Spark ignition engine with variable compression ratio
Fűri, Peter ; Píštěk, Václav (referee) ; Kaplan, Zdeněk (advisor)
With the aim of reducing pollutant emissions from internal combustion engines, the application of stoichiometrically operated spark ignition engines, for light vehicles, has been overcoming the compression ignition engines market share throughout the past years. The ability of a substantial reduction of the primary harmful emissions (HC, CO, and NOx). Nonetheless, with increasing attention to CO2 emissions, the development of highly efficient downsized spark ignition engines turns to be of enormous interest. However, to enable high load operation on such downsized engines, the compression ratio must be reduced due to knock limitations, reducing the partial-load operations efficiency. The work tries to describe solutions that have already been developed by various car manufacturers and to describe in detail my proposed design solution for changing the compression ratio using two-stage system.

Ignition engine emissions
Semela, Lukáš ; Píštěk, Václav (referee) ; Kaplan, Zdeněk (advisor)
This thesis deals with emissions of ignition engines. The introduction acquaints the reader with the history and lays out the reasons why it is a crucial topic to be dealt with. Furthermore, the term emission is being explained as well as the description of its chemical composition, the impact on the environment and human organism. The method of measuring is also mentioned in this thesis. Then the explanation continues with European Union’s current legislation. The whole thesis is concluded with information on the additional modification of emissions and chapter that outlines the future of automobiles regarding the environment.

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.
