Technology of Selective Catalytic Reduction for Passenger Cars
Jurík, Juraj ; Janoušek, Michal (referee) ; Dundálek, Radim (advisor)
This bachelor’s thesis describes the selective catalytic reduction technology. It concerned of reducing nitrogen oxides in diesel engines. It describes components of the technology, their function and location in system. in first chapter there are described harmful substances of exhaust gas in connection with this technology. Second chapter contains description of emission standards. Next chapters are describing selective catalytic reduction and solutions of some manufacturers.

Optimization of Bosch DNOX 5.x Pump Module Testing Matrix
Friedl, Michal ; De Bernardi, Olivier (referee) ; Dundálek, Radim (advisor)
Táto diplomová práca sa zaoberá optimalizáciou validačných testov pre produkt firmy Robert Bosch určený na úpravu výfukových plynov vznetových motorov, tzv. Denoxtronic 5.x, konkrétne jeho najkomplikovanejšiu časť – Pump Module. Zhrnutím a analyzovaním porúch objavujúcich sa v reálnej prevádzke tak poskytuje spätnú väzbu pre oddelenie vývoja a navrhuje, akým mechanizmom by mali byť v budúcnosti validačné testy optimalizované.

Vliv jízdního režimu nákladního vozidla na spotřebu vodného roztoku močoviny v systému selektivní katalytické redukce
Marek, Vít
This thesis titled Impact of driving mode on urea consumption describes the influence between different drive modes and conditions of urea injection into the selective catalytic reduction system. The first half of the thesis deals with the theoretical part. Introduction deals with the theory of formation of harmful pollution in exhaust emissions, the effects of pollutants and legislative regulations. There are also explained key parts of different systems, reduction of harmful exhaust gas components . The main emphasis is put on the selective catalytic reduction. Other chapters are devoted to the methodology and testing procedures . The aim of this thesis is a presentation of the system regulation, its pros and cons under various operational modes.
