Diesel Particulate Filters and Various Types of their Regeneration
Štěpánek, Josef ; Svída, David (referee) ; Dundálek, Radim (advisor)
This work deals about creation particulate matter and their impact on health. It focused on diesel particulate filters and various types of their regeneration. Differences of various designs and producers of diesel particulate filter are introduced in this work.
An aftertreatment system for the passenger vehicles with a diesel engine
Stráník, Daniel ; Šebela, Kamil (referee) ; Böhm, Michael (advisor)
This bachelor thesis deals with the issue of emission systems of diesel engines. The aim of this work is to analyse these systems, describe their construction and their controlling, explain the function, and determine their effect on the individual components of exhaust gases and average fuel consumption. The work also contains own concept of aftertreatment.
Research of Progressive Methods for Reduction of Emissions in CI Engine Exhaust Gasses
Franz, Rudolf ; Děrgl, Martin (referee) ; Stodola, Jiří (referee) ; Novotný, Pavel (advisor)
The scope of this dissertation work is a description of modern methods of reducing exhaust emission in diesel engines. The fundamental part is the application of these methods for diesel engines for off-road use that means for engines that are used in tractors and road machines. The mentioned evidence for the practical utility of the results of this dissertation thesis in practice and their verification on the actual engine are given in the conclusion.
Stress-strain Analysis of Diesel Particulate Filter Support on Tractor Zetor Forterra
Kučera, Petr ; Ramík, Pavel (referee) ; Dundálek, Radim (advisor)
The subject of this master's thesis is the FEM analysis of the construction of the diesel particulate filter support on the tractor Zetor Forterra. The introduction of this thesis is about the theoretical part dealing with the issue of emissions from diesel engines and ways to reduce them. The following part describing the creation of the computational model. Then, the static stress-strain analysis, modal analysis and fatigue analysis are solved in the ANSYS Workbench software. The assessment of the safety of the structure in terms of limit states, that may occur during the operation of the tractor, based on the results of calculations is in the conclusion of the thesis.
Catalytic converter and particulate filter functions on diesel vehicles
Šišpera, Adam ; Beran, Martin (referee) ; Bazala, Jiří (advisor)
Tato bakalářská práce se zabývá představením dieselových emisně-redukčních systémů široké veřejnosti, odkrývá základní principy funkce dieselova motoru, mechanismy vzniku emisí a následně se věnuje jejich regulaci za pomocí katalytické redukce a filtru pevných částic. Odhaluje, proč je provozní teplota pro funkčnost těchto systémů klíčová a prezentuje možnosti, jak ji regulovat. V závěru pojednává o možnostech snížení uhlíkové stopy a vyhovění nadcházející emisní normě EURO VII.
Unit Injectors
Cihlář, Lukáš ; Drápal, Lubomír (referee) ; Dundálek, Radim (advisor)
This bachelor’s thesis deals with the description of unit-injector system. Injection system used in passenger cars as well as Unit-Pump-System used in trucks is described. One chapter deals with general problems of emissions, including description systems of the reduction exhaust gases. In the end is the practical application of the system in the engines of the Volkswagen Group.
Stress-strain Analysis of Diesel Particulate Filter Support on Tractor
Ježek, Přemysl ; Ramík, Pavel (referee) ; Dundálek, Radim (advisor)
The subject of this thesis is to carry out stress-strain analysis of diesel particulate filter support on tractor. So it describes sequence of steps for the analysis model, such as geometry description, mesh generation, applied forces definition and others. Result of the analysis is assessed in terms of strength and improvement was proposed.
Engines of Octavia vehicles
