The High Pressure Fuel System Application for CI-engine
Ševčík, Ondřej ; Prokop, Aleš (referee) ; Dundálek, Radim (advisor)
This thesis focuses on the design of new high pressure injection system application on diesel engine. The design came from company Zetor’s demands. For this application was chosen system Common Rail supplied by company Bosch. Assignment was separated into several tasks. Research of suitable components for low pressure section, design of waste system and high pressure injection tubes design including injector clamping. Due to injectors used in this system was necessary to redesign cover for valves and even new system to lead wires from outside of the engine to injectors. Injector is attached by screw connection, which is composed from screw and clamping jaw. These parts are subjected to an analytic calculations. Clamping jaw of injector is even subjected to a FEM analysis, which focuses on fatigue life. Finally, the drawings were documented.

Luminance scanning of luminaires and light sources
Ševčík, Ondřej ; Baxant, Petr (referee) ; Škoda, Jan (advisor)
Práce se zabývá měřením křivek svítivosti světelných zdrojů a svítidel konvenčními a nekonvenčními metodami. Úvodní část práce je věnována popisu zrakového systému a základních fotometrických veličin. Hlavní teoretická část je zaměřena na popis současných metod měření křivek svítivosti a nových metod měření pomocí jasového analyzátoru. Současně jsou pro jednotlivé metody uvedeny zdroje nejistot, které ovlivňují výsledky měření. Těžiště práce spočívá v návrhu metodiky měření křivek svítivosti z jasových skenů svítidla a následném ověření tohoto postupu vlastním měřením. Dále bylo provedeno srovnání naměřených výsledků navrženým postupem, s výsledky konvenčního měření na goniofotometru s luxmetrem.

Household heating systems
Ševčík, Ondřej ; Bok, Jaromír (referee) ; Bartošík, Tomáš (advisor)
Main goals of this bachelor thesis are economic evaluation of four chosen technologies of heating, and heating system design. Introduction deals with problem of heating in a family house, types of heating systems and main influences affecting the choice of heating system. The third chapter discusses main components of heating systems. Each component of the system is characterized and described. The most important parts include heating source, which are divided by type of fuel. The fourth chapter describes other possibilities of austerity meassures, which reduce heat loss and heating costs. There is a mention about government subsidies. The fifth chapter shows the shares of different heating sources, that are used in residential houses. In the last chapter, the computation of heat loss in the particular object is done. Based on the heat loss computation floor and radiator heating system is proposed. Four heat sources are chosen for the object (gas boiler, heat pump, biomass boiler and electric boiler with acumulation tank) and the purchase and the operating costs are computed. Conclusion of the chapter is devoted to the economic balance of the four heat sources and their comparison in the return of investment.

Methodological guide and digitization of gear pump
Ševčík, Ondřej ; Nevrlý, Josef (referee) ; Nečas, David (advisor)
The aim of this bachelor thesis is to provide a methodological quide of U10 type gear pump. In the first part of the thesis, analysis of individual pump components including its main parameters is presented. The next part is focused on the identification of the defect suggesting the instructions for the reparation. All the operations such as dismantling, inspection, reparation, and assembly are described in a detail in a form of the technological processes. After the reparation, an operating test was conducted to verify the functionality of the pump. In addition, all the components of the pump were digitized by using SolidWorks CAD system. The last chapter provides FEM analysis of the cogwheels contact. For this purpose, computational system ANSYS Workbench was used.
