Increasing Performance of Honda 1.6 Engine
Opluštil, Vít ; Beran, Martin (referee) ; Svída, David (advisor)
The aim of this thesis is the description and performance of four-stroke internal combustion engine, an analysis of the options and finding the most effective treatment for a given engine type. In the next section the author deals with computational design turbochargers, chosen for the turbocharged engine modification. Next chapter of work is a design calculation for the choice of the turbocharger, is then constructed a mathematical model of a given engine in the Lotus Engine Simulation software and final results are presented.

Design of Turbocharger Bearing for Low Viscosity Oils
Plánka, Jakub ; Dlugoš, Jozef (referee) ; Novotný, Pavel (advisor)
The first part of the thesis describes journal bearings characteristics, their function and lubrication. The second part of the thesis is about a rotor-dynamics issue and how to use numerical and experimental methods for verification of a new bearing design. The practical part of the thesis is focused on analyse a current design of bearings in MBS. In the last part has been made and verified a new bearing design.

Energy Recovery from Exhaust Gases in an Electric-assisted Turbocharger for Hybrid Vehicles
Calábek, Daniel ; Kudláček, Petr (referee) ; Novotný, Pavel (advisor)
Obsahem této diplomové práce byla vhodnost využití turbodmychadla s přidruženým motor-generátorem pro vybrané typy hybridních vozidel a následná analýza energetických toků pro danou motorovou aplikaci. Přístup prezentovaný v práci zahrnuje termodynamický model motoru v programu GT-SUITE ve kterém jsou zkoumány možnosti energetických toků při změně velikost turbínového a kompresorového kola turbodmychadla. Přistup je aplikován na turbodmychadlo s variabní geometrií lopatek s přidruženým motor generátorem pro donáškové vozidlo, kde je možné při různých zatíženích motoru rekuperovat energii z turbodmychadla. Zároveň byli zjištěny možnosti snížení spotřeby paliva v určitých provozních bodech motoru.

Turbocharger Rotor Balancing
Šárovec, Marek ; Zubík, Martin (referee) ; Knotek, Jiří (advisor)
This bachelor’s thesis is specialized search dealing with issues of turbocharger rotor balancing. This work is divided into three main parts. First part deals with history of turbocharger and basics of turbocharger construction. Second part talks about types of unbalance and how to balance. Also, there is description of balancing machines. Last part depends on previous part because there is application of balancing on automotive turbocharger.

Intake Control Mechanism of Compressor Housing
Bartoníček, Richard ; Doman, Jozef (referee) ; Novotný, Pavel (advisor)
The thesis pursues a design of mechanism for controlling the amount of air sucked by a turbocharger compressor. In the first part, there is a brief description of a turbocharger and its characteristics, in the second part the usual regulation methodologies are presented. Third, the main part describes the creation of the mechanism from concept drafts and their comparison, through the kinematic and force analysis of control parts, to the complete packaging a connection to the compressor housing. The fourth part is dedicated to the mechanism analysis in the terms of ability to perform as required.

Turbocharger Vibrations Generated by Internal Combustion Engine
Schulla, Radek ; Vacula, Jiří (referee) ; Novotný, Pavel (advisor)
The content of this master’s thesis is the issue of turbocharger vibrations due to excitation from the internal combustion engine. The theoretical part deals with the noise and vibrations generated by turbochargers and internal combustion engines. It also discusses the effect of vibration on the turbocharger and its individual parts, including the effect of the internal combustion engine. Subsequently, a turbocharger model is created in ADAMS software, the rotor response in turbocharger operating speeds to various excitation frequencies is analyzed and finally the safety of fluid bearings is evaluated and modifications to reduce vibrations are proposed.

Turbocharger Regulating VNT Mechanism Load Simulation
Cetkovský, Martin ; Svída, David (referee) ; Vančura, Jan (advisor)
This diploma thesis deals with turbochargers with a focus on the ways of their regulation. The main subject is to design CFD simulation for a turbocharger with VNT mechanism at specific positions. Simulation is based on the turbocharger Garrett by Honeywell, for which measurement was realized. Finally torques acting on the vanes are evaluated from the simulation. The means of results improvement are considered at the end of the thesis.
