Part Production Process Videoanalysis
Svobodová, Veronika ; Hromková, Ivana (referee) ; Knoflíček, Radek (advisor)
The bachelor thesis is describing mainly elimination of wasting time and with that also financial means on a welding line of high pressure tanks Common Rail in the company Bosh Diesel s. r. o. With detailed way is described procedure analysis of contemporary status and subsequent analysis, which is enable to search possibilities and potentials to increase productivity of work on productive line. With an application of tools ViCTA, we successfully found the searching potential in lost time in welding industrial robot’s line. Then was suggested the optimal solution, which comply the conditions of achieving minimal costs for current unlimited way of production technology on the welding line.

Engine Diagnostic
Holeš, Cyril ; Beran, Martin (referee) ; Svída, David (advisor)
The thesis is focused on determining the methodology of engine diagnostics for vehicles with common rail direct fuel injection. The first section describes the communication between the diagnostic tools and control units, and the common rail system for diesel engines. The next section specifies the procedure for the acquisition, processing and analysis of data using selective diagnostic tools along with software in a numerical computing environment. Subsequently, from the results, the equivalent electronic control of the fuel injection quantity is established for the purpose of research, vehicle servicing. The results may also allow for additional observations to be made.

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.

Robotic manipulation with Laser Welded Common Rail during the laser welding process
Bužga, Petr ; Šubrt, Kamil (referee) ; Knoflíček, Radek (advisor)
This master’s thesis deals with a description of Laser Welded Common Rail, which is produced by the company Bosch Diesel, s. r. o. in Jihlava. The theoretical part is focused primarily on a proposal for an industrial robot which would be manipulated with Common Rail during the laser welding process. The practical section is concerned with changes in the current paths of the robot to reduce production times, and to avoid using the same parts of the robot for the whole duration it is being manipulated with the Common Rail. At the end of this master's thesis is a techno-economic evaluation of previous alternatives, and it determines the appropriate option for robotic manipulation with the Common Rail during the laser welding process.

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.

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.

Effect of engine load on the output parameters of the tractor kits
Paulmichl, Roman ; Svída, David (referee) ; Bauer, František (advisor)
The thesis deals with the current situation in the construction of tractors, particularly engines and accessories. The work includes a methodology for measuring tractor rigs in traffic as well as methodology for plough/plow kits measuring. The measured values were tabulated, graphically presented and analysed. The thesis provides an overview of the issue of the combustion engine load placed on the engine by working conditions in transport, during primary soil tillage with different modes of operation of the tractor set. The thesis aim is to find out the practical effect of the engine load on the monitored parameters and to indicate possibilities for achieving higher efficiency in tractor units with minimum fuel performance
