Unconventional Design of Internal Combustion Engines
Konečný, Tomáš ; Drápal, Lubomír (referee) ; Svída, David (advisor)
The content of bachelor thesis is to explore the possibility of replacing the traditional arrangement of crankshaft and timing mechanism in combustion engines. The aim of this work is to design the default parameters for the selected engine performance. After designing the default parameters are designed and created CAD models of basic engine components. Subsequently developed a basic overview of alternative concepts of internal combustion engines and elaborated a basic available analysis of the structure. In the conclusion of the thesis is evaluation of the results.
