BMW Twelve-cylinder Engines
Macek, Libor ; Janoušek, Michal (referee) ; Drápal, Lubomír (advisor)
Bachelor’s thesis deals with mapping manufacture of BMW twelve-cylinder engines in accordance with current legislation. Thesis described the issue of engine construction and materials with respect to current requirements. Beginning of bachelor’s thesis is dedicated to the history od the BMW brand, especially to founders, first made vehicles and iconic vehicles. Carmaker has celebrated 25 years anniversary of V12 engines in 2012. Third chapter is dedicated to engine marking, because engine marking is difficult to understand. The next chapter is the most comprehensive because it contains a list of engines, including their description and comparison with the competition. In addition to passenger vehicles is thesis briefly focused on sport cars engines and prototypes that were never been mass-produced. The last chapter is devoted to the used technique, primarily to variable valve timing and variable valve lift . Furthermore, it aims to High Precison Injection, Electronic throttle control valves , CAN-Bus and marginally also TwinPower Turbo. In conclusion of the thesis is list of sources, tables and pictures of all engines and pictures explaining used techniques.

Piston and Connecting Rod Assemblies of a SI Engine
Adam, Petr ; Janoušek, Michal (referee) ; Drápal, Lubomír (advisor)
This bachelor's thesis is focused on the design piston and connecting rod set, where was chosen for design the six-cylinder four-stroke spark-ignition engine. In design is going from existing engine, where are designed all parts of piston and connecting rod set on base of it. Subsequently is constructed mathematical model of kinematic and dynamics. Finally is going from dynamic for execution of strength control.

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.
