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.

OSD data system design of small transport aircraft for training of maintenance personnel
Plačková, Veronika ; Jiří, Duda (referee) ; Koštial, Rostislav (advisor)
This master’s thesis describes the area of operational suitability data that is established as part of the aircraft type certificate. The thesis first chapters are describing OSD, its origin and implementation. The thesis also analyzes all regulations that are connected with this matter and are focusing on the training of maintenance certifying staff. A part of this thesis deals with the description of aircraft Evektor EV-55 Outback, for which is created the educational material, and a description of its fuel system. The concept of educational material for maintenance certifying staff theoretical type rating training and an example of final test are at the end of the thesis.

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.

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.

Evolution of the Tatra Diesel Engines
Paulmichl, Roman ; Vančura, Jan (referee) ; Svída, David (advisor)
The bachelor thesis deals with the development of diesel engine TATRA from their inception to the present. It focuse on the construction of engines and construction of the disparity of their development. Gives an overview of their own construction of engines and their technical solutions. Compares the structural design of each engine in a chronological sequence of their formation and subsequent production. Informs on the composition and function of individual systems engines, changes in their composition and modernization. Provides examples of differences in the various engine components. Creating insight on the issue of engine construction as a whole and each of its systems and subsequent comparison of the impact of engines on the environment. Explains the basic concepts from the construction of diesel engines and their components. The theses target is to provide an overview of construction solutions of TATRA engines, depending on the time of their inception and requirements for diesel engines today.

Design of Diagnostic System for Small Transport Aircraft
Harasim, Tomáš ; Bencalík, Karol (referee) ; Třetina, Karel (advisor)
Due to the airliners and aircraft operators pressure on reducing the operating costs, the diagnostic systems are included in aircraft, so that the wearness of single functional elements of other functional systems can be monitored. This monitoring can save money, that are usually spent on maintenance and especially, it leads to an increase of the overall safety of aircraft operations. The task of this work is to design a diagnostic system for small transport aircraft. For the right and proper design, is the correct understanding of the functions of each part on aircraft systems needed. The part of this work is attended to the selection procedure of appropriate diagnostic parameters, next section deals with the suitable options of their scanning. I do mention the summary of the chosen diagnostic parameters for the scanning and the recomended ways of their measuring.
