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.

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.

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.

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.

Vliv připojení nesených strojů v tříbodovém závěsu na výstupní parametry traktorových souprav
Kopecký, Petr
In the literary part of the diploma thesis, a brief overview of the current state in the tractor design has been done, concentrating onto such elements that lead to lowering of fuel consumption. The practical part is based on the realized solution. The target of the measurement was to prove the influence of adjusting of the three-point hitch onto the output parameters of ploughing sets, consisting of the Zetor Forterra 140 HSX tractor and Kverneland 150 B mounted plough or Kverneland PN 100 semi-mounted plough. The essence of the measurement was gradual shortening of the upper linkage of the three-point hitch, whereas simultaneously with shortening of the linkage, the force on the linkage was rising. The force was measured by means of strain gauge Hotinger U2A. In case of the mounted plough it has been proved that shortening of the upper linkage causes rising of the force. That shifts part of the plough weight onto the rear wheels of the tractor, resulting in lower wheel slipping and lower fuel consumption.

Technicko-ekonomické hodnocení traktorových dopravních souprav
Vacek, Pavel
This thesis deals with the technical and economic evaluation of tractor transport kits. The first part is indicated the current situation in construction of tractors and there is, more detailed description of structural elements of tractors NewHolland T7050 PowerCommand and AutoCommand. In the second part there is the methodology of laboratory measurements and their subsequent evaluation. The third part deals with the field measurements, where is described the detailed profile of the test track and measurement methodology. At the end the measured data were given into the tabular and graphical form and finally evaluated. The evaluation of the data shows that the transmission is suitable for transports. The thesis came to the conclusion about which kit had the best results according the conditions.
