Automotive Diagnostic Systems
Bůžek, Václav ; Beran, Martin (referee) ; Ramík, Pavel (advisor)
This thesis is written to make a review abstracting of contemporary systems of automotive diagnostics. It is aimed at the principles of serial and parallel diagnostics and informs about contemporary norms. It brings nearer the basics of used on-board diagnostic systems, including the diagnostics of its components. The thesis also exemplifies the practical functions and possibilities on the elementary diagnosing by using the diagnostic software SuperVag.

"Start&Stop" system spark ignition engine, passanger car implementation
Kubiš, Milan ; Hejtmánek, Petr (referee) ; Blaťák, Ondřej (advisor)
My bachelor work describes a system implementation Start&Stop and its usage in passenger cars with gas engine. The work details reasons for the usage of this system and technically describes the basic elements. It shows different constructions of the systems, their advantages and disadvantages, both from the point of the influence over the car movement and in terms of the motoring comfort and the safety of running, especially in the urban environment.

Waste Incineration II: Flue Gas Cleaning Equipment
Albrecht, Jan ; Juřena, Tomáš (referee) ; Turek, Vojtěch (advisor)
Description of the thermal treatment methods dealing with wastes is a major concern of the present study. Emphasis is placed on equipment and methods for purification of waste gases created in the process of thermal destruction. Considering that the efficiency of flue gas treatment is dependent not only on the activity of flue gas equipment elimination, but is completely dependent on a whole unit of operating incinerators, we can not focus exclusively on the block of flue gas treatment. Therefore, in the study there are given a description and drawings of equipment for thermal processing of waste. First part of this thesis addresses the koncept the concept of "waste", its definition, classification and possibilities for treatment or recovery. The whole thesis is also written with emphasis on current legislation relating to waste and thermal processing.

Boilers with medium capacity for biomass combustion of czech and foreign production
Habán, Tomáš ; Kropáč, Jiří (referee) ; Pavlas, Martin (advisor)
The main objective of this work is to focus on biomass as one of the components of renewable energy sources for the production of thermal energy by combustion. The introduction of work maps the current state of biomass used in the Czech Republic. It evaluates options for future uses for biomass and also the size of the potential in the natural conditions of the Czech Republic. It also views this renewable resource from the point of view of energy conception and evaluace the government positron on this issue. Next part deals with the combustion of biomass and with the use of created thermal energy. It ruminate a problem of pollutants and shows values for emission limits results from the legislation. It shows ways of using this thermal energy and the associated production of electrical energy including an overview of the possibilities of its evaluation. The last part of this work describes a comparison between biomass boilers from Czech and foreign producers in the range of rated output 1 to 3 MW. It divides boilers in terms of legislation and shows the obligations and conditions attached to the operators of biomass boilers. It outlines the biggest application of boilers with medium capacity for biomass combustion in the Czech Republic.

Pollution control strategies and techniques for combustion processes
Kunc, Vlastimil ; Chlápek, Petr (referee) ; Bělohradský, Petr (advisor)
Bachelor’s thesis deals with the problems of combustion process. The work gives the overview and the description of individual design parameters of the combustion facility. The analysis of the influence of design parameters on emissions formation is followed by the description of individual kinds of emissions and their impact on the environment. Next the most used reduction techniques are described. The work is closed by the overview of the emission limits in the Czech Republic.

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.
