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.

Design of Device for O-rings Fitting on Overflow Valve of Injection Pump
Matula, David ; Beran, Martin (referee) ; Ramík, Pavel (advisor)
The thesis deals with the problem of threading o-rings on the overflow valve of the CP4 injection pump. The thesis was prepared for the company Bosch Diesel s.r.o. in Jihlava. In the thesis, first of all, an introduction of the company and their products is given. In the next part of the thesis, an analysis of the current state of the workplace is made. This is followed by market research in the field of automated o-ring threading. This research served as inspiration for the design of the threading head. The constructed head was manufactured and tested at the test site. After testing the head, several variations of the o-ring threading station were developed. A multi-criteria method was used to select the most suitable variant. A design concept of the workstation was developed for the winning variant. The resulting concept was evaluated from an economic and technical point of view.

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 System for 4-cylinder CI-engine
Ošmera, Petr ; Svída, David (referee) ; Dundálek, Radim (advisor)
This diploma thesis with a view to „common rail system for 4-cylinder CI-engine“ deals with the application of modern injection system „common rail“ to already existing compression-ignition tractor engine. The diploma thesis treats of the most necessary adjustments related with the replacement of injection systems which was solved in the way of the minimum adjustments. This kind of solution deals with an economic aspect of the problem. The reconstruction contains the engineering design of development of high pressure components and the suitability of their placing on engine.The primary adjustment of the application of system „common rail“ for existing tractor engine confirmed the possibility of this reconstruction.

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.
