Electric Vehicle Acupack
Huk, Vojtěch ; Šebela, Kamil (referee) ; Janoušek, Michal (advisor)
This bachelor thesis deals with electric vehicle batteries. The battery itself consists of many structural parts that can be made from a variety of materials and assembled in many ways. The first part of this thesis provides an overview of the characteristics a battery should have to achieve the requirements placed on it, and the methods available on the market to meet these requirements. The second part describes in detail the individual components of the battery, including their function and design. Special attention is given to battery cells, describing and comparing the technologies used in them, including graphical representation of this comparison.

Two Stroke Engine Indirect Fuel Injection
Kovář, Michal ; Drápal, Lubomír (referee) ; Janoušek, Michal (advisor)
This diploma thesis deals with indirect fuel injection on new two-stroke engine for motocross sidecar. The purpose of this work was to design the fuel injection system together with length of the fuel injection times. To determine the fuel injection times, it was necessary to determine the complete exhaust system that affect the volumetric efficiency. The conclusions were based on research in the field of two-stroke engines and calculations determining the amount of fuel per one cycle. The injection method together with the location of the fuel injector and type of fuel injector that can be use were determined and then the injection times that can be entered in the ECU.

Crank train of a two-stroke automotive engine
Štrba, Matej ; Janoušek, Michal (referee) ; Drápal, Lubomír (advisor)
The subject of this diploma thesis is the analysis and comparison of three-cylinder two-stroke engines with a displacement of 1000 cm3 of the Wartburg 353. The introduction of the thesis is a research that discusses the history of car production and development in Eisenach during the second half of the 20th century. The main subject of research is the engine, to which the vast majority of work is devoted. Using the available simulation tools, the cylinder pressure indication is determined, the crankshaft of the two engine variants is subjected to balance analysis, dynamic analysis in terms of torsional vibrations and bearing load is performed using the MBS method, then the two variants are compared.

Parameters for 1D Single Cylinder Engine Simulation
Stryja, Štěpán ; Šebela, Kamil (referee) ; Janoušek, Michal (advisor)
The relationship between the 1D simulation and the corresponding input parameters is addressed in the paper. The one-dimensional simulation is demonstrated in the GT-Power environment. The work deals with both experimental and computational analysis of the input parameters. Additive methods of 3D printing of fixtures and subsequent measurement of volumetric flow rates on a Superflow Flowbench SF-260E purge station were used. This procedure led to the final calculation of discharge coefficients. The 3D scanning method, using ATOS 2M equipment, together with subsequent data processing, using the appropriate software, led to the analysis of the valvetrain mechanism and the construction of its kinematics. The practical part was demonstrated on two-cylinder heads of a four-stroke single cylinder engine with a displacement of 125 cm3, with natural aspiration. One of the heads was modified, resulting in volumetric flow increase of 29 % in case of the intake and 15 % in case of the exhaust, compared to the stock head. The work led to the acquisition of key input data for the 1D simulation of the aforementioned engine.

Model engine for F4 class aircraft
Čížek, Petr ; Janoušek, Michal (referee) ; Drápal, Lubomír (advisor)
The diploma thesis deals with the construction of two-stroke engine for the propulsion of a scaled aircraft model, which can fall into the category FAI F4. The introduction of this thesis carries out research and familiarization with the category of F4 aircraft. Part of the research is a brief overview of two-stroke and four-stroke variants of model engines, with the fact that more attention is given to the construction details of two-stroke engines. Subsequently, the design and thermodynamic 1-D simulation of the power parameters of the designed engine are carried out, followed by dynamic simulation to verify the lifespan of the engine bearings.

Engine Block with Integrated differential for Formula Student
Marek, Jiří ; Šebela, Kamil (referee) ; Janoušek, Michal (advisor)
The diploma thesis deals with the design of the integration of limited slip differential of the formula student car into the engine block. To select suitable solution from several considered, a research analysis of possible concepts was first made and then the best possible solution was determined using a decision table. A 3D model was then made for the selected concept based on the original engine block, digitalized by using a laser 3D scanner. The resulting model was then evaluated and built into Dragon X.

Electronic supercharger for Formula Student
Matoušek, Patrik ; Šebela, Kamil (referee) ; Janoušek, Michal (advisor)
The main goal of this diploma thesis is to verify the application of the Electric compressor in the Formula Student monopost category. Diploma thesis is focused on the computational model and analysis of the combustion engine in the GT-POWER software. Outputs from this calculation are used for the design of the main parameters of battery pack. In the final part of the thesis, the monoposts with ordinary turbocharger and with the electric compressor are compared in the lap time simulation in the Autocross discipline.
