Piston group of in-line four-cylinder gasoline engine
Král, Stanislav ; Novotný, Pavel (referee) ; Píštěk, Václav (advisor)
The aim of the thesis, it is strength control group of ordinary four-cylinder piston gasoline engine. In the first part of the specified thermodynamic, geometric and operational parameters of the motor piston group will calculate the thermodynamic cycle. Furthermore, we see the effects of force acting on the piston group in the most strained moments of the cycle. For the reconstructed load piston group perform voltage control in piston pin and strength control rods of the eye. In conclusion, we compare the calculated values of permissible stress values and find a design safety factor for the part.

Connecting Rod Design of Diesel Aircraft Engine
Maršálek, Ondřej ; Píštěk, Václav (referee) ; Novotný, Pavel (advisor)
The thesis deals with complex connecting rod design of two stroke diesel engine with regard to minimising its weight. Three versions of design are suggested and for each of them the stress analyses are implemented and the fatigue safety factors are determined. On the basis of results of implemented analyses and evaluation of all the aspects the most appropriate design is chosen and the production drawing is drawn according to it. In the conclusion, hydrodynamic lubrication plain bearings, which are the integral part of every connecting rod, are designed.

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.

Four-cylinder in-line gasoline aircraft engine
Kučera, Ondřej ; Kučera, Pavel (referee) ; Píštěk, Václav (advisor)
The thesis deals with the structural design of a steel connecting rod for the aircraft engine Walter Mikron III, which is currently still manufactured and developed by company PARMA-TECHNIK, s.r.o. The proposed connecting rod would replace the current duralumin connecting rod. The work also contains a strength analysis of the designed component, in which it was aimed to verify the stress on the connecting rod, based on which the fatigue safety factor was performed. This is crucial for dynamically stressed parts of internal combustion engines. Furthermore, was investigated the effect of the change of the connecting rod on the torsional vibration of the crank mechanism. For this purpose, was built a discrete torsion model. The output of the whole work is the drawing documentation of the new connecting rod, meeting the requirements for application in an aircraft engine.

Use of the CAM software PowerMILL 2018 for machining of a mold
Drbal, Jindřich ; Sliwková, Petra (referee) ; Polzer, Aleš (advisor)
The subject of submitted diploma thesis is complete structure of procedures necessary for the designing and subsequent production of forging dies for production of semi-finished connecting rods. The initial part deals with the design of forging die. Following part is consisted of materials used for production of this type of tools. Ensuing is proposal of tooling for machining of the die following with simulation of the milling processes.

Engine Conecting Rod Analysis Inluding Bolts Influence
Cseh, Csaba ; Svída, David (referee) ; Ramík, Pavel (advisor)
Csaba CSEH Engine Connecting Rod Analysis Including Bolts Influence DW, ITE, 2008, 75 pp, 88 fig. The aim of my diploma work is a stress analysis in the material of a connecting rod during a stationary engine regime. Dynamic forces from the connecting rod‘s motion and the forces acting on the bolts are included in the calculations. The whole stress analysis is based on a FEM designed application on a model, that was created in a CAD system package according to the real component.
