Computational Tool for Gas Flow Modeling through the Piston Assembly
Vitteková, Zuzana ; Dlugoš, Jozef (referee) ; Raffai, Peter (advisor)
The main topic of this bachelor’s thesis is to create a graphical users interface (GUI) in Matlab, facilitating the entry of input parameters for the calculation of the gas flow through the piston assembly and its evaluation. The first part is dedicated to the theory of piston rings followed by an introduction into the gas flow problematics. The second part concerns the procedure of creating the aforementioned GUI.

Experimental Stand for Determination of Turbocharger Lubricant Consumption
Kuhajdik, Matej ; Doman, Jozef (referee) ; Novotný, Pavel (advisor)
This work solves the problem of lubricant consumption in the turbocharger and air blow–by from the compressor part of the turbocharger into the bearing housing. The chosen problem is solved by the design of the test mechanism that will be used in the technical experiment. The experiment provides analysis options for the GT35 turbocharger rotor seal. Part of the work is a complete drawing documentation of the test equipment, installation procedure and instructions for operating the equipment.

Turbocharger seals
Holík, Petr ; Fiedler, Jan (referee) ; Škorpík, Jiří (advisor)
This master’s thesis deals with theme of turbocharger seals. The aims of a thesis are to compare a turbocharger seals used in PBS Turbo turbochargers and to describe a testing of a seals. Principle of turbocharging and types of turbocharger are described in fist part. Next point of the thesis is describing of a face seals and non-contacting seals. The main part of the thesis describes kinds and reasons of seals testing; also contains comparison between labyrinth seals and piston ring, comparison of seals of PBS Turbo’s turbochargers and assesses the impact of turbocharger angle on the tightness of the seal.

Piston Rings of Modern Petrol Engines
Cupák, Václav ; Maršálek, Ondřej (referee) ; Raffai, Peter (advisor)
This bachelor thesis deals with issues of piston rings used in modern petrol engines. The first part is focused on describing of functions and requirements with which piston rings must deal with. Next part is aimed on shapes of piston rings. Materials from which are piston rings made of are part of third chapter. For proper function, it is important to make some surface treatment. The last chapter contains surface treatment of piston rings.

Piston for 108kW 4-stroke SI-engine
Burýšek, Karel ; Dundálek, Radim (referee) ; Svída, David (advisor)
This Bachelor work is engaged in computing and constructional concept of a piston, intended for the four-stroke spark-ignition engine for private cars whith a view to main dimensions of a piston so that it should be able to work in conditions, which are determinated to, for all the period of it’s lifetime. We need to set strength calculations, which are inseparable part of the project procedure.

Arrangement of Piston for BMW 2,5 TDS 4-stroke CI-engine
Rada, Lubomír ; Drápal, Lubomír (referee) ; Svída, David (advisor)
In this bechelor work presentation and design a four-stroke piston diesel engine with direct injection diesel by 130 kW, which is used in BMW vehicles. When choosing key dimensions come out of the original dimensions of the piston, used in diesel engine with indirect injection into the vortex chamber 105 kW of power. The draft of the main dimensions of the piston followed by strength calculation of the critical points of the piston.
