Non-traditional Motorcycle Conception
Brezanský, Vít ; Drápal, Lubomír (referee) ; Beran, Martin (advisor)
The goal of the thesis is to introduce some interesting and non-traditional conceptions of motorcycles from the present and also from previous years. In every part reasons are described that led producers of these motorcycles to design conceptions that might be perceived as almost absurd. However not every one of them was forgotten and some succeeded on the roads and race tracks, others will be perhaps successful in a few years. Every part also includes a description of the construction and function followed by the assessment of individual solutions according to their justification, realization, number of pieces sold or race results.

Passenger Vehicles Drive Unit Recent Development
Korenko, Miroslav ; Drápal, Lubomír (referee) ; Beran, Martin (advisor)
The aim of this bachelor's thesis is to cover current trends in development of propulsive units of personal automobiles. The introduction describes combustion engines and divides them into categories. The next chapters describe current development of gasoline and diesel combustion engines. The conclusion is aimed for the perspective view into the future and the problem of alternative propulsions.

Automotive Diagnostic Systems
Bůžek, Václav ; Beran, Martin (referee) ; Ramík, Pavel (advisor)
This thesis is written to make a review abstracting of contemporary systems of automotive diagnostics. It is aimed at the principles of serial and parallel diagnostics and informs about contemporary norms. It brings nearer the basics of used on-board diagnostic systems, including the diagnostics of its components. The thesis also exemplifies the practical functions and possibilities on the elementary diagnosing by using the diagnostic software SuperVag.

Software for Optimalization of Gear Speed
Pokorný, Pavel ; Beran, Martin (referee) ; Svída, David (advisor)
Rolling vehicle is being influenced both by driver and many other factors of physical nature. These factors affect the whole behavior of the car, its performance, fuel consumption etc. It is very reasonable to cope with these factors then. The main aim during vehicle evolution (both civil and racing ones) is to optimize the influence of all invisible enemies as much as possible. The aim of this work is a description of factors influencing the moving vehicle. Several practical examples are included. The theory of transmissions is fundamental to the programme for creating a saw-diagram and gear speed optimization. Finally a few analysis of the real vehicles and subsequent evaluation will be done. The output of the work is an overview of factors affecting the moving vehicle, the results of performed analysis and programme for optimization of gear speed.

Electronic control units of present SI-engines
Michna, Lukáš ; Beran, Martin (referee) ; Dundálek, Radim (advisor)
Bachelor’s thesis named „Electronic control units of present SI-engines” treats of presently known and extended electronic control systems of SI-engines, so those ones, who mainly control both fuel-air mixture preparing and its ignition in combustion chamber. These are two fundamental functions for engine running, so they are described in light of basic principle of operation and also in light of each kind of these systems and its developmental stage description. Next point is enumeration and description of single parts of electronic control system participating in engine controlling, separated to logic sections. The end of publication makes reader acquainted with most extended types of electronic control systems, their producers and elementary differences.

Overcharginh of SI and CI Engines
Čavoj, Ondřej ; Beran, Martin (referee) ; Dundálek, Radim (advisor)
This Bachelor’s thesis is focused on overcharging and its influence on spark-ignition and diesel engines. It describes common overcharging methods, including their advantages and disadvantages. In analysing the most regular of them, it also mentions their design elements and possibilities of eliminating some of their weak points. It also contains short summary of this segment’s history, the view on possible future development and at the end even examples of overcharged engines.

Systems energy recovery for personal and sports vehicles
Marada, Ondřej ; Zháňal, Lubor (referee) ; Beran, Martin (advisor)
This bachelor thesis is dealing with methods to decrease energetic and ecological load of cars. In particular, it follows kinetic energy recovery systems (KERS). The thesis summarizes the types of KERS, their building elements, i. e. the establishment for accumulation of energy and its transmission. Then the survey of known fulfilments KERS follows and in the conclusion it is dealing with their contribution to the use of sport and personal motor cars.
