The reduction of pores in welds
Němečková, Monika ; Molliková, Eva (referee) ; Němec, Karel (advisor)
This bachelor thesis dealt with the reduction of pores in the welds. These welds were in pressure stacks which are made by the Bosch company. There are Common Rail diesel injection systems in which are those pressure stacks used in. An analysis was compiled, which consisted of dates of scrap rates in the yeas 2016, and the values in which the media changed in washing machines where the pressure stacks were cleaned of grease. From the following graphs is obvious when the scraps appeared mostly and according to these results there is a proposal to reduce the porosity in the welds.

Test bend for vehicle air-conditioning testing
Andrýs, Jan ; Hejčík, Jiří (referee) ; Štětina, Josef (advisor)
The aim of this work was to design test bend for vehicle air-conditioning. This test bend should simulate interior of the car and the engine compartment. Electric motor is used to drive compressor in test bend. Air supplied to test bend is modified to extreme conditions and the volume of supplied air is the same as the car drove at 50 km/h. Main frame of test bend is made from aluminium profiles manufactured by Bosch Rexroth, which provides great modularity. Walls are made from insulated panels by ELCOM System, they have very good insulation and are strong so additional equipment can be installed inside. Construction design was made is SolidWorks with 3D models of test bend as output. Air-conditong parts which were used as samples are originally from Skoda Octavia II. For this vehicle were made calculations of heat loads. In conclusion is simple testing example for this test bend and although there are some examples for future measuring.

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.

Comfort and Safety Systems - Diagnostic Methods
Slíž, Martin ; Lapčík, Josef (referee) ; Hájek, Vítězslav (advisor)
This work deals with the division and description of the safety featutes of vehicles. Gradual entry into the safety of the crew of the car, from simple to very complex safety systems. The first part of this work deals with the basic division of safety features to active and passive systems. Here summarizes the most frequently used systems, their advantages and disadvantages. In the second part is described in detail system ABS (Anti-lock system), principle of operation, construction and other features of the system. The third part deals with the diagnosis of failures of security systems. It also included the creation of disorders, their symptoms and solutions. The last part of the two concrete examples of the use of diagnostic measurement system for ABS.

Electronic control units of present SI-engines
Michna, Lukáš ; Beran, Martin (referee) ; Dundálek, Radim (advisor)
Bachelor’s thesis named „Electronic control units of present SI-engines” treats of presently known and extended electronic control systems of SI-engines, so those ones, who mainly control both fuel-air mixture preparing and its ignition in combustion chamber. These are two fundamental functions for engine running, so they are described in light of basic principle of operation and also in light of each kind of these systems and its developmental stage description. Next point is enumeration and description of single parts of electronic control system participating in engine controlling, separated to logic sections. The end of publication makes reader acquainted with most extended types of electronic control systems, their producers and elementary differences.
