Optimation and Innovation of Family Houses Heating
Dubnický, Ladislav ; Špiláček, Michal (referee) ; Lisý, Martin (advisor)
The aim of this bachelor thesis is to make a summary of knowledge of today´s modern heating systems for family houses. Each types of systems are compared to each other from economic, operating and ecologic point of view. At the end of the thesis there is a model conversion of energetic costs for specific family house and projection of new heating system.

Analysis of flue gas in automatic domestic boilers for agropelet
Minář, Marek ; Lisý, Martin (referee) ; Jecha, David (advisor)
The objective of the presented bachelor thesis is flue gas analysis during combustion of agropellets in automatic household boilers. Emphasis is placed on the description of biomass as a fuel, the ways of using biomass for energy purposes, alterations of biomass, production and properties of alternative pellets, automatic boilers and burners for combustion of specific fuel types. The end of the theoretical part is focused on standards and regulations for boiler operation. The practical part verifies the formation of emission on small sources of pollution and determines the concentration of solid and gaseous pollutants. The end of the practical part pursues with comparison of results with legislative requirements and calculation of boiler efficiency.

Fuel additives for modern internal combustion engines
Mach, Petr ; Kaplan, Zdeněk (referee) ; Píštěk, Václav (advisor)
This bachelor thesis is devoted to thorough research of fuel additives, especially their effect on deposits in internal combustion engines, wear and service life of the engines and their effect on fuel consumption. The first chapter briefly informs about automotive fuels and explains the used terms in this work. The next chapter describes the types of fuel additives and their use. The third chapter deals with the deposits in the internal combustion engines and their reduction using detergent additives. The fourth chapter focuses on the types of wear and places where arise. This chapter also aims to prove the positive effect of additives on the engine components service life. The last chapter focuses on the fuel consumption and importance of additives in world fuel consumption.

Vehicles with CNG drive units
Otipka, Václav ; Svída, David (referee) ; Píštěk, Václav (advisor)
The bachelor’s thesis is devoted to vehicles with CNG drive units. The introductory part focuses on the analysis of fuels that are used for propulsion of piston combustion engines. Not only the very expanded fuels but also unique fuels are analysed. The main part of the thesis describes the construction of mass-produced vehicles powered by natural gas. There are analysed the individual function elements of the vehicle which are different from common vehicles on conventional fuels. Part of the thesis is about CNG vehicle operation including ecological and safety impacts. The whole thesis concludes the current offer of cars on the domestic market.

Analysis of ash from fireplace
Drápela, Jakub ; Špiláček, Michal (referee) ; Hrnčířová, Michaela (advisor)
This bachelor thesis should familiarize readers with the size of analysis of ashes of fireplace inset. The work is posssible to divide into two parts, when the first one is devoted to a description of fireplace insets, fuels and subsequent processes during burning in fireplace insets and to individual methods used for size analysis of particles.The other part is focused on practical measurements of individual samples of ashes and subsequent evaluation.

Hodnocení paliv pro spalovací motory ve vztahu k životnímu prostředí
Vančatová, Šárka
The name of this diploma thesis is „Evaluation of combustion engine fuel and its influence on the environment”. At the beginning there is a brief history of fuels. After that there is a chapter which divides fuels according to their state thus they are separate to three main types (solid state, gaseous state and liquid state). There are described main characteristics in the next part of this thesis which are heat of combustion, bulk density, dosage, volatility, resistance to detonation burning and mainly octane and cetane number. There are described currently used fuels for combustion engines right after the characteristic of fuels. These fuels are divided to fuels made of petroleum (gasoline, diesel, and LPG), fuels made of natural gas (CNG, and LNG), biofuels (bioethanol, biomethanol, vegetable oils – FAME and synthetic diesel fuel) and there is also an independent group of hydrogen. Thereafter are described European emission standards. The practical part of the thesis is focused on an analysis of previously mentioned fuels and there is a biggest focus on production of carbon dioxide. Other emissions are evaluated as well such as carbon monoxide, hydrocarbons and NOx gases. The analysis is done on classical fuels like gasoline and diesel and also on alternative fuels such as CNG, LPG, E85, FAME and hydrogen. In the end there are tables and graphs which contains production of flue gases.

Emise spalovacích motorů ve vztahu k životnímu prostředí
Cahová, Kateřina
This bachelor thesis concerned with emissions issue that arises during the burning of fuels in combustion engines, considering the environment. In introduction there are generally described burning fuels, then chapter about different types of fuels follows. The most important part of this thesis concerned with emissions having impact on the environment and possibilities of reducing their negative impacts on environment, atmosphere and human life. Also, it deals with analysis of individual data relating to emissions in the Czech Republic.

Pěstování olejnatých rostlin pro výrobu bionafty v České republice
Kobzinková, Nikola
The bachelor thesis deals with the history of the use of plants for the production of fuels, specifically for diesel engines. There are described crop rotation in the growing of oil plants and consequently their use in the field of transport, ie in the field of biofuels. It will describe the economic and energy demands of biodiesel production, which will give an overview of the development of financial support in the production and subsequent distribution of biodiesel produced. At the end, with the help of the obtained sources, a clear conclusion will be drawn, which also relates to the problem of substituting biodiesel-based fuels.
