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.

Powertrain of in-line four-cylinder spark ignition engine
Parchański, Martin ; Rauscher, Jaroslav (referee) ; Píštěk, Václav (advisor)
Objective baccalaureate work is count for engaged four - cylindrical petrol motor geometric, thermodynamic and operation parameters and subsequently rated funds make up real motor and strike a balance. Perform calculation thermodynamic cycle simulation power cycle and draw p- c diagram, assesment basic size piston and piston pin, assesment inertial force applied on piston group, calculation specific pressure and tension at piston pin, assesment basic proportions connecting rod, calculation tension in connecting-rod eye in consequence heating - up bronze chuck, assesment maximum tension in connecting-rod eye in consequence inertial force and from pressures gas and determine safety against yield strength and endurance strenght. In introduction work is schematic working principle gas engine motor and schmatic most frequent principle raising achievement. At the close are capitalized computing result.

Cylinder unit of motocycle two-stroke engine
Stejskal, Miroslav ; Novotný, Pavel (referee) ; Píštěk, Václav (advisor)
Miroslav STEJSKAL Cylinder unit of motorcycle two-stroke engine In the beginning is briefly described two-stroke engine features. Furthermore, according to the set of basic geometric and thermodynamic parameters, the maximum pressure in the cylinder during one engine cycle. For the selected operating modes are carried out strength tests of the upper piston and connecting rod eye. In conclusion, the results are evaluated.

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.

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 group of in-line three-cylinder diesel engine
Drdla, Marek ; Novotný, Pavel (referee) ; Píštěk, Václav (advisor)
The aim of this thesis is to calculate a thermodynamic cycle of given engine with basic geometric, thermodynamic and operating parameters of is piston category. Then, a disign of cylindrical unit and strengrh check of piston, piston pin and conrod eye, follows. There is preliminary mentioned the principle of Diesel engine function. The body of the thesis is divided into five chapters and the attachment. At first two chapters, there are basic parameters of the engine and Sabat thermodynamic cycle described. Next chapters are focused on force load of piston, piston pin and static and dynamic stress of conrod eye. Numerical calculation of three-cylinder Diesel engine Zetor 5202 is given in the attachment. In conclusion, there is the procedure and the analysis of calculation described and zhe calculation is evaluated. Finally, a comparison of theoretical concept and real conditions is given.
