Dieselgas Engines
Březina, Tomáš ; Böhm, Michael (referee) ; Štětina, Josef (advisor)
This bachelor thesis deals with the topic of Dieselgas engines. The first part work is focused on the history and development of engines and motor fuels. The second part deals with diesel engines, a description of the engine operating cycle, fuel injection system, types of diesel fuel, engine efficiency and emissions. The following chapter provides an overview of gaseous fuels suitable for passenger and public transport. Of these fuels, the two most commonly used are further elaborated. The fourth chapter deals with the use of gaseous fuels in diesel engines, the possibility of conversion of these engines, both by conversion to petrol and without this change. The last chapter deals with the effect on consumption and emissions of dual fuel engines.

Hydrogen fuels
Umlauf, Martin ; Bébar, Ladislav (referee) ; Jícha, Jaroslav (advisor)
Paper presents a basic review and comparison of energy-conservation made of renewable sources. Principal question of paper concerns evaluation of hydrogen-use made of electrolysis of water. First part of the thesis focuses on the production of energy from renewable sources and the possibility of energy-accumulation. The next section describes methods of hydrogen production and utilization of hydrogen as a fuel for combustion engines. Attention is paid to various aspects dealing with construction of combustion engines using hydrogen. Final part of the study presents comparison between combustion engines using known sorts of fuels as to their pollution and emission-level. Next comparison deals with economic cost per kilometer, when different sort of fuels are taken into account. Conclusion concerns approximate calculation of the production of hydrogen from water by electrolysis using photovoltaic power plants.

Possibilities of Present Automobile Fuels Substitution
Doležal, Lukáš ; Svída, David (referee) ; Dundálek, Radim (advisor)
The presented bachelor thesis deals with contemporary fuels and their substitutes . The first part summarises properties and future of crude oil and today commonly and mostly used fuels that are made from oil. These are mainly petrol and diesel oil. The second part is focused on alternative fuels such as LPG, natural gas, bio-fuel and hydrogen. Each subchapter summarises the most important characteristics, advantages and disadvantages. The third part deals with electric energy used as a substitute . This chapter is divided into three subchapters, namely electromobiles, fuel cells and hybrid vehicles. The individual subchapters again summarise the most important information, above all advantages and disadvantages. In the conclusion, emulsive oil is also mentioned.
