Hybrid vehicle propulsion
Sommer, Matěj ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
This thesis sums up a comprehensive overview of all possible ways of hybrid propulsion and points out the andvatages and disadvantages of each of these designs with special attention to fuel cell vehicles. It includes a presentation of my own opinions regarding this issue and an estimation of future development of hybrid propulsion technologies and their place on the market with personal vehicles.

MEB modular platform for electric cars
Tkach, Svitlana ; Kaplan, Zdeněk (referee) ; Píštěk, Václav (advisor)
This bachelor’s thesis focuses on the possibilities of the newly developed modular electric drive matrix MEB of the Volkswagen Group. The aim was to create a research study about technical parameters of the platform and the possibilities of its use for various categories of vehicles not only within the Volkswagen Group, but also the offer to competing manufacturers. In conclusion of the bachelor’s thesis is formulated the impact of technologies, offered by the modular electric drive matrix, on the development and production of electric vehicles and the related possibility of a reversal in the expansion of electric drive.

Modification of a four cylinder diesel engine to a single cylinder test engine
Mátyás, Attila ; Kaplan, Zdeněk (referee) ; Píštěk, Václav (advisor)
This thesis deals with modification of an existing four-cylinder diesel engine to a singlecylinder research engine. The work is divided into four main parts. The first part is theoretical, briefly describes research engines, their individual types and provides an overview of their functions. The second part of the work includes the modification of a four-cylinder diesel engine to a single-cylinder research engine, focusing mainly on balancing inertia forces. The third, most extensive chapter contains the structural analysis of the crankshaft. The last part contains the design of a torsional coupling, which ensures the connection of the engine with the dynamometer.

HPV
Šmak, Petr ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
Design of frame of a human powered vehicle (HPV) is the aim of this diploma thesis. Wide analysis precedes design process. The thesis describes historical developement of land transportation, especially history of cycling, bicycles and other human povered vehicles, which are not so extended. Preferences and deficiencies of transportation by these ecological vehicles are shown. The thesis includes summary of most widespread and best-known conceptions, including their advantages and disadvanteges. Conception of three-wheeled vehicle was selected. It has two steered front wheels and one powered rear wheel. The accent is putted on wide efficiency, ergonomics, simplicity of vehicle`s frame and possibility of using common cycling components. 3D model of frame and assembly of vehicle was created. This model was checked by FEM computation.

Rotordynamics of Modern Turbocharger
Fryščok, Tomáš ; Dundálek, Radim (referee) ; Kaplan, Zdeněk (referee) ; Píštěk, Václav (advisor)
This dissertation thesis consists rotordynamics of modern turbocharger. First part begins with prediction of critical speed, prediction of onset instability of oil whirl and oil whip by XLTRC2 and comparison with measured data (Cascade diagram, shaft motion, FFT analysis). List of measurement method for the detection of the natural frequency of turbocharger (EMA). Create software for long term monitoring and recording and output data size reduction. Detection of critical speed by defined measurement methodology without using software simulation with measured data from the Cascade diagram, move the rotor shaft motion in the bearing, FFT analysis and results from measurements of natural frequencies. Comparison of predicted data (critical speed, prediction of onset instability) program XLTRC2 with the values measured by this approach measurement (waterfall diagram, shaft motion, FFT analysis)
