Efficiency of Turbochargers with Variable Nozzle Geometry
Fűri, Peter ; Doman, Jozef (referee) ; Novotný, Pavel (advisor)
This bachelor thesis is focused on providing information about turbocharging of internal combustion engines. It mainly describes the systems of turbochargers with variable geometry. The main intention of this thesis is to describe the function of existing superchargers with variable geometry. The further goal is to compose an analysis regarding to the efficiency of these supercharging systems used nowadays. Considering that this concept is in constant development, the information which was used in this thesis is corresponding to the actually available information.

Experimental Stand for Determination of Turbocharger Lubricant Consumption
Kuhajdik, Matej ; Doman, Jozef (referee) ; Novotný, Pavel (advisor)
This work solves the problem of lubricant consumption in the turbocharger and air blow–by from the compressor part of the turbocharger into the bearing housing. The chosen problem is solved by the design of the test mechanism that will be used in the technical experiment. The experiment provides analysis options for the GT35 turbocharger rotor seal. Part of the work is a complete drawing documentation of the test equipment, installation procedure and instructions for operating the equipment.
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.
Noise Generated by Turbochargers of Internal Combustion Engines
Kříž, Radim ; Novotný, Pavel (referee) ; Doman, Jozef (advisor)
This bachelor thesis is focused on generated noise by turbochargers of internal combus-tion engines. First, construction of turbochargers is described. The next part deals with the term sound and after that the issue of the noise in turbochargers follows. Consequent there are characterized experimental and simulation methods for determining the noise. The last part is focused on design modifications of turbocharger’s parts. The goal of this thesis is make research about origin of the noise by turbocharger during working conditions and design modifications which affect the noise.
Turbine Housing of Turbocharger VNT with Separated Pulses in Exhaust Manifold
Polášek, Jan ; Doman, Jozef (referee) ; Novotný, Pavel (advisor)
This master thesis deals with the design of the turbine housing of turbocharger VNT for supplying separated pressure pulses from the exhaust manifold. Subsequently, the work includes strength analysis of the designed turbine housing. The aim of the thesis is to create components for the supply of separate pressure pulses as close as possible to the turbine. Furthermore, the modification of the existing turbine housing and the assessment of the functionality of the VNT mechanism after this modification and strength analysis. The final aim of this thesis is the creation of 2D and 3D technical documentation of newly designed and modified parts.
