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.

Variable turbocharger turbine geometry
Řezáč, Vojtěch ; Dlugoš, Jozef (referee) ; Drápal, Lubomír (advisor)
This thesis is dedicated to design of turbocharger’s boost pressure regulation using variable turbine geometry. In this thesis are mapped commonly used methods of turbine flow regulation. With respect to all information collected there were created new designs which were compared between each other and with currently used Garrett VNT system focusing on performance, flow area and operating forces which were obtained using advanced numerical methods in ADAMS View software. At the end of this thesis are presented benefits and drawbacks of each design. In the very end are presented next steps in further development.

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.

Classification of wear relevant duty cycles of turbocharger validation
Kovaříková, Lucie ; Žatko, Miroslav (referee) ; Lošák, Petr (advisor)
Tato bakalářská práce se zabývá shromážděním dat z testů pracovního cyklu motoru, jejich kontrolou a určením kritérií třídění. Dále pak návrhem a vyhodnocením metodiky charakterizace cyklů zatížení, zaměřených na očekávané výsledné opotřebení kinematických komponent turbodmychadla. Vyhodnocení a kontrola dat jsou provedeny pomocí dvou nástrojů - Python a Matlab. Výstupem této práce jsou dvě navržené metodiky zpracování pracovních cyklů na základě zpracovaných dat - obecné zpracování dat pracovního cyklu a analýza pracovního cyklu, včetně polohy aktuátoru.

Development of combustion engine turbochargers
Franc, Vladimír ; Dlugoš, Jozef (referee) ; Řehák, Kamil (advisor)
This bachelor's thesis is a research project focused on the development of turbocharger technology for diesel and gasoline engines. The work is divided into four chapters. The first chapter is a general description of the construction, basic principles and key components of turbochargers. Next, the history of turbocharging will be briefly summarized. The third chapter is devoted to particular construction methods and finally new development trends will be discussed too.
