Range Extender Engines for Electric Cars
Kroupa, Jiří ; Janoušek, Michal (referee) ; Drápal, Lubomír (advisor)
This bachelor thesis is about range extender engines for electric cars with focusing primarily on piston combustion engines. In the first part, reasons for using range extender are indicated and the principle of use in powertrain of electric vehicle is explained. Requirements for a combustion engine working as range extender are stated with their impact on development parameters of this engine. The second part describes manufacturers with their range extenders. Three engines are described in detail with emphasis on development, technical parameters and operating strategy. Another range extenders with their basic parameters are mentioned too. Conclusion refers about benefits of using range extenders and their future development is estimated.

Combi-Cycle with piston engine
Kubik, Martin ; Caha, Tomáš (referee) ; Fiedler, Jan (advisor)
The scope of this diploma thesis of focused on processing and calculation of the technological scheme for combi-cycle power plant with piston engine using heavy fuel oil. There are analyzed demands of piston engine for HFO and design of technological process preparation. This thesis analyzes the suitable locations, service options and alternative solution - heating plant with piston engines. Benefits of each option are assessed in the economic model, assuming power as a source of base load and providing support services. The results are intended to assess feasibility of the investment project.

Design of Energy Systems Using Hydrogen as Fuel
Slováček, Adam ; Kermes, Vít (referee) ; Houdková, Lucie (advisor)
The subject of diploma thesis is to gather knowledge in the production and use of hydrogen. This work is devoted to a comparison of the previously existing processes for producing hydrogen, where the vast majority is filled of fossil fuel. Another section is devoted to new materials for the study based on a number of selected patents and the experiment promising new method for decomposition of water. Based on available data will be carried out energy balance and consequently will be drafted energy system using hydrogen as fuel. In conclusion will be future possibilities evaluated in the field of hydrogen energy.
