Turbocharger Performance Measurement
Ušiak, Michal ; Janoušek, Michal (referee) ; Vondrák, Adam (advisor)
The bachelor’s thesis deals with recent methods of measuring turbocharger characteristics. Besides an introduction to fundamental performance characteristics, such as compressor map and turbine map, thesis contains description of experimental methods of collecting such data, which is essential for designing a turbocharged power unit. Description of main parts of the test stands and limitations consequent upon the measuring methods is supposed to offer basic knowledge of turbocharger design validation to the reader. As an extension overview of tests increasing accuracy of these characteristics and a few additional and safety tests is presented. Examples of use of these characteristics in engineering calculations should give an image of significance of creating computational model from experimental collected data, which describes thermodynamics of the turbocharger.

Design of Experimental One-cylinder Engine with Floating Liner
Svoboda, Radovan ; Svída, David (referee) ; Novotný, Pavel (advisor)
The aim of this master`s thesis was to design a single-cylinder test engine for measuring of the friction forces between the piston group and the cylinder liner. Main engine parameters are based on the common production engine. A floating liner device was chosen for a friction forces measurement. It was necessary to solve an attachment and sealing of the floating liner. Stress-strain analysis of the floating liner has been done. Next step was to re-design a production crankshaft also with a connected balancing devices for single-cylinder engine. Powertrain was seated in a completely new units. Finally the engine was completed and mounted on a stand.
