Valve train of modern internal combustion engines
Pohořelský, Petr ; Klimeš, Lubomír (referee) ; Píštěk, Václav (advisor)
In my bachelor's thesis I was concentrated on a principle of an activity, which is related to timing mechanisms of modern combustion engines, with a focus on variable valve timing. The thesis is conceived as a research of available electronic resources, professional literature and articles from professional periodicals. In the thesis there are introduced the principle, description of the activity and a brief history of combustion engines. The main part is focused on a specification, which is related to variable valve timing, and a summary of systems, which are used in today´s modern vehicles.The conclusion contains a critical evaluation, in which there are written advantages and disadvantages of this problem.

Power Increasing of Serial Combustion Engines
Novák, Pavel ; Svída, David (referee) ; Dundálek, Radim (advisor)
In this bachelor’s thesis is presented suvey of technical resolution for power increasing of serial combustion engines. The work is oriented especially on technical resolution for spark ignition engine and diesel engine. First two chapters says obout way of combustion process and obout creation the fuel mixture of spark ignition engine and diesel engine. In other chapters is described change length of suck pipeline, mechanical and turbo boosting engine and variable valve timing which is depended on the engine load. At the close there is short muse obout future in tecnical development.

Methods of reducing the consumption of modern vehicles
Kubeš, Filip ; Pech, Ondřej (referee) ; Štětina, Josef (advisor)
This thesis summarizes the basic knowledge of thermodynamics of internal combustion engines. Emphasis was put on engine efficiency and engine cycles, described by theoretical and indicator diagrams. It also introduces classification of engine efficiencies, and their respective definitions. The next section focuses on some systems used in modern vehicles, that improves engine efficiency and reduces fuel consumption. Moreover it includes conceptual solutions, that are in preparation for mass production. The last part of this thesis concentrates on economical driving techniques, and reduction of driving resistance. In conclusion, the thesis shows the direction of next development of automobiles.

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.

Passenger Vehicles Drive Unit Recent Development
Sedlář, Martin ; Svída, David (referee) ; Beran, Martin (advisor)
This bachelor’s thesis is an overview of modern drive units trends. The first part of this thesis demonstrates combusting engines sorting; the next main part is an overview of a few drive units which are characteristic for their categories. There is a comparison of two lower power class engine representatives and two higher power class representatives in final chapter. The conclusion summarizes described topic and expresses own opinion.

Selected modern trends in internal combustion engines
REJTHAR, Jakub
This bachelor thesis focuses on combustion engines especially on four-stroke spark-ignition engines and their current modern trends such as downsizing, variable valve timing, start-stop system, hybrid and hydrogen drive in the automotive industry. The first part of the thesis is a brief description of the history of combustion engines, their basic distribution and key parts which the engine is designed together with a cooling, electric and suction system from. The second part describes modern trends, their use and subsequent application in passenger cars.
