The DPF and SCR systems
Novodomský, Tomáš ; Janoušek, Michal (referee) ; Dundálek, Radim (advisor)
The presented bachelor thesis deals with exhaust emission reducing systems for diesel engines. The first part is devoted to the composition of exhaust gases and emission standards. The thesis analyses the formation of solid particles, their regulation by the DPF system and its various variants. Further the principle of reducing the nitrogen oxide content in the exhaust gases by the selective catalytic reduction system is described. In the final part, there is a reflection on the future of emission reduction systems, emission standards and alternative drives.
