Apex Seal for Wankel Engine
Böhm, Michael ; Ramík, Pavel (referee) ; Svída, David (advisor)
The master’s thesis deals with analysis of sealing elements of Wankel engines and their design. The necessary steps for creation of the model of dynamics of apex seal are provided, whereby the resulting force loads are then obtained. Furthermore, the design of the apex seal spring, the choice of the material and the production jigs for the production of the spring itself are presented. The finished components are tested in the engine testing laboratory and the results evaluated.
Motorcycle rotary engine
Slíva, Jakub ; Dlugoš, Jozef (referee) ; Zháňal, Lubor (advisor)
This master's thesis describes a concept of Wankel type rotary engine for use in motorcycle with estimated power between 70 – 80 kW. Basic geometry parameters of rotor and ports are calculated. Power output is then checked on equivalent piston combustion engine with central crank mechanism in 1D simulation model. Rotor is designed for use with oil cooling system. Rotor is checked for safe design by static FEM analysis by applying maximum pressure found out of 1D simulation model.
Thermodynamic model of Wankel engine with output power 11 kW
Drbal, Milan ; Beran, Martin (referee) ; Svída, David (advisor)
The master’s thesis deals with the Wankel rotary engines and their 1D simulations using a thermodynamic simulation software for the piston engines. The necessary steps for creation of the equivalent model of the four-stroke three-cylinder combustion engine are provided. The engine used for the validation model was Aixro XR 50. The data measured on this engine during testing were used to validate the created thermodynamic model. The discharge coefficient calculation of the intake and the exhaust ports is shown. The 11kW engine design is created using validated thermodynamic model.
Design of LPG-Powered Portable Generator for Resealable Cartridge
Vevera, Tomáš ; Křenek, Ladislav (referee) ; Sovják, Richard (advisor)
The topic of this bachelors thesis is the design of LPG powered generátor for resealable cartridges. The main goal is to design a lightweight portable power source. This goal has been achieved by using a rotary engine.Adding a power bank into the generátor has reached a wide use potenciál. The final design accomplishes all ergonomic and functional requirements. The final shaping tries to adress the potenciál users.

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.
Variable geometry of intake and exhaust ports of Wankel engine
Krejčí, Tomáš ; Beran, Martin (referee) ; Zháňal, Lubor (advisor)
The purpose of this thesis is to design the key parameters of the high-powered Walkel engine and to design a chamber side on the base of computed parameters so that it enables variable change of the intake and exhaust port geometry. Consequently, to carry out a flow simulation in both ports in designed chamber side in order to find out its flow character and geometry change reaction.
Powertrain of racing Wankel rotary combustion engine.
Blažo, Marek ; Blaťák, Ondřej (referee) ; Zháňal, Lubor (advisor)
The main aim of master’s thesis was to handle the computing proposal and the construction design of the powertrain of racing Wankel rotary engine with 300 kW power output and in the case of 9000 speed per minute. On the basic of these values was made the primary design of the rotary engine, design of the eccentric shaft and rotor housing. Mechanical stress and torsional vibrations of the eccentric shaft were analyzed by using the course of indicator diagram.
