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.

Slide bearing parameters of modern combustion engines
Dvořák, Martin ; Píštěk, Václav (referee) ; Novotný, Pavel (advisor)
The objective of this bachelor‘s thesis is to provide general information on sliding bearings and their advantages and disadvantages. The thesis is divided into five parts that deal with individual topics and issues. The first one is concerned with the bearings themselves, their partition and development. The second part compares sliding bearings and rolling contact bearings and their pros and cons. The next part then describes their main parameters, e.g. the friction loss or various lubrication methods. The fourth one summarizes several examples of practice, like lubricating in extreme working conditions and an overview of bearing failures. The last part deals with the construction of sliding bearings used in combustion engines, materials used to produce sliding bearings and with the issue of lubrication, which is essential for this type of bearings.

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.

Piston and Connecting Rod Assemblies of a SI Engine
Adam, Petr ; Janoušek, Michal (referee) ; Drápal, Lubomír (advisor)
This bachelor's thesis is focused on the design piston and connecting rod set, where was chosen for design the six-cylinder four-stroke spark-ignition engine. In design is going from existing engine, where are designed all parts of piston and connecting rod set on base of it. Subsequently is constructed mathematical model of kinematic and dynamics. Finally is going from dynamic for execution of strength control.

Mass Reduction of 4-cylinder In-line CI-engine Con-rod
Zatloukal, Lukáš ; Ramík, Pavel (referee) ; Novotný, Pavel (advisor)
This diploma thesis applies to the light-weight itself of a connecting rod of a mass-produced tractor-engine. As a one of the most important and first part of this task is creating a 3D simulation model of a connecting rod. The strenght calculation is following skip factor of the light-weight, the exact calculated dimension of relieve is providing by means of an engine imbalance including the connecting rod. The outcome data of research are instrumental to the new relieve and strengthen 3D design. The conclusion and ending point of the diploma thesis evaluate results.
