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.

Direct injection systems for spark-ignition engines
Vondráček, Václav ; Rasch, František (referee) ; Drápal, Lubomír (advisor)
This bacheleor´s thesis deals with direct injection of fuel spark-ignition motors. In each chapter you can learn about principle activities injection of fuel, meet single parts and components and learn how these components work. Further, this work compare some constructional differencies of the systems of some automobile producers and observes contemporary general way of those problems with reference to future.

Fuel Systems of SI-engines
Faiman, Jiří ; Drápal, Lubomír (referee) ; Dundálek, Radim (advisor)
The aim of this work is to create a list of fuel systems used in modern gasoline engines and describe the basic components of these systems. It will then be described the function of each of these components and modes of operation of the fuel system at different modes of engine operation. Finally, will be characterized by the selected engines with these systems.

Internal combustion engine for Mars and Moon vehicles
Rachůnek, Radek ; Beran, Martin (referee) ; Svída, David (advisor)
The thesis deals with the development of a mathematical model of the internal combustion engine for vehicles used in space missions. It includes a summary of the historical development and the possible future of the vehicles. It describes the external influences acting on the engine, summarizes the advantages and disadvantages of using an internal combustion engine. A separate chapter focuses on fuel selection with respect to the availability of local resources. The next part of the thesis is devoted to the development of a mathematical model according to a sample real engine. Here, the step-by-step process of modifications to create the engine model is described, considering the information from the previous chapters. The thesis includes an evaluation of the internal combustion engine to see if it represents a suitable alternative to current powertrains.

Equipment for analysis of fuel jet from fuel nozzle
Krahulík, Michal ; Beran, Martin (referee) ; Svída, David (advisor)
Aim of this diploma thesis is a design and realization of the test rig for measuring characteristics of fuel jet from injector nozzle for vehicle internal combustion engines. The test rig was designed to test injectors for direct injection of petrol engines, especially for 1,5 TSI engine, which can be found in Volkswagen Group cars. The construction allows testing a big variety of injectors with only small adjustments of the test rig. Design was created in software Solidworks 2020. The thesis also deals with production process of individual components and with description of the used components for measuring and controling the test rig.
