
| The grade is formed as the weighted mean of the results of homework, lab tasks and the quiz. | |
