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.

CI-engines Fuel Systems
Duda, Martin ; Janoušek, Michal (referee) ; Dundálek, Radim (advisor)
This bachelor thesis is about fuel systems, especially is focused on the injection system Common rail. The most usable injection system at this time, which is almost twenty ye-ars at the market and during the time system is getting better and more inovative. In addition to description of main parts of the system, are at this thesis included inovations of last five years and reflection of future.

Injection Systems of Commercial Vehicles
Horníček, Petr ; Prokop, Aleš (referee) ; Dundálek, Radim (advisor)
In this thesis I describe the fuel system components and their function. Furthermore, there is an overview of the most commonly used injection systems with the principle of operation, advantages and disadvantages of the embodiment. There is also processed the issue of the emission standards. This thesis contains a list of the world's leading manufacturers of commercial vehicles and their injection systems. Finally there is a reflection on the future development of injection systems.

Ejectors and it's utilization in industry
Zejda, Vojtěch ; Hájek, Jiří (referee) ; Vondál, Jiří (advisor)
This work aims at introducing ejector pumps. It describes the working principle, advantages and disadvantages and restrictions of their usage in various applications. Main disadvantage of ejectors is the low efficiency which limits the usage only in specific applications where it is not considered to be a crucial factor. Therefore, examples of usage of various ejectors in industrial processes are listed further. Last but not least, in these examples are also demonstrated difficulties and reasons why it is favourable to use an ejector rather than other types of pumps. Further off, this work deals with design methods of ejectors and compares their suitability. It appears that not all the methods are suitable for ejector design, because it depends greatly on presumed shape of a certain ejector. In the end, there is compared energy intensity of an ejectors and common centrifugal pumps and confirms energy disadvantage of ejectors.

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.

Common Rail for Six-cylinder CI Engine
Božik, Michal ; Ramík, Pavel (referee) ; Dundálek, Radim (advisor)
This thesis deals with the installation of high-pressure common rail injection system for six-cylinder tractor diesel engine. In the first part of the thesis is dismantled issue injection systems and related aspects. The next part is the installation of a fuel injection system, which involves placing components common rail system, the implementation of necessary interventions in engine design and the design of new components. The final section effect control calculations and stress analysis of new injection system components.

Combustion Engine Ignition and Fuel Injection Control (Motormanagement)
Škrabal, Martin ; Mikulčík, Aleš (referee) ; Hájek, Vítězslav (advisor)
Undoubtedly the most important and absolutely essential electrical systems located in vehicles which are powered by internal combustion spark-ignition engine is the ignition system of the engine. Without this the engine, or the whole vehicle can not operate properly. Since the beginning of spark ignition engines ignition system executing a complex and long term development effort driven by the best function of the engine. Unlike the ignition, which had to work from the outset the development of spark ignition engines has been to introduce more to the use of injection in the 70 the 20th century. From simple control systems, ignition and injection on the mechanical principle of working out the development of electronic management units. In most modern combustion engines is the management of the ignition and injection is carried out using a common system with one central control unit. Most of this type of system-Motronic system from Bosch-used today in different variations large number of producers cars. In history was the main objective of the management system to achieve the highest possible power, now coming oil crisis be brought to the forefront of the fuel consumption and the implementation of emission standards (in the Czech Republic EURO standards).
