Automotive differentials
Holeňa, Vít ; Píštěk, Václav (referee) ; Kaplan, Zdeněk (advisor)
This bachelor thesis is about automotive differentials. The aim of thesis was to create an overview of various types of differentials, primarily self-locking. First chapter is dedicated to transmission of which the differential is a part of. Second chapter is about differential function in general. In third chapter, attention is paid to self-locking differentials, especially to Torsen differentials. Last of all, fourth chapter is about active differentials and systems, which help us to overcome disadvantages of differentials mentioned above.

Three-cylinder engines for small passenger cars
Nárovec, Jiří ; Kaplan, Zdeněk (referee) ; Píštěk, Václav (advisor)
The aim of this bachelor’s thesis is to gather information about three-cylinder combustion engines used in small passenger cars nowadays. The thesis is conceived as a search of available electronic sources, company literature and specialized journal articles and involves fundamental technical-economic parameters of 15 selected types of three-cylinder engines. It contains the comparison of three-cylinder gasoline engines using the method of decision analysis and the prognosis of future development and application of such engine unit concept in small passenger cars.

Bioetanol and Drive of Automobile
Smeták, Pavel ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
Content of my diploma thesis focuses on identification of properties and usability of nascent fuel for automotive use. It is a bio-ethanol which can be produced from renewable sources. The heart of this work is to develop methodology of experimental trials in connection with utilization of bio-ethanol E85 as a fuel for vehicle combustion engines. The aim is to perform tests with E85 and BA95 fuels in engine testing room of ÚADI FSI, to compare these trials amongst themselves and to analyze obtained results. Subsequent part of diploma thesis covers overview of general usage of bio-ethanol in road transportation.

Stirling engine 3kW combustion chamber
Matuška, Petr ; Zháňal, Lubor (referee) ; Kaplan, Zdeněk (advisor)
This thesis deals with the construction proposal of the combustion chamber of Stirling engine. The introduction briefly describes the history and practical application of Stirlinova engine today. The following section explains the differences between theoretical and real cycle and the principle of beta Stirling engine modifications. The next section is devoted to the calculation of fuel and air consumption and fuel compared to each other. The proposed design is based not only on the calculation of fuel and air, but also heat transfer between flue gas and preheated air. The last part is devoted to calculating the flow of LPG and flow model of the combustion chamber.

Six-cylinder in-line diesel engine with cylinder deactivation
Novosád, Ivan ; Kaplan, Zdeněk (referee) ; Píštěk, Václav (advisor)
Master 's thesis deals with design of a drivetrain of six cylinder inline engine with cylinder deactivation for heavy agricultural vehicles. In this thesis were devised various possibilities of crankshaft balancing, the best design solution of counterweight was based on optimization in software Catia. Further, the crankshaft was analysed for force and momentum loading and torsional vibration, based on which, the torsional vibration damper was designed. There were considered several options for cylinder deactivation, which were analysed for finest run of engine and the best thermal distribution. Based on these criteria, the best option was to deactivate 2nd and 5th cylinder. The crankshaft was analysed for the fatigue failure by finite element method. The fatigue failure is the most dangerous case for the crankshaft, the resulting safety factor for this limit state is 3,05.

Ideal cycles of combustion engines
Kertész, Tibor ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
The main subject of this bachelor´s thesis is to summarize basic theoretical knowledge of ideal thermodynamic cycles and to develop their mathematical models in Matlab to calculate and draw diagrams of each cycle. Based on the calculated values, it was possible to compare the cycles with each other.

Vehicle Kinematics and Dynamics Simulations
Zháňal, Lubor ; Bauer, František (referee) ; Píštěk, Václav (referee) ; Kaplan, Zdeněk (advisor)
This paper focuses on the kinematic and dynamic numerical simulation of mechanisms by applying a numerical method, and a complex simulation programme built on it, developed by the author. Described are mathematical principles of the numerical method used and also the programming progression of the important parts of the application and its optimization. The final part includes comparative measuring of the accuracy and performance.
