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.

Piston Modification for Suzuki Swift 1,3 GTi 4-stroke SI-engine
Bastl, Ondřej ; Blaťák, Ondřej (referee) ; Svída, David (advisor)
This bachelor’s thesis is engaged in a piston modification of engine type G13B of vehicle Suzuki Swift 1.3 GTi. The aim of my work is to perform changes of some dimensions of the piston, while complying with some of the main dimension, to increase its stress resistance and the engine’s power. Strength calculation for the piston to last during the whole service life of the engine is an indispensable part of this work.

Reduction of cranktrain mechanical losses
Lhota, Martin ; Píštěk, Václav (referee) ; Novotný, Pavel (advisor)
The aim of the bachelor thesis Reduction of cranktrain mechanical losses is to describe the issue of lowering mechanical losses occuring in the crank mechanism of internal-combustion engine. Therefore it aims to create a list of mechanical losses main sources, to show suitable methods to determine them, and to describe some of earlier used concepts leading to reduction of friction losses. Further, it is focused on the description and comparison of existing trends by which the given problem can be solved to a certain extent. The thesis also tries to evaluate these trends by an analysis following the standpoint of effectiveness and progressiveness, and to formulate a conclusion.

Piston for 80kW 4-stroke CI-engine
Vostrejž, Jan ; Dundálek, Radim (referee) ; Svída, David (advisor)
This bachelor thesis deals with a piston design for a four-stroke spark-ignition engine with the power of 80kW. The aim of this thesis is to determine main proportions of the engine, the piston, the crank mechanism and to perform a solidity check of the critical piston crosscuts. The thesis also contains a design documentation of the piston for the spark-ignition engine.

Piston for 50kW 4-stroke SI-engine
Spáčil, Tomáš ; Dundálek, Radim (referee) ; Svída, David (advisor)
This bachelor thesis deals with a primary proportions calculation design of the engine and a constructional piston design for four-stroke spark-ignition engine. It is also contains a design of crank mechanism and engine primary proportions. On the basis of empirical data I projected the piston primary proportions. Furthermore, this thesis deals with the solidity check of critical piston crosscuts according to the crank mechanism.

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 VW TDI 81kW Engine
Skoupý, Petr ; Dundálek, Radim (referee) ; Svída, David (advisor)
The bachelor‘s work deal with proposal piston for VW TDI 81 kW engine. Aim this work is determine principal dimensions of the engine, the crank mechanism and piston. At the beginning are describes a parts of the engine and then there the piston assembly. Further there is a work deal constructional design and material of piston. In a last way too strenght calculation of critical piston cross-sections.

Adjustable crank mechanism for shock absorber testing rig.
Podhorský, Petr ; Číž, Petr (referee) ; Mazůrek, Ivan (advisor)
This bechelor thesis deals with redesing of the mechanical shock absorber tester, which is situated in laboratory of designed department. First part focuses on the principle of shock absorbers and division. Next is something about devices, which are used to testing the shock absorbers. Because these equipments are a wealth of species, work is focusing on the devices, which tests excluded shock absorber only. The next part describes a few variants reconstruction of referenced tester. After that is chosen variant, which is the most simple, economic and production simple. This variant is after that numerically checked. In the end is educt, which describe the tester redesign.

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.
