Possibilities of 2-cylinder Engine Balancing for Tractor Usage
Vaško, Roman ; Franz, Rudolf (referee) ; Dundálek, Radim (advisor)
This thesis deals with possibilities of 2-cylinder engine balancing for tractor usage. The purpose of this thesis is to find a technical solution for the creation of the concept of balancing using balancing shaft. Check the proposed solution by FEM analysis and evaluate the fatigue safety. The content of the thesis is the creation of computational and graphical documentation too.

Injection System Build-in on Tractor Engine
Svršek, Michal ; Ramík, Pavel (referee) ; Dundálek, Radim (advisor)
The aim of this work is to design the installation of a new injection system to the existing tractor engines and construct new components necessary for proper function of the injection. In the following section is suggesting the location of other accessories for engine control. This is an injection system with a pressure reservoir "Common Rail" and all its components are created in modeling environment PTC Creo 2.0. Designed components are tested for strength and they are subjected to modal analysis.

Common Rail for Six-cylinder CI Engine
Božik, Michal ; Ramík, Pavel (referee) ; Dundálek, Radim (advisor)
This thesis deals with the installation of high-pressure common rail injection system for six-cylinder tractor diesel engine. In the first part of the thesis is dismantled issue injection systems and related aspects. The next part is the installation of a fuel injection system, which involves placing components common rail system, the implementation of necessary interventions in engine design and the design of new components. The final section effect control calculations and stress analysis of new injection system components.

Common Rail for Four-cylinder CI Engine
Brhel, Štěpán ; Svída, David (referee) ; Dundálek, Radim (advisor)
This master´s thesis deals with instalation of high pressure injection system Common Rail on four-cylinder tractor CI engine. Thesis introduces in the first part the injection systems of CI and tractor engines and related issues. In the next part is solved the conversion of engine, design of most important components - injetor, high pressure pump, pressure accumulator and high-pressure pipes and then stress analysis of new components.

Common Rail System for 6-cylinder Tractor Engine
Černoch, Josef ; Ramík, Pavel (referee) ; Dundálek, Radim (advisor)
This thesis deals with the installation of modern high pressure injection common rail system to six-cylinder tractor engine. This system replaces injection system with in-line fuel injection pump. Common Rail system installation on an existing engine is designed with minimal design changes to the engine block and engine head. It is advantageous to minimize production costs of the transition to high-pressure injection system. The thesis contains the design and stress analysis of the new component for high-pressure injection system.

Vyhodnocení emisí traktorového vznětového motoru
Tunka, Lukáš
Although combustion engines are not occupying the first place of environmental polluters globally, from the local perspective they are undoubtedly the most important. That is why their side environmental effects are very closely monitored and there is an increasing pressure to minimize them. The issue of pollutants in exhaust gases is discussed in this diploma thesis, which is focused on diesel tractor engine. Theoretical part includes a detailed analysis of emissions of diesel engines, discusses European emission limits of tractor's engines and possible design of technical devices to reduce pollutants in exhaust gases. Experimental part deals with evaluation of influence of shape of combustion chamber on emissions of a diesel engine Zetor Z1605. This part also includes a detailed description of measurement methodology, NRCS cycle and used measuring devices. The measurement was performed at the workplace of Research and Development of Zetor Tractors a.s. company.
