Changes in the composition of the company's fleet in relation to the EU's "green deal" objectives
Tobiášová, Eliška ; Jandová, Kristýna (referee) ; Bača, Petr (advisor)
The purpose of this master thesis is to examine the so-called Green Deal and the related directives and regulations that are intended to help achieve the objectives set out in the Green Deal, as well as to analyse the fleets of the Member States of the European Union and the company with which cooperation has been established as part of this work. The thesis describes the Green Deal and its objectives. The European Union directives and plans with the aim of reducing CO2 that are currently approved or are yet to come into force are also mentioned, while at the same time they are compared with the directives and targets in force in the EU Member States, including the Czech Republic. In the following chapters, a brief description of the cars by type of fuel is given in order to follow a detailed analysis of the fleets of Germany, Sweden, Spain, Slovakia, France, Poland and the Czech Republic. This analysis is carried out using graphs and official statistics available from government institutions. Furthermore, an analysis of the company's fleet is made, summarising in tables the parameters of the vehicles available to the company. The results of the fleet analysis are also summarised in graphs based on the year of vehicle manufacture, emissions, and fuel type. In addition, an analysis of hybrids and electric vehicles currently in the company's fleet is also provided. This analysis works with data provided by the company and examines the cost of driving these vehicles, consumption, and battery usage ratio. Finally, a suggestion is made for the replacement of the current vehicles with the aim of saving emissions.

Fuels from Biomass.
Poskočil, Milan ; Píštěk, Václav (referee) ; Rauscher, Jaroslav (advisor)
Bachelor´s thesis deals with the study of the status quo use of fuels derived from biomass for automotive engines and their prospects. The goal of this work is processing the inventory of motor fuels derived from biomass, their utilization and illustrate the developments in this field. The work is focused mainly on the situation and developments in the Czech Republic.

Gasoline Direct Injection
Donutil, Jan ; Janoušek, Michal (referee) ; Dundálek, Radim (advisor)
This bachelor’s thesis deals with direct injection applicated in spark ignition engine. It explains how the system works and what are the benefits in comparison with older methods. Components description and a list of current engines are mentioned in the next chapter. The last section is focussed on the future of these motors.

Electronic control units of present SI-engines
Michna, Lukáš ; Beran, Martin (referee) ; Dundálek, Radim (advisor)
Bachelor’s thesis named „Electronic control units of present SI-engines” treats of presently known and extended electronic control systems of SI-engines, so those ones, who mainly control both fuel-air mixture preparing and its ignition in combustion chamber. These are two fundamental functions for engine running, so they are described in light of basic principle of operation and also in light of each kind of these systems and its developmental stage description. Next point is enumeration and description of single parts of electronic control system participating in engine controlling, separated to logic sections. The end of publication makes reader acquainted with most extended types of electronic control systems, their producers and elementary differences.

Direct injection systems for spark-ignition engines
Vondráček, Václav ; Rasch, František (referee) ; Drápal, Lubomír (advisor)
This bacheleor´s thesis deals with direct injection of fuel spark-ignition motors. In each chapter you can learn about principle activities injection of fuel, meet single parts and components and learn how these components work. Further, this work compare some constructional differencies of the systems of some automobile producers and observes contemporary general way of those problems with reference to future.

Determination of emissions and harmful particles of exhaust gases of CNG, petrol and diesel vehicles
Rozsíval, Adam ; Libich, Jiří (referee) ; Bača, Petr (advisor)
The thesis deals with an analyses of emission and harmful particles of exhaust fumes of automobiles with an environmental impact. More precisely, it describes the basic characteristics of current fuel types and emission produced by internal combustion engines. Next, it deals with the measures and possibilities of decreasing car traffic emission with respect to environmental impact. It also describes the current European standards for emission and the systems of the cars that are able to decrease emission. The work also deals with the measuring of emission and the methods that are used. According to the measuring methods, the analysis of exhalation is done and it is based on the data of the real car fleet. Values of the emission analyses are compared. The financial aspect is a part of the analyses.

Determination of CO2 exhaust emissions for CNG, petrol and diesel vehicles
Chytil, Ivo ; Libich, Jiří (referee) ; Bača, Petr (advisor)
The thesis deals with the topic of Carbon dioxide emissions that are created by Petrol, Diesel and CNG vehicles. In the first part of the thesis, the results of theoretical calculations are compared with the values of the manufacturer of the specific vehicle. In the second part, a specific method has been selected for calculations with real data from transport. The savings of CO2 produced by the specific vehicle are expressed in percentage – depending on the fuel used. The operating expenses from the real data are calculated and compared with hybrid and electric vehicles. In the final part of the thesis, the ratio of fleet type vehicles to the financial/ecological aspect was proposed.

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.

Study of the ecological impact of production, operation and disposal of various types of cars
Raffay, Tobiáš ; Čudek, Pavel (referee) ; Jaššo, Kamil (advisor)
This master thesis focuses on the problem of the ecological impact of the production, use and disposal of vehicles. The theoretical part summarizes the necessary theoretical knowledge for an introduction to this issue. Thus, it focuses on the entire life cycle of a passenger vehicle and the emissions associated with it. The thesis deals with the greenhouse gases released during the whole life cycle of the vehicle. Thus, from the processing of materials, the production of passenger car parts, also in the production and combustion of fuel as well as in the disposal and recycling of the vehicle. The work compares the emissions of petrol, diesel, electric and hydrogen vehicles.
