Modification of Naturally Aspirated Engine to Turbocharged Engine
Fajkus, Martin ; Beran, Martin (referee) ; Svída, David (advisor)
Aim of this diploma thesis is the modification of naturally aspirated engine for Formula Student competition to turbocharged version. Modification which were made are based on the issue knowledge and calculations. The input data were obtained from 3D scanning and measurements, at the school laboratories. All 3D models were created in Pro / Engineer. Input data for the computional analysis was developed in Lotus Engine Simulation. Computational analysis was performed in ANSYS by finite element method. Calculations had to simulate a piston behavior at the critical situations where the engine is under the maxiumum load.

Formula 1 Engines
Kaňa, Roman ; Ramík, Pavel (referee) ; Dundálek, Radim (advisor)
This bachelor thesis describes construction of some functional parts of the Formula 1 engine. In the first part I focused on crankshafts, connecting rods, pistons, valve gears and compared them with serial produced engines. The work further continues with the introduction of some unconventional solutions used on Formula 1 engines and comparison of the characteristics of known power units.

Piston of 4-stroke SI-Engine with 75 kW Output Power
Kalugin, Ivan ; Svída, David (referee) ; Dundálek, Radim (advisor)
This bachelor's thesis deals with calculating suggestion and structural solution of a piston for a 4-stroke petrol engine with 75kW output power. The structural solution includes determination basic dimensions of engine and crank mechanism. Final part is devoted to fort control of critical piston sections on the base of kinematics crank mechanism and indicator diagram.

Piston for 43kW 4-stroke SI-engine
Vaculík, Tomáš ; Svída, David (referee) ; Dundálek, Radim (advisor)
This bachelor’s work describes a calculational project and design solution of a piston for 43 kW power output, four-stroke petrol engine and depicts basic sizes of this engine. The piston was constructed to be able to work in hard conditions that the piston faces in the combustion area. An important part of my thesis is the piston calculation of its resistancy by which we verify corectness of suggested sizes of the piston.

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.

Powertrain of in-line four-cylinder spark ignition engine
Mačuga, Martin ; Rauscher, Jaroslav (referee) ; Píštěk, Václav (advisor)
According to given to cylinder diameter, stroke and ideal indicator diagram we will investigate with maximum cylinder pressure and further design for proportions piston insider ( piston and piston - pin) as well as piston rod. Then shall do strength calculation upper connecting-rod eye according to given to calculations namely for the select material of piston rod. In the end we evaluate the select material whether is for suggested piston rod fit.

Piston for SI CNG 140 kW Engine
Hrouzek, Jan ; Drápal, Lubomír (referee) ; Svída, David (advisor)
This master’s thesis deals with the piston for modified engine 1.4 TSI from Volkswagen concern. It includes calculation of kinematics and forces reactions of the crank mechanism of the engine for speed 6071 rpm elaborated in the program Mathcad Prime. Further the work includes calculation for reducing the magnitude of lateral force and design of several variants of the piston. For the proposed design variants of the piston are performed FEM analysis of mechanical state of stress and comparisons of contact pressures in the program ANSYS Workbench.
