European emission legislation
Rytina, Matěj ; Kučera, Pavel (referee) ; Píštěk, Václav (advisor)
The aim of this bachelor thesis was to write about exhaust emissions and their influence on environment, briefly sum issue of emission standards up and mainly sum existing facts about the “Dieselgate” affair up. I wanted to objectively evaluate this issue in my bachelor thesis. Asset of this thesis was mend to be in fact that this affair has not been academically covered yet.

Stage IV Emission Standards for Tractor Engines
Vít, Jakub ; Beran, Martin (referee) ; Dundálek, Radim (advisor)
The aim of this bachelor thesis is to explain the mechanism of injection of carbamide and its installation on a vehicle. The first part of this work deals with the reduction of pollutants in the exhaust gases and with the emissions standards which limit the level of pollutants in the exhaust gases. The second part consists of an overview of tractor brands available at Czech market and their classification based on the type of system they use on their new models to reduce the pollutants in the exhaust gases.

Possibilities of Injection System Modernizing in Zetor Tractors
Starý, Radek ; Svída, David (referee) ; Dundálek, Radim (advisor)
Bachelor thesis deals with injection systems used on tractor’s combustion engines. Thesis contains a summary of various kinds of injection systems, principle of function and describes the differences among various injection systems. In the second part is an overview of the most important tractor’s manufacturers sailed on the Czech market and the description of the technology solution used on the engines. In the end is the summary of possible solutions of injection systems and the following improvement for the future.

Diesel Particulate Filters
Haratek, Marek ; Janoušek, Michal (referee) ; Dundálek, Radim (advisor)
This bachelor thesis is focused on creation of particulate matter during combustion in diesel engines and their trapping in DPF systems. The first part deals with particulate matter and emission standards in Europe and USA. There is described filtration principle, types of regeneration and DPF variants in the second part. Afterwards the thesis is concentrated on particular DPF system applications used by representative car makers and there is also introduced range of products of some diesel particulate filter manufacturers, including description of construction variants and used regeneration technologies.

Stanovení vybraných fyzikálních vlastností tuhé fáze AdBlue\regm{} v závislosti na teplotě
JEDLIČKA, Václav
This bachelor´s thesis is focused on physical properties of AdBlue? allied with problematics of its freezing in DNOx components. The thesis describes functions and scheme of DNOx system, explanation of emission standards and also includes a chapter about AdBlue?. Practical part of the thesis is focused on measurement of compressive strength of solid AdBlue? together with construction of system for freezing tests and temperature tracking.
