Performance optimisation of turbocharged engine for Formula Student
Špičák, Milan ; Janoušek, Michal (referee) ; Svída, David (advisor)
Diplomová práce je zaměřena na výběr pohonné jednotky pro Formuli Student, sestavení spolehlivého výpočtového modelu za využití pokročilého testování. Dále se zaměřuje na přípravu vhodných podmínek pro testování, samotné testování a následnou kalibraci řídicí jednotky pro validaci simulací a také pro efektivní a spolehlivé řízení motoru v náročných závodních podmínkách. Je zároveň součástí komplexního projektu, který se zabývá celkovým vývojem přeplňovaného jednoválcového motoru pro tým TU Brno Racing.

Station for measuring valve train mechanism
Martinček, Matej ; Beran, Martin (referee) ; Svída, David (advisor)
Diploma thesis deals with valvetrains of internal combustion engines. For the right function and for the future development of valvetrains is important to know their characteristics. One of the characteristic is dependence of valve lift on angular position of camshaft. For this purpose was developed and build universal station where is possible to measure this characteristic.

Design of Single Cylinder 4-stroke SI Engine
Číž, Petr ; Rasch, František (referee) ; Rasch, František (referee) ; Svída, David (advisor)
Thesis deals with design of the experimental single-cylinder spark ignition engines for research purposes. The main purpose of this work is the design crankcase. Summary of possible constructions of spark ignition engines is included. Basic dimensions and 3-D design of the experimental engine resulted from the summary. The numerical analysis of proposed crankcase in ADAMS (MBS) and ANSYS (FEM) software environment is also part of the work. Generally, the proposed solution of the experimental engine was focused on the universality and simplicity of the design.

Camshaft design for Miller cycle engine
Dúlovcová, Gabriela ; Beran, Martin (referee) ; Svída, David (advisor)
The main aim of this thesis is the analysis of influence of inlet valve opening length and compression ratio on performance and thermodynamic parameters of Miller cycle using GT-SUITE software. Next step was an optimization of inlet and exhaust valve timing with goal of increasing motor effective power. For chosen option was designed cam shaft with regard of kinematic and dynamic magnitude courses.

Computational model of an CR diesel combustion engine
Kučera, Vlastimil ; Beran, Martin (referee) ; Svída, David (advisor)
Combustion-engine control is one of the most important parts of engine application and has a direct impact on its characteristics. Diploma thesis shows the preparation of a test engine and its installation to test cell. It describes measurement and data post processing necessary for common-rail diesel engine control and their application in the creation of a mathematic model in GT-SUITE.

Intake and exhaust manifold for the truck engine
Koksa, David ; Beran, Martin (referee) ; Svída, David (advisor)
The master’s thesis is focused on creating a thermodynamic model of the diesel engine for heavy commercial vehicle. After the model was created, new intake and exhaust pipes are designed based on simulations. Those proposed pipes variants are compared with the series design. After evaluating individual variants, the final version of the new pipes is selected and 3D model for this version is created.

Electronic speed controller
Šimbera, Michal ; Kučera, Pavel (referee) ; Svída, David (advisor)
The thesis deals with the design, realisation and functional verification of an electronic cruise control unit. Required inputs, outputs and controller of the control unit are identified first. The design and layout of the electronical components, including the processor, power supply and other necessary hardware is discussed. The algorithm for the control unit is developed in C/C++ and thoroughly analysed. The functionality of the cruise control unit equipped with the algorithm is verified through a case study performed on a combustion engine.

Four-stroke single cylinder engine of racing motorcycle for MX1 class
Kučera, Michal ; Svída, David (referee) ; Drápal, Lubomír (advisor)
This thesis describes the design of single-cylinder four-stroke racing motorcycle with a displacement of 450 cm3. The introduction describes the MX1 class motorcycle engines design and basic parameters of the designed engine. This is followed by comparing construction of crank mechanism parts meeting strength calculations with components of contemporary racing engines. The next section describes the design of the timing mechanism, balance shaft, cylinder head, engine cylinder, gearbox shaft location and crankcase lubrication and cooling system.
