Alternative fuels for internal combustion engines
Žídek, Tomáš ; Maršálek, Ondřej (referee) ; Píštěk, Václav (advisor)
In this bachelor thesis is processed a survey of the alternative fuels for the spark-ignition combustion engines. The properties and the production, the most important components, infrastructure of service station and representatives of the vehicles powered by the type of specific fuel are stated for these fuels. There are defined the benefits and disadvantages of alternative fuels. The properties and parameters are critically evaluated for individual fuel. The use of alternative fuels in the future is outlined at the end of this thesis.

Formula Student Drivetrain Components Design
Kolečář, Tomáš ; Píštěk, Václav (referee) ; Ramík, Pavel (advisor)
This batchelor´s thesis deals with description of formula student drivetrain components. Knowledge acquired in the theoretical part is applied in construction part of thesis. With structural design relates determination of drivetrain loading, stress analysis of driveshafts, stub axles and sprocket´s flange. All components were designed by using finite element method in software Ansys Workbench.

Design concept three wheel small utility vehicle
Ambrož, Petr ; Píštěk, Václav (referee) ; Rasch, František (advisor)
This diploma thesis deals with design concept of three wheel small utility vehicle with curb weight 300kg. At the beginning is short description of some similar vehicles. Analyses of used concepts and descriptions of constructions parts have preceded their choice. Then is created 3D model in PRO Engineer and calculations of driving output and stress analyses are based on it. In design concept is accent putted on ergonomics, look, practical utilization and manufacturability.

Piston group of a one-cylinder gasoline engine
Lux, Josef ; Novotný, Pavel (referee) ; Píštěk, Václav (advisor)
This thesis deals with a piston set of the internal combustion engine. The main goal is to perform strength check analysis of the internal combustion engine piston set using analytical methods of elasticity and strength. Cultivator PF-62 was chosen to determine the basic parameters of the crankshaft mechanism and plot the force distribution. Results of the strength check analysis are evaluated in the final part of this thesis.

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.
