Powertrain of in-line five-cylinder spark ignition engine
Hájek, Daniel ; Rauscher, Jaroslav (referee) ; Píštěk, Václav (advisor)
Objective of bachelor’s thesis is, for noted geometric, thermodynamic and operation parameters cylindrical unit of five-cylinder spark-ignition engine, perform calculation of thermodynamic cycle, project basic proportion of piston group and for noted operation modes perform strength check of connecting-rod eye. Rated value verify, if corresponded with true value of spark-ignition engine. In preamble is stated basic use of spark-ignition engines, their operation principle and design concept. The bachelor’s thesis is consists from description of calculation and supplement, where is calculation done. The calculation is consists from three parts. The first part is calculation of thermodynamic cycle, in the second part are calculated forces reacting to piston group and third part is strength calculation and check of connecting-rod eye. In the last part is results evaluation of calculation, show a methods of calculation and a new trends spark-ignition engine of evolution.

Crank mechanism of in-line three-cylinder diesel engine
Cetkovský, Martin ; Rauscher, Jaroslav (referee) ; Píštěk, Václav (advisor)
Objective bachelor’s thesis, which will be achived is, for scheduled elementary geometric, thermodynamic and operation parameters cylindrical unit of in-line three-cylinder diesel engine, perform calculation of thermodynamic cycle, design elementary dimensions of piston group and for schedule operation modes perform strength check of connecting-rod eye. Consequently rating value compare with value of real true diesel engine. In introduction is explained basic principle of diesel engine and their design concept. The bachelor’s thesis is consisted of description of calculation and supplement, where the calculation is done. The calculation is accomplished in three parts. Thermodynamic cycle is solved in the first part. Forces acting on piston group are solved in the second part and strength calculation and check of connecting-rod eye is solved in the third part. The end is focused on evaluation of calculation and recent solution of diesel engine.

Piston for 108kW 4-stroke SI-engine
Burýšek, Karel ; Dundálek, Radim (referee) ; Svída, David (advisor)
This Bachelor work is engaged in computing and constructional concept of a piston, intended for the four-stroke spark-ignition engine for private cars whith a view to main dimensions of a piston so that it should be able to work in conditions, which are determinated to, for all the period of it’s lifetime. We need to set strength calculations, which are inseparable part of the project procedure.

Conrod for 73 kW 4-stroke SI-engine
Blanár, Luboš ; Dundálek, Radim (referee) ; Svída, David (advisor)
This bachelor’s thesis deals with computational and constructional design of conrod for four-stroke four-cylinder SI- engine for passenger vehicle. It is necessary to establish main dimensions of the engine and crank mechanism for this project. Beside the design of the main parameters of conrod, a solidity verification on the critical cross-sections is performed which consists of verification of the conrod eye, verification of the conrod body and the conrod head. The part of calculations is also a review of present conrods for four- stroke engines and their development.

The analysis of website in terms of SEO
Volčíková, Anna ; Sova, Martin (advisor) ; Čermák, Radim (referee)
This bachelor thesis solves the question how to care for a new company website to reach the top positions in the search results of full-text search engines. The problem is solved by analyzing a particular website from the point of search engine optimization (SEO). First it explains how the search engines work, what influences sorting of results and how the results are displayed. These theoretical findings are applied to a practical situation. The result of the analysis is recommendation for an accounting firm Daspet s.r.o. and for other operators of websites, how to optimize a new website in terms of SEO.
