Control Systems of Gears Changing on Load in Tractors Gearboxes
Holub, Přemysl ; Svída, David (referee) ; Dundálek, Radim (advisor)
This bachelor thesis is interested in the overview of tractor’s gearboxes, which are changing on load. There are reasons, why it has to be costructed and there are requirements for it. There are also described PowerShifts, which allow us gear changing on load. After basic description of concrete gearbox, there is always some example of using in current tractors. In period named Mechanical gearboxes, wchich are changing partly on load there is more space for Zetor tractors and its gearboxes. In one of the last period there is important part about continuously variable transmissions where the driving speed is regulated steplessly. These gearboxes are considered to be modern technology of transfer engine torque.

The present state and development trends of engines for motorcycles
Peňáz, Jan ; Píštěk, Václav (referee) ; Rauscher, Jaroslav (advisor)
This bachelor thesis describes the actual situation of construction solutions of small motorcycles engines. And then this thesis compares power and economic parameters of these engines.The thesis shows watched parameters in the diagrams and in the tables. From this we deduce the direction which the small motorbikes engines take. In the conclusion we summarize the main development tendencies and trends for the future

Stanovení parametrů motocyklového motoru na válcovém dynamometru
Paráček, Marek
This diploma thesis focuses on the topic of engine and chassis dynamometers. Emphasis is given to historical development as well as current findings in this field, especially in field of motorcycle dynamometers. This diploma thesis also describes the motorcycle engine and its main structural parts. The practical part of this diploma thesis deals with measuring motorcycle parameters by using a chassis dynamometer. These parameters have been measured with various combinations of air filters and exhaust silencers. In the evaluation process, results based on measurements have been displayed as graphic dependences. The discussion part goes on and presents recommendations and proposals for the practical use of the motorcycle. These proposals and recommendations are based on measured values.

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.
