Emission standards for IC-engine vehicles and emission test systems
Náhlík, Tomáš ; Pech, Ondřej (referee) ; Štětina, Josef (advisor)
This bachelor thesis deals with the issue of emission standards and emission measurements with contemporary motor vehicles. Introduction acquaints reader with the reason it is actually necessary to address this issue and what are the main negative components of emissions by motor vehicles. Effects of such components on human health and the environment are also included. List of historic and of course current emission standards both from within the European Union and globally follows. The thesis concludes with an overview of analytic methods, tests and test techniques focused on emissions by motor vehicles.

Emissions from biomass combustion
Vaněk, Michal ; Lisá, Hana (referee) ; Baláš, Marek (advisor)
The thesis deals with harmful substances originating as products of biomass combus-tion and possibilities of reducing their emissions from boilers for household heating. First of all, biomass is introduced and a description of important fuel properties in terms of its combustion is given. Secondly, the characteristic of the combustion process and origination mechanisms of individual substances are presented. This is followed by a description of the properties of these substances and their impacts on human health and the environment. The purpose of the next chapter is to present the reader with current legislation addressing the emissions of small boilers. Then a separate chapter describes possible methods that can be used to reduce emissions of these devices. Finally, several measures in the form of modifications and devices, capable of reducing harmful emissions of small boilers are given.

Fuel Systems with Pressure Accumulator
Buchta, Martin ; Janoušek, Michal (referee) ; Dundálek, Radim (advisor)
This bachelor's thesis is focused on the Common Rail injection system for diesel engines. There is described each component, function principle and history of the system. It deals with currently used systems, theirs application in passenger cars engines and theirs effect on emissions in exhaust gases. It is concluded that the Common Rail injection system is currently the best, which we can use in passenger's cars diesel engines.
