Bioetanol and Drive of Automobile
Smeták, Pavel ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
Content of my diploma thesis focuses on identification of properties and usability of nascent fuel for automotive use. It is a bio-ethanol which can be produced from renewable sources. The heart of this work is to develop methodology of experimental trials in connection with utilization of bio-ethanol E85 as a fuel for vehicle combustion engines. The aim is to perform tests with E85 and BA95 fuels in engine testing room of ÚADI FSI, to compare these trials amongst themselves and to analyze obtained results. Subsequent part of diploma thesis covers overview of general usage of bio-ethanol in road transportation.

Vliv paliva na parametry spalovacího motoru
Bajer, Šimon
At the beginning the theoretical part of the diploma thesis deals with a characteristic of fuels for ignition engines, namely to automotive petrol and a mixture of liquid petroleum gases (LPG). The next part is focused on a description of conversions of individual elements which are necessary for cars which operate on alternative fuel. As well the attention is paid to the production of emissions of exhaust fumes of these engines, to individual components of unwanted emissions, their formation and effect to people and the environment. The own thesis introduces a proper measurement of Subaru Forester car, converted into the two fuel car which is possible to work both on petrol and LPG. Operational parameters for particular fuels were observed on the tested car.

Posouzení vlivu etanolu na tepelnou bilanci zážehového motoru
Kotra, Csongor
This diploma thesis deals with the changes of individual components of the heat balance in the petrol engine with combustion for ethanol fuel. The work is divided into two parts. The first part, the theoretical one deals with the im-pact of the current state of internal combustion engines on the environment and are also dis-cussed alternative fuels. In the second part is described the methodology of experimental measurements, which were carried out on this topic in the engine testing laboratory of Mendel University in Brno. From the obtained values the final heat balance of the petrol engine run-ning on fuel containing ethanol is evaluated and compiled.

Kalkulace zavedení alternativního pohonu dopravních prostředků ve středně velkém podniku
Gelnarová, Alice
This thesis deals with the introduction of alternative propulsion vehicles in a medium-sized enterprise. The starting point of the work is time series of fuel prices modelation: CNG gas, Natural 95 and Diesel during the years 2008--2013 and a two-year prediction of the prices, including the estimation of the uncertainty associated with the development of prices. The prediction is then used in simulations to estimate the probable development and effect of investments. The result of this thesis is formulated in a general methodology for the possible purchase of new cars in the midmarket and practical applications to mid-sized company MIKROP ČEBÍN a.s.

ANALYSIS OF COMPETENTION ON THE CONSUMER'S MARKET WITH SELECTED COMMODITY
SOCHEROVÁ, Klára
For my work of market analyse from customers point of view in terms of possibility of choosing fuel I have done market research, where I compared opinions of final customers and elicited datas by Union for protecting users. Porter model helped mi to analyze competitive background in line with the market research of user{\crq}s protection{\crq}s stand-point. After the data evaluation I figured , that gas stations are competing mostly by the price and customers choose the place to refuel according to the price. Informants mostly prefer using filling station located inside the city, where they mailny refuel and also very often vehicle washer and buying groceries, as well. Most of the interviewed users feel free using their cars even after raising the fuel{\crq}s prices up and mostly offten they tank at the net of petrol stations. From the price research ensue, that refuelling stations situated close to a motorway have the highest price and fuel of a brand Shell is the most expensive. At the competitive market, there is a lot of brands, but none of them has the dominance to determine the price of the petrol.
