Ignition engine emissions
Semela, Lukáš ; Píštěk, Václav (referee) ; Kaplan, Zdeněk (advisor)
This thesis deals with emissions of ignition engines. The introduction acquaints the reader with the history and lays out the reasons why it is a crucial topic to be dealt with. Furthermore, the term emission is being explained as well as the description of its chemical composition, the impact on the environment and human organism. The method of measuring is also mentioned in this thesis. Then the explanation continues with European Union’s current legislation. The whole thesis is concluded with information on the additional modification of emissions and chapter that outlines the future of automobiles regarding the environment.

An emission reduction systems for vehicles with gasoline engines
Filip, Josef ; Fridrichová, Kateřina (referee) ; Böhm, Michael (advisor)
This bachelor thesis deals with ways for emission reduction of passenger cars with an ignition engine. The introduction describes the principle of combustion, the methods of preparation of the ignition mixture and pollutants that arise during the combustion. In the main part of the work, the individual specific provisions for reducing emissions used in modern vehicles are analyzed in detail. Further the examples of current emission systems for several selected cars are presented. All the findings are summarized in the following chapter. In the next part, own configuration of the emission system is described in detail, which is designed with the regard to maximum efficiency in reducing emissions. The summary together with the evaluation of the current situation and the outline of the possible direction for further development in this area are in the last part of this work.

Vegetable oil as a fuel for a diesel engine
Kuběna, Pavel ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
This thesis offers an opportunity to get closely acquainted with ignition engines running on alternative fuels. At the beginning of this work the reader is offered a wide variety of alternative fuels since born automotive industry, their basic information, features, use, and technical issues of each fuel. In the following part of this thesis, the author deals only with vegetable oil and its potential use as a fuel in an ignition internal combustion engine. It focuses on the specific conversion vehicles, their complexity, advantages and disadvantages, the overall economy of operation and risks of using vegetable oil instead of conventional diesel fuel. There is also documented performance characteristics and ecological balance of a particular target vehicle.
