Analysis transport system in primary agricultural production
Raška, Michal ; Kubín, Karel (referee) ; Kašpárek, Jaroslav (advisor)
This thesis presents a comparison of fuel consumption and transportation efficiency of various transport vehicles in primary agricultural production. The first part deals with the possibility of transport of materials in agriculture. The following is a description of the compared vehicles. Finally, it describes the methodology of calculation of fuel consumption vehicles, which are then compared.

Aero Engines for Aircraft up to 2000 kg
Loutocký, Jiří ; Šplíchal, Miroslav (referee) ; Juračka, Jaroslav (advisor)
This bachelor project was created like database of certified aircraft engines for aircraft with 450 - 2000 kg of weight. It is divide into four parts. Each part contains another conception of comparison. First part comprises of list of worldwide successful manufacturers and their products. Second part ranks engines by type of fuel transfer to combustion chamber and charge pressure. Third part compares engines with similar power in tables and in graphs. (Class 100, 200 and 300 horse power). Last part solves selection of most optimal engine in classes 100, 200 and 300 horse power.

iOS Application for Driving Data Extraction and Analysis via OBD-II
Pihrt, Patrik ; Beran, Vítězslav (referee) ; Bobák, Petr (advisor)
This project aims to create a mobile application for iOS devices that provide valuable information about user's car rides. Needed data are obtained by ELM327 located in OBD-II scanner which can communicate with the car. Obtained data are analyzed using table of limits. The application informs riders about their driving mistakes and giving them tips how to fix them. Trips can be saved and exported in the form of logbook. In addition application includes diagnostic functions that can be found in every other diagnostic application.

Mathematical Modelling of Vehicle Fuel Consumption
Dražka, Jan ; Novotný, Jan (referee) ; Popela, Pavel (advisor)
This bachelor’s thesis deals with a model building of vehlicle’s model based on real data and with a modelling of it’s movement and it’s fuel consumption. The thesis includes a preparation of input data as well as model building. The main aim of the thesis is the comparison among selected driving modes from the point of fuel consumption and it’s optimization. This comparison is simulated in MATLAB environement and GAMS with the use of selected optimization algorithms.

Computational Study of the Miller Cycle on a Gasoline Engine with a Turbocharger
Černý, Roman ; Janoušek, Michal (referee) ; Vondrák, Adam (advisor)
The scope of this thesis is the Miller engine cycle analysis and its practical application on a turbocharged spark ignited engine. Based on the sensitivity analysis of the limits affecting the ideal Miller cycle thermal efficiency a thermodynamic model of the engine with a prolonged expansion was set up in the GT-POWER software. The results of the analyses were used to evaluate the feasibility of the reference engine conversion for an operation with Miller cycle.

Overview of means for reducing induced drag
Mazánek, Adam ; Švec, Michal (referee) ; Daněk, Vladimír (advisor)
This bachelor thesis deals with the creation of overview of means for reducing induced drag on the wing of an airplane. It describes production of the induced drag and how it changes during a flight. The bachelor thesis also deals with geometrical modifications of the wing. The most extensive part is devoted to structural modifications of wing tips with special aiming on winglets.

Cooler Test Bench
Kleger, Ondřej ; Smejkal, Michal (referee) ; Ramík, Pavel (advisor)
Emission limits and economic situation pressure automobile manufacturer, over the prospective buyer, to production more economy car. One of the elements which may indirectly reduce for example fuel consumption is automobile radiator. Construction of these accessories isn’t simple and simulation its characteristics need inspection in real measurements. Test bench for automobile radiator can help to easily choice and the project cooling system of the vehicles.

Effect of engine load on the output parameters of the tractor kits
Paulmichl, Roman ; Svída, David (referee) ; Bauer, František (advisor)
The thesis deals with the current situation in the construction of tractors, particularly engines and accessories. The work includes a methodology for measuring tractor rigs in traffic as well as methodology for plough/plow kits measuring. The measured values were tabulated, graphically presented and analysed. The thesis provides an overview of the issue of the combustion engine load placed on the engine by working conditions in transport, during primary soil tillage with different modes of operation of the tractor set. The thesis aim is to find out the practical effect of the engine load on the monitored parameters and to indicate possibilities for achieving higher efficiency in tractor units with minimum fuel performance
