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.

Experimental Car Formula Faster Rebuild
Zarambukas, Michalis ; Zháňal, Lubor (referee) ; Blaťák, Ondřej (advisor)
The main purpose of this diploma thesis is the experimental vehicle Formula Faster engine reconstruction. The current Ford Kent 1600cc engine will be replace by the Škoda 1.4 MPI engine. The next task is to analyse kinematic properties of the front axle and subsequent optimization and transformation of steering rod placing which relates to wheel toe and bump travel. The last part is concerned with steering wheel mounting transformation, concretely with reconstruction to obtain removable steering wheel using rapid coupling.

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.

Intanke and exhaust manifold for racing engine
Chuchma, Ondřej ; Zháňal, Lubor (referee) ; Beran, Martin (advisor)
This Master’s thesis is focused on design and optimalization of intake and exhaust system of the C20XE engine. It is four-cylinder gasoline engine with stroke volume of two litres, which was produced by car company Opel. This engine is determined for Opel Astra F automobile, that is build for racing. For optimalization of dimension parameters there is used a Lotus Engine simulation software, which simulates one-dimension gas flowing in manifold. 3D CAD models are made in Pro ENGINNER software.

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.
