Motorcycle rotary engine
Novotný, Petr ; Rozsíval, Jan (referee) ; Zháňal, Lubor (advisor)
Diploma thesis is focused on conceptual design of Wankel rotary engine with performance between 30-60 kW. Performance of designed engine is determined to 35 kW and volume of one chamber amounts to 245,58 cm^3. In this thesis are step by step calculated geometrical properties of each design group which are afterwards put into 3D data. There is also solved cooling system of designed engine and design of geometrical and characteristic properties of parts of cooling system. Last but, not least there is solved placement of designed engine into frame of motorcycle. As suitable motorcycle has been chosen Honda CBR125R because it has very advantageous layout of frame.

The pistons of four-stroke engines and their application
Jelínek, David ; Fojtášek, Jan (referee) ; Dlugoš, Jozef (advisor)
This thesis deals with historical development of pistons for four-stroke combustion engines and their application for machines using both diesel and petrol fuel. The beginning explains how the four-stroke combustion engines works and what role the piston plays that. The following is about the description of the individual parts of the piston, the important attribute the piston should have and how the piston is loaded by the forces in the combustion process. The next part deals with the historical development of the piston, especially in the first half of the 20th century, when the combustion engines had the greatest rise. In this chapter are summarized the design methods, the types of material and the Wankel engine. Below is a summary of the modern methods of producing pistons, their types of use, types of materials, coatings and cooling methods.

The special piston engines on the general aviation aircraft
Motyčka, Ivo ; Zablatzký, Jiří (referee) ; Imriš, Pavel (advisor)
Topic of this bachelors thesis are Special piston engines on the general aviation aircraft. In the first part, the historical development is adumbrate and their operating principle. Next part deals with particular special piston engines, expansion, advantages and disadvantages, principles and their impact for general aviation. There are impeaching demands of JAR-FCL 1 rules in certification of engines. Next part is being paid to operating conditions of aeroplanes. At last the confrontation between special piston engines and most used engines of general aviation is made.

Comparison of traditional and nontraditional cycles of heat engines
Dobiáš, Ladislav ; Jedelský, Jan (referee) ; Štětina, Josef (advisor)
The bachelor thesis describes the thermodynamic cycles of four-stroke spark ignition (SI) and compression ignition (CI) engine, Wankel engine and two-stroke spark ignition (SI) engine. Based on the information is compared with thermal efficiency of each engines with four-stroke spark ignition engine in the T-S diagrams. There were also dedicated to Atkinson cycle and its use in practice. The last part deals with the construction of a variable compression ratio used in the development of modern engines.

3D model Wanklova rotačního motoru pro výuku technických předmětů
BAŠTÝŘ, Jan
The bachelor thesis deals with the technique of 3D printing and materials suitable for its printing is currently widespread. The theoretical part of the work is focused on the history of 3D printers, a description of selected 3D printers and their comparison, and finally contains an overview of selected materials suitable for use in printing 3D models. The practical part deals with the use of 3D printing for the needs of teaching technical subjects. Within this work, a scale model of Wankel's engine is created for use in teaching.
