BMW Twelve-cylinder Engines
Macek, Libor ; Janoušek, Michal (referee) ; Drápal, Lubomír (advisor)
Bachelor’s thesis deals with mapping manufacture of BMW twelve-cylinder engines in accordance with current legislation. Thesis described the issue of engine construction and materials with respect to current requirements. Beginning of bachelor’s thesis is dedicated to the history od the BMW brand, especially to founders, first made vehicles and iconic vehicles. Carmaker has celebrated 25 years anniversary of V12 engines in 2012. Third chapter is dedicated to engine marking, because engine marking is difficult to understand. The next chapter is the most comprehensive because it contains a list of engines, including their description and comparison with the competition. In addition to passenger vehicles is thesis briefly focused on sport cars engines and prototypes that were never been mass-produced. The last chapter is devoted to the used technique, primarily to variable valve timing and variable valve lift . Furthermore, it aims to High Precison Injection, Electronic throttle control valves , CAN-Bus and marginally also TwinPower Turbo. In conclusion of the thesis is list of sources, tables and pictures of all engines and pictures explaining used techniques.

Vehicle response when using the Start-Stop system
Vaňková, Denisa ; Kohout, Tomáš (referee) ; Jelínek, David (advisor)
The diploma thesis deals with the research of vehicle response in case of using the Start-Stop system in passenger cars with manual and automatic transmission. Values measured using CAN-bus connection of the drivers using Start-Stop system are compared with values from identical vehicles without using the Start-Stop function. A device designed specifically for the purpose of these measurements is used as the control element of the measurements, operating on the basis of a wheel rotating uniformly with the movement of the vehicle and an optical sensor which detects the movement. The measured results are intended to demonstrate the response time of the vehicle using the start-stop function and to determine whether this system has an effect on the starting delay in normal traffic. By using CAN-bus data measurements, detailed start-up graphs are available for all the vehicles studied. The study found that it depends on the type of gearbox used in the vehicle, while with a manual gearbox, Start-Stop does not have a large impact on the flow of traffic in terms of the vehicle's response to the driver. For automatic transmission, it depends on its type, and the differences between individual starts, with the Start-Stop system on and off, differed considerably. The accuracy of the measurement was similar for both measuring devices, but the CAN-bus measurement is more useful, as it is possible to determine the exact course of the start from the obtained data. The manufactured measuring device is easier to operate and the evaluation of the run-up length is done automatically, immediately after the run-up. Based on this work, more extensive research can be carried out in the future, the purpose of which could be to categorize the run-off lengths by individual vehicles, which is particularly important for the purposes of accident analysis.
