Two-fuel systems of CI engines
Malinský, Marek ; Svída, David (referee) ; Dundálek, Radim (advisor)
The aim of this project is to point out the significance of binary-fuel compression-ignition engines and alternative fuels. It introduces comparison of bio fuels and its influence on the function of the engine, and ecological load. It especially raises bio oil as an alternative fuel for compression-ignition engines. Advantages and disadvantages of bio fuels, most common defects and their consequences, and development trends are also mentioned.

Future Trends for Passenger Car Powertrains
Bureš, David ; Drápal, Lubomír (referee) ; Novotný, Pavel (advisor)
This bachelor thesis analyses existing and potential future propulsion technologies in passenger cars. Propulsion technologies are evaluated based on their efficiency, emissions, and amount of vibration. They are then compared with propulsion technologies in current use. Probability of usage from 2020 to 2040 is predicted for each evaluated technology.

Future Trends for Truck Car Powertrains
Střítežský, David ; Prokop, Aleš (referee) ; Novotný, Pavel (advisor)
Bachelor’s thesis is focused on alternative drivetrains used in trucks. There is evaluation of theirs advantages, disadvantages and probability of future expansion, mostly in Europe. There are also several examples of projects of alternative drivetrains in various stages of realization. In the end there is a reflection about which alternative can replace the traditional combustion engine.

Concept of the aircraft CNG engine
Šmerda, Ondřej ; Beran, Martin (referee) ; Svída, David (advisor)
Master’s thesis deals with comparsion and rating the compressed natural gas as an aircraft piston engine fuel. An information search of conventional fuels and differences of the fuel systems for AVGAS and CNG is included. Next part describes the aircraft and its engine on which is the mathematic model based. After that perfomance and consumption data are calculated for both fuels and the results are then compared. At the end of the thesis, a design of the CNG fuel system with components selection is described.
