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.

Recuperation systems in automotive technology
Běhoun, Lukáš ; Repka, Martin (referee) ; Zháňal, Lubor (advisor)
The aim of this bachelor thesis is to examine the methods of energy recuperation in the automotive technology. The first section explores the historical development of the recuperation systems spanning from the end of the 19th century to the present day. The second section is following with the division of the recuperation systems in accordance with the method of their energy storage and their transmission. This is consecutively supported by three examples of use for each of the systems. The third section offers a comparison of the individual cumulative units. Furthermore, it offers a comparison of all the types of systems used in bus transportation. The fourth section analyses the fuel consumption by a bus without a recuperation system and by an identical bus with the Bosch Rexroth recuperation system. This is supported by calculations. Subsequently, the above systems are scrutinized from an economical point of view. The last part deals with the possible development of recuperation systems in the future.

Visualisation of telemetric data
Kolář, Michael ; Hejtmánek, Petr (referee) ; Zháňal, Lubor (advisor)
The main aim of this bachelor thesis was the creation of an application in the Unity engine, which would enable real-time rendering of a vehicle and its suspension components. The positions and rotations of the individual parts are governed by the data that originate from the Matlab application based on simulation or real measurement.

Alternative conceptions of combustion engines
Šťáva, Martin ; Fojtášek, Jan (referee) ; Zháňal, Lubor (advisor)
The subject of this bachelor´s thesis on the topic Alternative conception of combustion engines is description of chosen historical and present alternatives to conventional piston combustion engine with crankshaft. The aim of this thesis is to create thesis that relates description of historical evolution of alternative construction combustion engines. Alternatives are described in terms of construction, operating principle and properties. In past were developed plenty of different conceptions of combustion engines. However most of them have never been successful because of many technical problems, complicated construction or other shortages.

Machine learning and signal processing
Kolář, Michael ; Fojtášek, Jan (referee) ; Zháňal, Lubor (advisor)
This thesis deals with the possibility of using neural networks in the analysis of a racing vehicle telemetry data. The analysis consists of finding and classifying the driving states of the vehicle as well as reconstruction and prediction of the data signal. The thesis consists of a research of machine learning focusing on neural networks. It describes the main types of the most commonly used neural networks with the description of their structure and their learning process. It also deals with the problem of classification and an in-depth analysis of the signal prediction and reconstruction. The conclusion is devoted to the implementation of the network into a TeleMatrix application.
