An aftertreatment system for the passenger vehicles with a gasoline engine
Hána, Michal ; Fridrichová, Kateřina (referee) ; Böhm, Michael (advisor)
This thesis concentrates on the issue of reducing emissions from passenger vehicles with a gasoline engine. The introduction describes the individual emission components, their origin and impact on the environment and human organism. The main part of the thesis concentrates on possibilities of reducing emissions. The function and design solution for each component of the emission system is described. Furthermore, the specific solutions for several selected representatives from diverse vehicles categories are stated. These solutions are evaluated and custom configuration is designed given the selected parameters. In the conclusion are summarised the results of the thesis.

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.

Cylinder deactivation of a spark-ignition engine
Fridrichová, Kateřina ; Píštěk, Václav (referee) ; Drápal, Lubomír (advisor)
This thesis focuses on a technology called cylinder deactivation. The technology helps reducing emissions and fuel consumption. The first part summarizes the possibilities of application of the cylinder deactivation technology as well as advantages resulting from combination with other technologies. The thesis also consists of two design options for valvetrain in inline four-cylinder engine and the results of simulations of dynamics of its cranktrain.

Comparison of life-cycle emission produced by cars
Plott, Patrik ; Ušiak, Michal (referee) ; Fridrichová, Kateřina (advisor)
This bachelor´s thesis of research nature deals with comparison of emissions of individual types of passenger car´s powertrains in terms of their entire life cycle. The goal was to describe current emission regulations of passenger vehicles, various types of power units they use, and emissions that are created in manufacturing, using and disposal of these vehicles. The comparison includes not only different types of internal combustion engine vehicles, but also electric vehicles. In conclusion were these power units evaluated based on emission considering current situation.

Cylinder Deactivation for Internal-combustion Engines
Fridrichová, Kateřina ; Janoušek, Michal (referee) ; Drápal, Lubomír (advisor)
This bachelor’s thesis focuses on a technology reducing fuel consumption and emissions called cylinder deactivation. The evolution of the technology is described in the first part of the thesis together with explanation of the nature of fuel savings. The description of consequences associated with usage of the technology and possible design approaches for gasoline engines are written in the following part. The thesis also incorporates the results of test performed on diesel engines, where the technology is not currently in production. The last part includes other components used in engines with cylinder deactivation, especially vibration absorbers, together with some examples of application of this technology.

Recent trends in electric drive units of passenger vehicles
Drapela, Lukáš ; Fridrichová, Kateřina (referee) ; Böhm, Michael (advisor)
Bachelor’s thesis is focused on providing a comprehensive overview of the current architecture of electric drivetrains for passenger cars with offering specific examples and their critical evaluation. The first part of the thesis aims to describe the function of several different types of electric motors. This thesis continues with a description of the architecture of hybrid vehicles followed by vehicles powered purely by electricity. The final part of the thesis is dedicated to current trends in increasing efficiency and range of electric cars. This part is then supported by a calculation of energy demand of the electric vehicle model for selected comparative parameters using the GT-Suite simulation programme.
