Up-to-date Methods of Supercharging
Strouhal, Pavel ; Janoušek, Michal (referee) ; Dundálek, Radim (advisor)
This thesis is focused on the currently used methods of supercharging internal combustion engines in passenger vehicles. It discusses not only the possibility of improving the overall characteristics of the drive unit, but also the design and layout of the filling aggregates, their regulation a possible failures. It also looks into the issue of reducing emissions of the exhaust gases and shows its dependence on the given methods of supercharging. Short mention includes then some today used engines and their mutual comparison. The result is a summary of knowledge required to understand the basic principles of supercharging, which is today the most common way to increase the performance and efficiency of internal combustion engines.

Up-to-date Methods of Charging Processes
Górnisiewicz, Tomáš ; Janoušek, Michal (referee) ; Dundálek, Radim (advisor)
This thesis deals with up-to-date methods of charging processes used in combustion engines of contemporary cars. Major emphasis is put on turbocharged petrol engines. Principles of charging process are explained as well as the most common and extraordinary ways of charging process. Following chapter contains summary of present-day turbocharged and supercharged engines. Final part describes turbocharger failures. Turbo-charging represents an elementary way to increase engine power and allows designing high efficient engines of small dimensions.
