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.

Cylinder Deactivation for Internal-combustion Engines
Fridrichová, Kateřina ; Janoušek, Michal (referee) ; Drápal, Lubomír (advisor)
This bachelor’s thesis focuses on a technology reducing fuel consumption and emissions called cylinder deactivation. The evolution of the technology is described in the first part of the thesis together with explanation of the nature of fuel savings. The description of consequences associated with usage of the technology and possible design approaches for gasoline engines are written in the following part. The thesis also incorporates the results of test performed on diesel engines, where the technology is not currently in production. The last part includes other components used in engines with cylinder deactivation, especially vibration absorbers, together with some examples of application of this technology.

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.
