Supercharging of internal combustion engines
Vrána, Jan ; Jedelský, Jan (referee) ; Štětina, Josef (advisor)
In supercharging are applied mainly two ways - turbocharging or charging using a mechanical compressor. The aim of thesis was to compare the ideal cycles of internal combustion engines with ideal cycle of supercharged engine, write down the main problems of supercharging, especially the border of self-ignition of fuel and detonation ignition, advantages and disadvantages of different methods of supercharging and its effect on engine efficiency. Further, there are given basic construction designs of turbochargers and air coolers and some special methods of supercharging and cooling.

Design For Six Sigma
Greplová, Kristýna ; Fiala, Alois (referee) ; Koška, Petr (advisor)
The aim of the master’s thesis is analysis of practical application limits of waste-gate TwinScroll turbocharger located in BMW X6 M vehicle by using DFSS (Design For Six Sigma) tools. The goal is to create a special measurement device for a measurement of waste gate leakage with chance of testing all sorts of characteristics having impact on key parameters of turbocharger.

Castings from TiAl alloys for the turbochargers
Kudýn, David ; Malec, Silvestr (referee) ; Zemčík, Ladislav (advisor)
The bachelor thesis is focused on the analysis of intermetallic alloys TiAl. First of all, it is analysed their properties and the way how they change depends on their treatment and influencing of alloying elements. Then ways of utilization in practice are stated here. Attention is concentrated especially on turbochargers wheel and their comparison to convention materials. After that individual options of melting and casting and materials for melting crucibles and moulds associated with them are there discussed. In the end, the thesis has analysed the ways of recycling of residual material.
