The issue of evaluating the production of pollutants in the exhaust gases of passenger cars
Jančář, Radek ; Bazala, Jiří (referee) ; Beran, Martin (advisor)
This thesis analyses evaluation of homologation measurment of pollutant production of passenger car in the European union. The measurement methodologies used are described chronologically, including the standarts that describe them. Along with the improvements and disadvantages that the new requirements have brought, it also deals with the impact on new cars and the trends that have affected emisson requirements in the field of car development. The main part of the work deals with the measurement of real driving emissions RDE and describes the issue of this breakthrough methodology.

Overview of Rally Racing Vehicles
Listoň, Martin ; Blaťák, Ondřej (referee) ; Hejtmánek, Petr (advisor)
This work is focused on compiling an overview of race cars for rally car competitions at the national and international level and the division of vehicles into specific categories. Subsequently, the technical modifications of vehicles of individual categories are briefly described. Furthermore, the representation of individual manufacturers and their market share is summarized. The next part is a statistical overview of vehicles in terms of age and modern technology. The aim of this work is to analyze the market and find out in which potential production area a new producer could succeed.

Normative Requirements for Automotive Restraint Systems
Kučera, Jonáš ; Dadák, Leo (referee) ; Rochla, Tomáš (advisor)
This diploma thesis deals with the normative requirements on the activities of restraint systems. It includes biomechanical limits of the human body, restraint systems, description of the principle of their action and legislation. Legislation, particularly regulations of ECE and EC directives defines the normative requirements on the activity of restraint systems in the context of the approval process. There are described two types of restraint systems: seat belts and airbags in details. There are created simulations of crashtests and reviewed influence of using restraint systems on elimination of negative phenomenon of car accidents.

The effect of manufacturing inaccuracies on the final light intensity distribution of an automotive headlamp
Březnová, Tereza ; Lysa, Bohuslav (referee) ; Novotný, Jan (advisor)
The thesis deals with the issue of headlamp defects arising during production and their impact on the resulting light trail. The thesis describes and analyses defects arising during individual correction loops. Their analysis was carried out in order to provide measures for other projects. The main defects that have been assessed include the position of the light source, the quality of the optical surfaces and the associated quality of the plating, inaccuracies of the optical surfaces, dimensional variations due to installation technology and defects on the cover glass. The proposed measures concern the pressing tool, accuracy of machining and surface polishing. The thesis also includes designing solutions for quick identification of the surface quality of the cover glass by remote projection. Individual defects were described by their originators, their seriousness and their reparability. Based on this information, recommendations for production are proposed.

Issues of legislative tests in the assessment of exhaust pollutants
Weidenhöfer, Jan ; Svída, David (referee) ; Beran, Martin (advisor)
This work deals with issues of emissions in passenger cars with a focus on legislative tests in the European Union. At first, the reader is briefly informed about the historical context and current legislative requirements for modern passenger cars in Europe and other parts of the world. The following section is devoted to the NEDC driving test, with special emphasis on describing and evaluating the methods by which manufacturers have been able to artificially reduce their car emissions. The main part of the thesis are chapters devoted to newly introduced measurement using global WLTP methodology and especially measurements in real operation RDE. An important part of these chapters is the analysis of advantages and disadvantages of new methodologies and the problems of their implementation.

Technická exploatace a ekonomická efektivita traktorových souprav v dopravě
Svoboda, Michal
The thesis gives the reader a comprehensive overview of the construction of agricultural tractors with regard to their use in transport and their economic evaluation. The theoretical part deals with the construction of modern tractor and homologation for the road traffic. The conclusion of this thesis is dedicated to the practical measurement of the tractor set in transport with respect to the maximum speed of 50 km.h-1, 40 km.h-1 and 40 km.h-1 at the reduced engine speed.
