Increasing the efficiency of an internal combustion engine for small autonomous vehicles
Celý, Martin ; Beran, Martin (referee) ; Svída, David (advisor)
The work deals with the analysis of various possibilities of increasing the efficiency of a small internal combustion engine potentially usable for use in the field of autonomous devices of smaller dimensions. It contains an outline of the problems of modern smaller autonomous means and an analysis of available drives designed for them, especially an analysis of propulsion by internal combustion engines. In his next part of the work he provides information about the created mathematical model of the demonstration internal combustion engine in the GT-Power program and an analysis of places where and in what ways its efficiency can be increased. The design of two such components together with the evaluation of the achieved results offers the conclusion of this work.

Supercharged SI engine
Janíček, Michal ; Bazala, Jiří (referee) ; Beran, Martin (advisor)
The diploma thesis deals with the selection of an eligible supercharger for cooperation with the internal combustion SI engine Honda K20A2. The first part is dedicated to the research referring to an issue of charging and a brief description of particular supercharger types. However, the main part of the thesis consists in the formation of proposal calculation and the tentative choice of the eligible type of supercharger. The part of the work is also the description of the assigned engine and the measurement of its parameters. The most extensive part of the thesis deals with the making of computational model of the atmospheric and supercharged version of the engine and the consecutive simulations in the GT-Power software. Finally, gained results are evaluated and the computational study of the cooperation of the selected supercharger with assigned combustion engine is made in the last part of the diploma thesis.

Cooled EGR system loop architecture for gasoline engines
Pospíšil, Juraj ; Svída, David (referee) ; Bazala, Jiří (advisor)
Táto diplomová práca je zameraná na preukazovanie vplyvov rôznych architektúr spätnej recirkulácie spalín na preplňované benzínové motory. Simulácie boli vytvorené v termodynamickom simulačnom programme GT-Power. Práca začína porovnávaním vplyvov spätnej recirkulácie na ustálené stavy motora, najmä z hľadiska spotreby, ktoré sú následne implementované do tranzientných modelov, simulujúc emisné testovacie cykly. Na konci práce sa venujem vplyvom spätnej recirkulácie na funkciu oxidačno-redukčného katalyzátora a na funkciu turbodúchadla.
