Application of Pressure Accumulator Injection System on CI Engine
Šiška, Adam ; Štěpánek, Karel (referee) ; Dundálek, Radim (advisor)
This master’s thesis deals with building the most modern injection systém Common-Rail for four-cylinder tractor diesel engine. The following application is a conversion from a obsolete system with inline injection pumps. Because the costs for this conversion must be minimized, that it is effort of minimal intervention in engine design. First this master’s thesis focuses on the theory of injection systems of diesel engines and related things and then the thesis shows the design conversion supported analytical calculations and FEM analysis of newly designed components.

Technology of Selective Catalytic Reduction
Kudlík, Michael ; Janoušek, Michal (referee) ; Dundálek, Radim (advisor)
This bachelor thesis is focused on technology of selective catalytic reduction. The technology was created as a result of introduction of strict emission limits which manufacturers with this technology reach. First part of this thesis deal with the composition of the exhaust gases, where are dismembered the various elements, and then are given here the European emission limits.Then is thesis focused on ways of reducing emissions of diesel engines which describes the function of exhaust gas recirculation and a function of selective catalytic reduction. Then are described development systems selective catalytic reduction. The conclusion consists of the use and application of Automobile Manufacturers.

Emission Standards
Nevtípil, Jakub ; Prokop, Aleš (referee) ; Dundálek, Radim (advisor)
This bachelor’s thesis deals with the European emission standards of internal combustion engines. There is a tightening of standards in recent year generally. The former part of the thesis contains description of specific pollutants that are exhaled into the air. The second part is focused on main emission standards for road and non-road engines. The last chapter deals with an overview of the ways and appliances for reducing the emissions.

EURO 6 Emission Standards
Velešík, Aleš ; Prokop, Aleš (referee) ; Dundálek, Radim (advisor)
Bachelor´s thesis is focused on the approach the issue of Euro 6 emission standards. There is a general description of the tests, which the manufacturer must undertake and successfully complete to produce cars at this emission level. There is also a description of the harmful substances produced from the exhaust system of a car and an overview of the structural elements to reduce them. In conclusion, the reflection on the issue of emission standards and their constant tightening.

Possibilities of waste heat recovery from internal combustion engines
Křivák, Petr ; Pospíšil, Jiří (referee) ; Brázdil, Marian (advisor)
Increasing demands for vehicular traffic to reduce the environmental impact and consumption of fossil fuels, led an effort to increase the efficiency of the combustion process and the car as a whole. One way to achieve this is to use the waste heat of the combustion process, especially waste heat of exhaust gases. This heat can be converted into electrical energy. Consumption of electricity in modern cars is increasing. The presented work deals with the possibilities, how to using waste heat of exhaustgases from internal combustion engine. Focused on application of producing electricity. The paper analyzed the current state of car traffic, and then provides an overview of possible technological solutions using waste heat of exhaust gases. The main part is devoted to thermoelectric generators, their construction and possible design. In conclusion is made the energy balance with use thermoelectric generator.

Automotive Diagnostic Systems
Bůžek, Václav ; Beran, Martin (referee) ; Ramík, Pavel (advisor)
This thesis is written to make a review abstracting of contemporary systems of automotive diagnostics. It is aimed at the principles of serial and parallel diagnostics and informs about contemporary norms. It brings nearer the basics of used on-board diagnostic systems, including the diagnostics of its components. The thesis also exemplifies the practical functions and possibilities on the elementary diagnosing by using the diagnostic software SuperVag.

Usage exhaust gas in combustion engine for improvment engine quality
Fusek, Petr ; Drápal, Lubomír (referee) ; Rasch, František (advisor)
This bachelor´s thesis contains information on how to use exhaust gas of engines. It describe the usage of kinetic and thermic energy of exhaust gas which is taken from the engine without any usage. This study includeds basic technical parameters and descriptions of giving analysis and their usage in practice. This bachelor´s thesis assesses theoretical possibilities of exhaust gas and their occurence and structure
