Theoretical Concept of Power Drivetrain in Human Powered Vehicle
Frank, Boris ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
Thesis is aimed on regeneration braking systems in human powered vehicle, which uses a flywheel as an energy storage medium. In the beginning is research about design and usage of flywheel energy storage systems in vehicles. Research about possibilities of continuously automatic shifting in HPV is also accomplished. Practical part deals with design of flywheel and FEM analyses of it. Also take into account practical aspects and problems of designing kinetic energy recovery system in bicycle. In energy balance thesis appreciate contribution of practical application of this system.

Bioetanol and Drive of Automobile
Smeták, Pavel ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
Content of my diploma thesis focuses on identification of properties and usability of nascent fuel for automotive use. It is a bio-ethanol which can be produced from renewable sources. The heart of this work is to develop methodology of experimental trials in connection with utilization of bio-ethanol E85 as a fuel for vehicle combustion engines. The aim is to perform tests with E85 and BA95 fuels in engine testing room of ÚADI FSI, to compare these trials amongst themselves and to analyze obtained results. Subsequent part of diploma thesis covers overview of general usage of bio-ethanol in road transportation.

Ideal cycles of combustion engines
Kertész, Tibor ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
The main subject of this bachelor´s thesis is to summarize basic theoretical knowledge of ideal thermodynamic cycles and to develop their mathematical models in Matlab to calculate and draw diagrams of each cycle. Based on the calculated values, it was possible to compare the cycles with each other.
