Analysis of Zetor tractor output parameters with different gearbox design
Orság, Josef ; Škopán, Miroslav (referee) ; Bauer, František (advisor)
This thesis deals with energetical and efficiency comparison of two tractor transmission types, used by the Zetor company. The description of transmission construction types of various tractor producers is given, with focus on Zetor tractors transmission construction. The laboratory methodology and operating tractor and tractor sets measurement is described. The individual results are introduced in tables and graphs and subsequently evaluated.

Characteristic Piston Ring Failures and Their Corrective Methods
Orság, Josef ; Knotek, Jiří (referee) ; Raffai, Peter (advisor)
This Bachelor's thesis concerns the most common failures of piston rings. The first part of this thesis focuses on the design of a piston ring and on the load affecting it. The second part describes various kinds of lubrication. This section also shows, which lubrication states occur during operation of internal combustion engines. And final part is devoted to the most common failures of the piston rings and how to prevent them.
