Construction of On-board Computer for Motorcycle
Rulc, Martin ; Široký, Daniel (referee) ; Šteffan, Pavel (advisor)
This work deal with system design and implement of Trip computer for motorcycle serving as information element of speed and fuel consumption motorcycle. The general aim is design of device with graphic display that shall represent measured values of speed motorcycle, rpm of motor, onboard voltage, charging current, motor temperature and ambient temperature. All measuring data will be saving on memory card. For easily tracking in system menu will be used touch panel on graphic display.

Proposal heating system of the house
Taclík, Jakub ; Štelcl, Otakar (referee) ; Baláš, Marek (advisor)
This thesis is focused on computation of family house heat losses with two floors above ground, choice of three heat sources, and designing of radiators to cover the losses. The thesis also contains computation of a fuel consumption for a heating period and a discussion which one of heat sources, with particular temperature gradient, is the most economic.

Minimization of the car fuel consumption on the route elevation profile
Srba, Jan ; Klimeš, Lubomír (referee) ; Mauder, Tomáš (advisor)
This thesis deals with mathematical modelling of the fuel consumption of a vehicle going on the route described by its elevation profile. It contains fundamentals of vehicle longitudinal dynamics which are essential for creating the model. The main goal of this thesis is to minimize the fuel consumption on given route using heuristic algorithms, hence a description of used heuristic algorithms and results of their implementation in MATLAB are presented.

Proposal of driveline of prototype for Shell Eco-marathon
Skácelík, Radek ; Klimeš, Lubomír (referee) ; Štětina, Josef (advisor)
In the bachelor thesis, the drivetrain design of the racing car is solved and described. The competition rules are summarized in the introduction. Then the driving resistances and drivetrain design variants are evaluated, which main objective is to achieve low fuel consumption. The solution is focused on the concept of a planetary gear-shifting hub, in combination with the synchronous belt drive. The Honda GX25 engine with a centrifugal clutch and the driven wheel dimension of 20” is used to drive the design. The design solution is shown at the assembly drawing.

Fuel additives for modern internal combustion engines
Mach, Petr ; Kaplan, Zdeněk (referee) ; Píštěk, Václav (advisor)
This bachelor thesis is devoted to thorough research of fuel additives, especially their effect on deposits in internal combustion engines, wear and service life of the engines and their effect on fuel consumption. The first chapter briefly informs about automotive fuels and explains the used terms in this work. The next chapter describes the types of fuel additives and their use. The third chapter deals with the deposits in the internal combustion engines and their reduction using detergent additives. The fourth chapter focuses on the types of wear and places where arise. This chapter also aims to prove the positive effect of additives on the engine components service life. The last chapter focuses on the fuel consumption and importance of additives in world fuel consumption.

Launching and Operating Issues of Supersonic Business Jet
Kincová, Daniela ; Veselý, Petr (referee) ; Šošovička, Róbert (advisor)
Tato práce se zabývá problematikou zavedení a provozu nadzvukových business jetů. V dnešní době se v civilní letecké přepravě, po ukončení provozu Concordu, žádná nadzvuková letadla nevyskytují. V dnešní době existuje mnoho projektů a organizací, které se zabývají znovuzavedením nadzvukových letounů do civilního letectví a soustředí se převážně na business jety. Hlavní otázkou je, zda je vůbec vhodné, či rozumné se k tomu typu dopravy znovu vracet. Existuje hodně problémů, které toto komplikují. Tyto letouny způsobují příliš velký hluk, mají obrovskou spotřebu paliva a musí řešit nadměrné emise, létají ve vysokých výškách ve kterých může docházet k problémům s přetlakováním kabiny, navigací, radioaktivním zářením apod. Navíc zákaz supersonických letů nad pevninou letové cesty omezuje a prodlužuje. Současně vznikající projekty navíc nedosahují tak velkého doletu jako klasické moderní bussjety, což způsobuje, že se nadzvukové business jety se na delších tratích stávají neefektivní. I přes tyto problémy, je víceméně jisté, že k zavedení nadzvukových business jetů dojde během následujících 10 - 15 let, i kdyby to měla být jen otázka jisté prestiže velmi bohatých lidí.
