Development of Laser Welded Common Rail with Radial Connected Pressure Sensor (RPS)
Šantavý, Ivo ; Skrutek, Ivo (referee) ; Ramík, Pavel (advisor)
This dissertation deals with a development of a laser welded common rail with a radially attached RPS sensor of pressure. The new concept required by Bosch Diesel s.r.o. Jihlava should be more modifiable and it should be easily integrated with the engine compartment. In this dissertation I suggested a number of concepts that I further analysed, verified in appropriate software, developed, and finally narrowed the selection down to the most suitable solution, which is recommended and justified in the conclusion.

Utilization of Waste Vegetable Oils as an Alternative Fuel for Diesel Combustion Engines
Michna, Lukáš ; Novotný, Pavel (referee) ; Stodola, Jiří (advisor)
In the introduction this thesis brings a short summary of the energy, environmental and economical balance, related to the production and use of conventional fuels for diesel engines, and compares them with possibility of using recycled cooking vegetable oils as a fuel. The main part focuses on the laboratory analysis of major physical and chemical properties of this alternative fuel and on their comparison to diesel fuel, especially according to ČSN EN 590 norm. In conclusion there is a proposal of diesel vehicle modification to be propelled with waste vegetable oils.

Seal Plugs Design for Common-Rail System Pressure Reservoir High-Cyclic Fatigue Testing
Skrutek, Ivo ; Cupl, Zdeněk (referee) ; Ramík, Pavel (advisor)
Tato diplomová práce je zaměřena na řešení problému praskání těsnících kuželů na tělesech railů při zkoušce dlouhodobé životnosti pomocí pulzního vysokotlakého testu. Hlavní částí je analýza vlivu těsnících zátek na namáhání těsnícího kuželu s následným návrhem nové zátky, která bude tvořit stejné nebo podobné zatížení všech komponent při pulzním testu jako vysokotlaká trubka, která se používá v sériové produkci. Další částí je ověření vlastností nové zátky pomocí vysokotlakého pulzního testu.

Design of yard locomotive
Miklica, Martin ; Pelikán, František (referee) ; Křenek, Ladislav (advisor)
Plenty of designing works focused on railway technology were made through the time. But the majority of them are concerned with high-speed trains or at least express train locomotives, but works devoted to design freight or shunting locomotives can be barely found. This diploma thesis is looking into nearly unexplored territory and finding out, which possibilities in the design of shunting locomotives of independent traction do exist, and find better solutions then those currently used, where possible and appropriate. The result of this master thesis work is design of shunting locomotive, which respects the requirements of railway standards, ergonomics and safety, and still brings in modern design solutions.

Remotorization of the aircraft EV-55 Outback
Puller, Tomáš ; Weis, Martin (referee) ; Horák, Marek (advisor)
Thesis Remotorization of the aircraft EV-55 Outback deals with possibility of installationt piston diesel engine instead of turboprop engine PT6A-21. Begining of this thesis deals with choice of convenient engine and propeller. Then, 3D model of engine bed is designed, followed by mass analysis. Based on results from the mass analysis and requirements from the CS - 23 regulation, load is specified and stress analysis is done. The other part of this thesis deals with adjustment of the airframe and with calculation of flight performances. Finally, economic indices are specified.

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.

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.

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.
