Stage IV Emission Standards for Tractor Engines
Vít, Jakub ; Beran, Martin (referee) ; Dundálek, Radim (advisor)
The aim of this bachelor thesis is to explain the mechanism of injection of carbamide and its installation on a vehicle. The first part of this work deals with the reduction of pollutants in the exhaust gases and with the emissions standards which limit the level of pollutants in the exhaust gases. The second part consists of an overview of tractor brands available at Czech market and their classification based on the type of system they use on their new models to reduce the pollutants in the exhaust gases.

Emission Levels for Tractor Engines
Vaško, Roman ; Beran, Martin (referee) ; Dundálek, Radim (advisor)
This bachelor’s thesis deals with the emission standards of tractor engines. There is a tightening of standards in recent year generally. The former part of the thesis contains description of specific pollutants that are exhaled into the air. The second part is focused on newly presented Tier 4i standards (Stage IV). The third part includes technologies, which provide engines to meet new regulations. The last chapters deal with an overview of the largest manufacturers of tractors, including Zetor, and their approach to emissions.

Turbochargers regulation
Staněk, Lukáš ; Beran, Martin (referee) ; Vančura, Jan (advisor)
The bachelor’s thesis outlines the problem of using the controls of turbochargers regulation in the development and tetsting in the laboratories. The main task is to acquaint the readers with basic pneumatic, mechanical – pneumatic and pneumatical – electronic systems VNT ( Variable Nozzle Turbine) and WG ( Waste gate) turbochargers. Another point of this thesis is to clarify the involvement of a system of monitoring and control elements of the REA (Rotary electric actuators) systems on the turbochargers when tested in a cell or the REA stress tests on a strong base.
