Piston for 77kW 4-stroke CI-engine
Štol, Michal ; Svída, David (referee) ; Dundálek, Radim (advisor)
Annotation Michal Štol Piston of 4-stroke supercharged diesel engine for passenger car ÚADI, 2008, 39 pages., 18 images. In this bachelor works we will focus on description of piston’s group mostly, with characteristic properties and sorts of production. Further, we will make basic design of piston with strenght control of critical piston intersections. Then we can make drawings of individual part of piston.

Hodnocení vlivu biopaliva na parametry vznětového motoru
Holý, Martin
The dissertation is dedicated to the utilization of alternative propellants in transport with concentration in biofuel. Firstly, the theoretical part is focused on the technical aspects of their utilization. In addition, fuel characteristics, conditions and options of their applications in diesel-powered vehicle engines are there characterized. The influence on production of exhaust emission is also mentioned and legislation is briefly summed up there. Secondly, the practical part contents the measurement of basic parameters to the classic-powered engine and the biofuel-powered engine in a tractor Zetor Forterra 9641. The whole measurement is carried out in vehicle laboratories in the Department of Technology and Automobile Transport of Mendel University in Brno. Moreover a detailed elaboration and the final evaluation of the measurement results are included in the second part of the dissertation.

Hodnocení parametrů vznětového motoru provozovaného na biopalivo
Tálský, Miloslav
This diploma thesis consists of an overview of biofuel for diesel engines For each of biofuels is a detailed description of their specific characteristics, manufacturing process and the characteristics of their combustion or diesel engine modification. The experi-mental part focuses on the basic parameters of engines operating on diesel fuel mixed with diesel fuel and RME. Tested by internal combustion engines were two tractor tur-bo-charged diesel engines that were designed to run on diesel. Results achieved in the engine combustion of the fuels were then compared with each other and evaluated. As evaluated from experimental measurement results, it occurs when using as mixed fuel, and so as RME to contribute to the negative torque reduction, performance and increa-sed fuel consumption.

Animované modely tepelných motorů
Honzl, Michal
The present diploma thesis "Animated models of heat engines" describes the design of an interactive application. The theoretical part deals with the classification of heat engines and their rotations. The result of the present diploma thesis is the new application "Animation of heat engines" designed in Flash programme. This application is focused on the basic function principle of four demonstrated engines. The present work also deals with assessing and comparison of real engines, their cuts, real models and animated engines.

Compare the effect of different types of biofuels (composition, manufacturer) for diesel engines for their performance and comparative consumption.
HOLÝ, Martin
This work deals with the issue of using liquid biofuels in transport. The first part concentrates on technical aspects of their use. It summarizes sources for producing biofuels, characterizes individual production technologies and states physical and chemical properties of their products, ways of distribution and ecological aspects of their uses. It also briefly describes the history of using biofuels in the Czech Republic. Further on, it describes a technological unit to produce FAME by the company PREOL, a.s., Lovosice. Finally, it summarizes the existing range of biofuels used in transport in the Czech Republic. The second part contains experimental measuring on the motor brake of tractor Zetor 6211 in workshops of Agricultural faculty of South Bohemia University in České Budějovice and its processing with measurement evaluation.
