Development and perspectives of common rail system
Gach, Jakub ; Kučera, Pavel (referee) ; Píštěk, Václav (advisor)
This bachelor thesis is focused on the Common Rail injection system. It describes the origins of the system, its principle and the function of the individual parts of the system. It also deals with the development of individual system generations and their use. It is clear from the thesis that it is one of the best present-day injection systems that meets all the today's requirements for the design and construction of a vehicle.

Design and optimization of injector bracket
Moravec, Tomáš ; Prokop, Aleš (referee) ; Řehák, Kamil (advisor)
The present Master thesis entitled "Engineering Design and Optimization of Injector Holder" deals with the design of clamping holder, whose function is to ensure the exact position of injector system Common Rail. The shape of the injector holder is designed in the modelling program, both with respect to the installation space of internal combustion engine and also the method of manufacture. The proposed geometry is then subjected to stress analysis in the program using FEM. The final design phase is to optimize the geometry of the injector holder using the same method with the aim to reduce the weight of the component.

Development of diesel engine injection systems
Sikora, Ondřej ; Beran, Martin (referee) ; Píštěk, Václav (advisor)
The bachelor’s thesis has been created as a study on the development of fuel injection systems for diesel engines. The first part deals with the fuel system, which describes the preparation of fuel mixture. There are brief descriptions of individual system components and explains their functions. The main part deals with the injection device, which describes the specific technical solutions used in the past and in the present. Each system is discussed from a construction point of view and its functions. The last chapter describes the contemporary development of injection systems associated with complications and limitations.

Design and implementation of managed PoE injector
Frkal, Pavel ; Frolka, Jakub (referee) ; Krajsa, Ondřej (advisor)
This study deals with power supply for network devices using existing structured cabling. Various power supplies are analysed including their limitations and also deals with measuring of the consumed energy. The outcome is 24-port passive PoE injector for remote power supply of network equipment. It's suitable namely for remote devices which lacks built-in PoE support as these do not need major modifications (using passive injection). Power options including current measurement may be done via administrative web interface.

Injection System Build-in on Tractor Engine
Svršek, Michal ; Ramík, Pavel (referee) ; Dundálek, Radim (advisor)
The aim of this work is to design the installation of a new injection system to the existing tractor engines and construct new components necessary for proper function of the injection. In the following section is suggesting the location of other accessories for engine control. This is an injection system with a pressure reservoir "Common Rail" and all its components are created in modeling environment PTC Creo 2.0. Designed components are tested for strength and they are subjected to modal analysis.

Application of Pressure Accumulator Injection System on Six-cylinder CI Engine
Pacovský, Tomáš ; Štěpánek, Karel (referee) ; Dundálek, Radim (advisor)
This master's thesis deals with application of modern injection system Common Rail on six-cylinder CI engine. One of aims of thesis is to get a large overview of pressure accumulator injection system and explore the development in this area. Among main aims of the thesis belong a new construction layout in Pro/Engineer, accomplishing of static and dynamic analyse of most important parts via the finite element method (FME) and necessary control calculations. Finally, the design documentation of new most essential designed parts will be made. During making the thesis necessary source materials obtained from Vývojový ústav traktorů a.s. of Zetor Group company was made use of.

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.
