High Pressure Injection Systems
Břoušek, Roman ; Otipka, Václav (referee) ; Dundálek, Radim (advisor)
This thesis is based on high pressure injection system mostly for commercial vehicles. The aim is to describe direct injection systems on specific drive units with methods of reducing emissions and their common issues. Gradually, the parts of injection system are described including their function. By comparing direct injection systems of gasoline and diesel similarities can be notice by aspect of their function. Finally is good to mention onset of electrification and thus develepment of injection systems, which are retreat by combination of financial and technological aspects.

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 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.

Integration od robot in production of pressure tank for common rail system
Krejčí, Monika ; Tůma, Zdeněk (referee) ; Knoflíček, Radek (advisor)
This diploma thesis is about integration process of assembly line automation on rail assembly. In the beginning is introduced Bosch Company, then follows up theoretical part about automation and assembly lines. After theoretical introduction continues description of current state of rail assembly and choice the best line for automation and its detailed description. After that, the work deals with finding of the best solution for line automation. Found solutions are evaluated using the decision matrix. After the best one of them is chosen. There is also calculation of investments, because the one of important conditions is, that payback period has to be less than two years. Next step is choice of the most suitable supplier and integrator, which can cope with all requirements. At the end of thesis is analysis of risks done and thanks to this, are potentials for improvement of workplace safety found.

Engine Motormanagement Software
Kuda, Roman ; Kuchyňková, Hana (referee) ; Hájek, Vítězslav (advisor)
Increasing requirements and claims on running of motor vehicles contributed to development of new systems on the mixture preparations of fuel and ignition. Cardinal causes, which led to the very intensive research and later introduction of superior systems of injection and ignition, where fulfilment of stricter emission limits, lower fuel consumption at prezent engine-power increase and engine torque. The conception of the classical gas-engine was not changed over the past few years. The supervising elements as ignition and injestions of engines are continuously changed.

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.

Fuel Systems with Pressure Accumulator
Buchta, Martin ; Janoušek, Michal (referee) ; Dundálek, Radim (advisor)
This bachelor's thesis is focused on the Common Rail injection system for diesel engines. There is described each component, function principle and history of the system. It deals with currently used systems, theirs application in passenger cars engines and theirs effect on emissions in exhaust gases. It is concluded that the Common Rail injection system is currently the best, which we can use in passenger's cars diesel engines.

The fuel pump improvement, possibilities and limitation
Novotný, Vladimír ; Veselka, František (referee) ; Bušov, Bohuslav (advisor)
This thesis deals with common rail injection systems used at diesel vehicles. It contains an overwiev of manufacturers common rail systems, their construction and differences. The second part contains a description of Bosch Common Rail electrical and electronic components, and described ways of pressure control. Last chapter summarizes the possibilities for development and improvement of some parts of the system in the future.
