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.

Possible Applications of LNG in the Czech Republic
Machalová, Markéta ; Sedláček, Jiří (advisor) ; Kysilka, Hugo (referee)
This thesis evaluates the possibilities of application of LNG (liquefied natural gas) in the Czech Republic. LNG is a relatively new commodity, which has broad use in the world, but as of now, the Czech Republic hasn't entered its market. The main objective of this thesis is to determine whether there exists suitable use for LNG in the Czech Republic today. By analysis and calculation I came to the conclusion, that there are applications that would be economically advantageous and would, in addition, bring other significant benefits, such as reducing emissions. The most perspective is the use of LNG as an alternative truck fuel. Under certain conditions suitable applications are also LNG satellite stations, cogeneration or bus transport. The conclusion of this thesis is that liquefied natural gas has a great potential to expand to the Czech Republic.

Decarbonization and Common Transport Policy the EU
Volková, Anna ; Bič, Josef (advisor) ; Vošta, Milan (referee)
The target of this diploma theses is to evaluate the Common Transport Policy of the EU and the development of decarbonization in world and European economies. The first chapter focuses on the role of transport in economy, common transport policy of the EU and its environmental aspects. Next chapter is specialized in adoption of the Kyoto protocol, than in the global and European development and decarbonization in transportation. Last third chapter aims on the future of decarbonization and the alternative fuels.

The analysis of alternative fuels on example of business plan
Klimeš, Pavel ; Hartman, Ladislav (advisor) ; Topolová, Karolína (referee)
The theme of the diploma thesis is to analyze the use and prepare the business plan of establishing alternative fuel showroom cars. Showroom will focus on sales of new cars with full warranty that are primary equipped with alternative fuel engine. The idea of concentrating sales center of alternative fuel cars is unique, in the vast majority of cases sellers are becoming dealers of automobile manufacturers and their direct representatives. The sales center will be concentrated in the Prague region where the parent company has its placr of business. The theoretical part of the thesis is devoted to the characteristics of conventional and alternative fuels. In the practical part there is created a business plan of construction and operation alternative fuel cars showroom. The project is prepared on real numbers and will be used during implementation in practise.

Commercial and economic comparison of traditional and alternative fuels
Dvořáková, Monika ; Sedláček, Jiří (advisor) ; Kočan, Jakub (referee)
Negative predictions about oil stocks combined with the instability in the Middle East encourage development of alternative fuels, which would reduce dependence of the world's economies on oil. The oil and petroleum derivatives are the main dependencies for vehicular traffic, which contributes to the greenhouse gas emissions by a large part. It is therefore necessary to focus on trying to reduce the fuel consumption of cars used for personal transportation. One way to achieve this goal is, for example, to convert existing cars to run on biofuels, buying a hybrid or an electronic vehicle, or, hopefully soon, hydrogen-powered automobile. Obstacles preventing a wider deployment of such fuels and drive systems are often higher purchase and operating costs. These economic disadvantages are being gradually reduced though, and in the future we can surely expect an increase in the number of alternative vehicles on the roads.

The importance and utilization of LPG in transport
Binderová, Vanda ; Dvořák, Antonín (advisor) ; Hadrabová, Alena (referee)
The importance and utilization of LPG in transport - just the title signifies what is this bachelor thesis focused on. The first part gives a chance to learn more about liquified petroleum gasses, i.e. LPG. It comprehends information about its history, compound, processing, features and also advantages and disadvantages related with this gas. The second part is concerned with the relationship "LPG and environment". You can find there answers to questions like: Why does transport have a negative influence to environment? Which substances are emitted by fuel combustion to atmosphere? Is LPG regardful of environment? The third part is an economic one. It contains the calculations of LPG purchase costs and their economic return and also the price comparison to another fuels. The main aim of this thesis is to compare LPG with petrol and diesel oil and analyze its environmental and economic efficiency.

Alternative fuels for transport
Běláčková, Adéla ; Dvořák, Antonín (advisor) ; Hadrabová, Alena (referee)
The thesis Alternative fuels for transport is dealing with the topic of economic competitiveness and environmental advantages of alternative fuels in comparison to classical oil fuels in transport. First, the main transport related problems are discussed in detail, including the dependency on oil, emissions from transport and their impact on human health and the environment. Then, the different types of alternative fuels are presented, including the legal framework, possibility of tax exemption and subsidy financing. The comparison of emissions of alternative and classical fuels follows the logic of the whole life cycle of a fuel, using the Well-to-Wheel analysis as method. Emissions of greenhouse gases and emissions of pollutants of local importance are observed. The cost comparison is based on experience in public bus transport in the Czech Republic. Fixed, variable and total costs are compared for classical diesel, biodiesel, natural gas, LPG, hydrogen and an electric vehicle. The purpose of the study is to decide which of the alternative fuels represents a cost competitive option in comparison to classical diesel and also provides a reduction in total emissions. The results of the study are designed to help Krkonošské Metro Association to choose a suitable alternative fuel for a project in rail transport.
