The Possibilities of Displacement Increase of 4C Zetor Engine
Zloch, Jan ; Franz, Rudolf (referee) ; Dundálek, Radim (advisor)
Diploma thesis aims on mechanical design of new concept of Zetor UŘ III engine with displacement increase and solves calculations of main and pin hydrodynamic bearings of crankshaft. Creo 2 CAD software is used for preparing mechanical design of this new concept. For computation and analysis of hydrodynamic bearings multibody model of crankshaft mechanism is used with flexible FEM model of crankshaft for solving dynamics of mechanism and performing hydrodynamic analysis of bearings in FEV Virtual Engine. Results of this diploma thesis demonstrate the feasibility of new concept of engine and serve as a basis for next engineering tasks before realization of concept.

Piston Rings of Modern Diesel Engines
Homola, Petr ; Knotek, Jiří (referee) ; Raffai, Peter (advisor)
This bachelor thesis concentrates on piston rings and is divided into several points. First point deals with the functions of piston rings and with the demands for them, in the second point there is a division according to the type of the ring and constructing solution. Another chapter deals with materials that are used the most when fabricating piston rings and the last chapter deals with the surfacing that is used the most.

Měření emisí pevných částic u vznětových motorů rozdílných emisních kategorií EURO
KAHUDA, Jan
This bachelor thesis deals with the issue of pollution of the environment by emissions of dust particles produced by engines of cars and also deals with the measurement of the concentration of dust particles emitted in the exhaust gases of diesel engines meeting the different EURO emission categories. Dust particles greatly pollute the environment and endanger human health as well as the lives of other animals and plants. The aim of this work was to find out the difference in the producing of dust particles in the exhaust gases of passenger car's diesel engines that meet the different emission EURO standards. Measurements were carried out using experimental preparation of own production - the measuring station. The dust particles concentration measurement was performed on four diesel engine passenger cars that meet the EURO 1, EURO 3, EURO 5 and EURO 6 emissions standards and while idling. The measuring device DUST TRAK 8530 from the TSI Incorporated company was used for measuring.
