Development of Formula 1 cars
Šopík, Lukáš ; Novotný, Pavel (referee) ; Píštěk, Václav (advisor)
This bachelor´s thesis deals with development of Formula One cars from the begging of the Formula One Worlds Driver´s Championship and describes the first twenty years of this development. This period is characteristic as the replacement of the pre-war cars with engine in front for the cars with engine behind the driver, which is typical for nowadays Formula One. There are description of main construction components and their subgroups, which had been improved by using new materials and technologies.

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.

Design of Car Initiator
Suchý, Jan ; Píštěk, Václav (referee) ; Novotný, Pavel (advisor)
The bachelor thesis is focused on proposal solution of automotive initiator construction and design. The proposal is being carried out with regard to the need to ensure the maximum functionality of the whole element. As for the choice of materials and used technology the costs and procedures commonly used today are not being taken into account. The main objective is to eliminate the shortcomings of current automotive initiators and the proposal of technological procedures in the production of a new component.
