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.
