Application of plain bearings for four-stroke internal combustion engines
Šedo, Matej ; Janoušek, Michal (referee) ; Drápal, Lubomír (advisor)
Subject of this thesis are plain bearings and especially their application for four-stroke internal combustion engines. Thesis is divided into two main parts. The first part provides a basic description of plain bearings, their distribution and evolution. It also discusses their materials and the theory of hydrodynamic lubrication. The second part covers concept of sliding bearings in internal combustion engines and their load associated with the election of right material. It also includes description of particular application of plain bearings and the method of oil distribution. It handles the mounting of crankshaft and camshaft, piston pin, connecting rod and other places where sleeve bearings are use.

Eccentric Cranktrain
Kóňa, Marián ; Janoušek, Michal (referee) ; Drápal, Lubomír (advisor)
This thesis is focused on design of four-stroke engine eccentric cranktrain. The thesis includes kinematic analysis of mechanism. The main attention is paid to examination of dynamic variables which burden piston skirt. Result of the thesis is designed eccentricity value of mechanism to reduce piston skirt stress.

Porting and cylinder scavenging of two-stroke engines
Havlen, Prokop ; Svída, David (referee) ; Drápal, Lubomír (advisor)
In the first part of this thesis are explained, main calculations for two-stroke engine cylinder, channels and combustion chamber. In the second part are described in more detail systems scavenging of cylinders. This section is an attempt to compare them with each other and evaluate their advantages and disadvantages. Many of these systems have not spread. They are listed as other possible constructions.

Aircraft Engines till the End of WWII
Falta, Libor ; Drápal, Lubomír (referee) ; Dundálek, Radim (advisor)
Bachelor’s thesis deals with aircraft piston engines until end Second World War. Thesis surveys about known, the most use and non-traditional types of engines in timeline. At the beginning it deals about history of aviation and the first use of piston engine as power source energy for controlled flight. There are high requirements on aircraft piston engines. Improving construction and increasing output of engines. In every chapter typical construction and the most powerful engines of the period are described. Thesis includes influence of both World Wars and some prestigious racings, which considerably accelerated global development. Explain the limit for increase output of piston aircraft engines in the last part.
