The course starts with an in-cylinder pressure analysis for heat release evaluation. Then the engine mechanical design and force transfer from piston to output shaft is analysed. The balancing of multi-cylinder engines is presented. The gas exchange system is presented in some detail. The design of valves and combustion chambers in four stroke engines are discussed. Gas exchange in two stroke engines as well as supersharging are also presented. Carburettors, port fuel injection and direct fuel injection of gasoline the three types of fuel preparation of SI engines, are described with emphasis on direct fuel injection. The third type of internal combustion engine, HCCI, is explained. Finally the Stirling engine is presented in some detail.

At least one laboratory work will be given in which the in-cylinder pressure is measured as a function of crank angle. A course project with contents varying from year to year is also included. It could for example be on heat release calculation from cylinder pressure or gas exchange simulation with commercial software.
