Powertrain of in-line five-cylinder diesel engine
Zarambukas, Michalis ; Novotný, Pavel (referee) ; Píštěk, Václav (advisor)
The aim of this graduation theses is geometrical and thermodynamic calculation of determined five-cylinder diesel engine and calculation of operation parameters of cylindrical unit and then to compare them with real motor and strike the balance. Other step is to work out thermodynamic cycle and draw the result in p-V diagram. Then to calculate power, effecting on piston which includes proposal of basic proportion of piston and wrist pin, and it follows weigh of piston group and maximal quickening and inertial force of piston group, calculation of specific pressure and pressure in wrist pin. Other purpose is to determine basic proportion for piston rod and to focus on material qualities of con rod eye and bronze case, determination of maximal pressure due to inertial forces comming from gas pressure and security against possible slip and tiredness. At the beginning is described diesel engine from its foundation, its activity to its use in company. At the close are reviewed the results of the calculations.

Piston for 147kW 4-stroke SI-engine
Hejda, Tomáš ; Svída, David (referee) ; Dundálek, Radim (advisor)
This bachelor’s thesis deals with the design of piston for 147 kW 4-stroke SI-engine, which is used in Octavie 2,0 TFSi RS. The work is focused to main dimensions of the piston, to make it able to work in difficult, temperature and strength conditions as exposed to in its lifetime. One of the most important part of design this piston is strength calculation.

Powertrain of in-line three-cylinder diesel engine
Riemel, Pavel ; Novotný, Pavel (referee) ; Píštěk, Václav (advisor)
Objective of bachelor’s thesis is for main predetermined geometric, thermodynamic and operation parameters cylindrical unit of line three-cylinder compression-ignition engine perform calculation of thermodynamic cycle, project basic dimensions of piston group and for noted operating modes perform strength check of con rod eye. Resulting values compare with comparable compression-ignition engine and verify its appropriate functionality. In preamble of work is mentioned compression-ignition engine, its basic usage, principle of function and description its main parts. The work is compound of two basic parts. The first contains description of calculation with related graphic and the second calculating supplement in which are calculations of thermodynamic cycle, forces reacting on piston group, strength calculation and control of con rod eye. At the close results of calculation are analysed.

Crank mechanism of in-line four-cylinder spark ignition engine
Marek, Petr ; Rauscher, Jaroslav (referee) ; Píštěk, Václav (advisor)
Objective of this bachelor’s thesis is for given geometric, thermodynamic and operation parameters cylindrical unit of in-line four-cylinder spark ignition engine perform calculation of thermodynamic cycle, project basic proportion of piston group and for given operation modes perform strength check of connecting-rod eye. In the introduction is described ordinary use of spark ignition engines, several details of history of their evolution and present most widly used construction. Major text of bachelor’s thesis attend to four main chapters: description of thermodynamic cycle, calculation of forces reacting to piston, strength calculation and check of piston pin and of connecting-rod eye. Supplement consists of accomplishment of these calculations and a few of graphs. In the conclusion is evaluation of performed calculations and there are mentioned technological directions of present evolution of gas-engine.

Piston for 66kW 4-stroke CI-engine
Mikulka, Václav ; Dundálek, Radim (referee) ; Svída, David (advisor)
The content of this baccalaureate work is to make computational proposal and constructional design of the four-stroke diesel engine piston. At the beginning it shortly describes the piston as a part of a piston assembly, basic constructional design of pistons for diesel engines, piston material and the way of production. Further there is a proposal of basic engine dimensions and the crank mechanism. Then there is an elaborated piston dimension on the basis of empirical data. At the end of the work there is a calculation of critical piston cross-sections calculated according to given process of the indicator diagram and designed kinematics of crank mechanism.
