Turbocharger
Růsek, Lukáš ; Novotný, Zdeněk (referee) ; Fiedler, Jan (advisor)
A masters thesis deals with the question of deisel engine boosting by rotary turbochargers. The objective of the thesis is to propose suitable turbocharger´s concept for defined diesel combustion engine with power of 430 [kW]. The air boosting pressure is controlled by exhaust gas flow through the turbine and different EGR regimes, which are considered in the basic and corrected calculations. The final turbocharger´s concept is proposed to satisfy the defined technical requirements. Next technical recommendations are briefly summarized in the thesis conclusion for following turbocharger´s concept application.

Increasing AR67203 Engine Performance
Smilek, Lukáš ; Beran, Martin (referee) ; Svída, David (advisor)
The aim of this diploma thesis is supercharging of SI engines and design influence on performance. The main objective of this thesis is to propose appropriate modifications on AR67203 engine of Alfa Romeo 155Q4 personal vehicle in order to achieve significantly better performance parameters and a constant torque in the widest possible speed range. That is why I analyze design and modifications that affect the overall engine performance and their appropriate application to the selected engine. An important point of this thesis is the right choice of turbocharger, in order to have an effective cooperation with a modified engine. The calculation study and the simulation in Lotus Engine Simulation software serve this purpose. I also give information about ECU programming. The results, as well as a practical output in the form of measured performance parameters of modified engine, are evaluated at the end.

Increasing SI Engine Performance by Turbocharging
Hájek, Daniel ; Beran, Martin (referee) ; Svída, David (advisor)
The master’s thesis deals with the question of petrol engine boosting by rotary turbochargers. The objective of the thesis is to project suitable turbocharger for defined single-cylinder petrol engine. After selecting the suitable turbocharger type it will follow the construction of the computational model of the single-cylinder turbocharged petrol engine in the Lotus Engine Simulation software. In the computational model is boost pressure regulated by the turbine waste gate valve. The result will be the boost pressure values scheme for the highest possible torque so that the maximum combustion pressures will not exceed the value of 9,5 MPa. There are summarized findings and results in the conclusion of the thesis.

Návrh systému přeplňování turbodmychadlem
Mahr, Ivoš
This thesis on turbocharging system design deals with the design of the turbocharger for gasoline internal combustion engines. The work is divided into five thematic areas. The first part presents the history of turbochargers and their use. The second part deals with the whole system, turbocharging and transformation of energy. In the third part of the structural design of the turbocharger. The fourth part is the analysis and design of turbochargers for gasoline internal combustion engine on the target output of 350 kW at displacement of 1999 cm3. The result is a proposal from the catalog turbocharger manufacturer Garrett global brands owned by Honeywell. In the last section the results are verified by measuring the motor test.
