Learning activities and teaching methods
Monological explanation (lecture, presentation,briefing), Self-study (text study, reading, problematic tasks, practical tasks, experiments, research, written assignments)
Learning outcomes
The course is focused on internal combustion engines and their design. Attention is paid to the construction of the main nodes, both with regard to functional and geometric characteristics, as well as to the use of suitable materials and production processes. Design optimization is supported by computational methods (using suitable models and simulations), but also by verification in laboratory conditions. Learning outcomes of the course unit The aim of the course is to gain knowledge about design solutions and computational procedures used in the development of piston internal combustion engines. Practical experts will also participate in the course, commenting on current trends in engine design.
Students obtain knowledge in given course in accordance with requirements and course programme.
