Petrol Direct Injection
Moravec, Tomáš ; Janoušek, Michal (referee) ; Dundálek, Radim (advisor)
This bachelor thesis is about the system of direct injection petrol engines within cars. The first chapter is designated to the history of the direct injection petrol system and the development of different concepts. The thesis then concentrates on the mixing of air with fuel and describes the injection system in detail. Within the content of my work is a list of specific engines, using the direct injection system. The last chapter is devoted to the future development of direct injection petrol system and those with the compression-ignition system.

Formula Car Fuel System Design
Rubíček, Pavel ; Svída, David (referee) ; Ramík, Pavel (advisor)
The fuel system is a very important part of the vehicle and the engine. The main function is to deliver the fuel- air mixture into the engine cylinder. This thesis describes the design of the Formula student car fuel system. The first part is an introduction to Formula Student competitions. The next section describes the options of the fuel systems structure and options for individual components. Those rules limit the possibilities for us FSAE that in the next chapter. The following parts are major chapters dealing with the actual design of the fuel system and analysis of selected components. The last part are chapters that deal with the production possibilities of parts and subsequent incorporation into the fuel system of the car.

Up-to-date Supercharged Petrol Engines
Gruber, Jakub ; Janoušek, Michal (referee) ; Dundálek, Radim (advisor)
This bachelor thesis is focused on the modern supercharged petrol engines. The intro-duction opens with a brief overview of the European emission standards. The main part of the work deals with the devices reducing car emissions. There are described fuel sys-tems and specific components of a direct fuel injection. A vast part of the work is dedi-cated to the downsizing of the engines and its contribution. I also mentioned the alter-native fuel vehicles.

Improving Performance of Turbocharged CNG Engine
Janoušek, Michal ; Beran, Martin (referee) ; Svída, David (advisor)
The aim of diploma thesis is the design of fuel system for the Caterpillar twelve cylinder spark ignited turbocharged engine. The fuel system is designed for sequential electronic controlled gas injection into intake manifold. Computational model of the engine was calculated in Lotus Engine simulation software. CFD analysis of mixing CNG with air was computed in Star CCM+ software.

Combustion Engines with Gasoline Direct Injection
Schulla, Radek ; Řehák, Kamil (referee) ; Dundálek, Radim (advisor)
This bachelor thesis deals with the problematics of direct gasoline injection in petrol engines. It presents basic overview of pollutants from exhaust gases, functions of individual components of fuel system and their development. Next chapter explains the principle of operation, advantages and disadvantages compared to port fuel injection. The last section is focused on use of direct injection in the future.

Installation of the LYCOMING power unit into the Bristel UL aircraft
Kročil, Petr ; Juračka, Jaroslav (referee) ; Píštěk, Antonín (advisor)
This diploma thesis focuses on Lycoming drive unit mounting used in two-seater plane of VLA category (the very light aircraft). In the beginning characteristics of currently produced Bristell aircrafts are described. Following chapters aim at research selection of new drive unit mounting based on multi-criteria decision analysis. For selected unit, the weight, center of mass and flight performance are calculated. Additionally, the construction of engine mount is proposed. According to CS-VLA and CS-23 stress level of mounting is defined followed by strength verification. Later in this thesis, a suitable engine cover for engine and cockpit cooling is proposed. A complete fuel system is described in following chapter. Last chapter deals with financial costs of re-engining as well as aircraft operational costs.

Gasoline Direct Injection
Smejkal, Jan ; Janoušek, Michal (referee) ; Dundálek, Radim (advisor)
This bachelor thesis deals with the problematics of gasoline direct injection in combustion engines. There is a view of the history of the development of gasoline direct injection in the introduction. The main part focuses on the principle of the process function, description of components of fuel system and specific components of exhaust system. There is also a description of benefits of using gasoline direct injection, especially considering the amount of pollutants in exhaust gas. The following part of the work contains an overview of gasoline direct injection engines and their comparison in terms of power. In the conclusion, there is a consideration of gasoline direct injection development in the 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.
