Prostředky pro snižování emisí vznětových motorů
Andrýsek, Roman
This Bachelor thesis deals with the means enabling to eliminate the harmful emissions developed by diesel engines. The introductory part describes the individual components of emissions from combustion of diesel fuel. In connection with emissions from the combustion process, the legislative precautions are mentioned, which should define through their regulations the permitted amount of pollutants. Regarding the regulations, the existing devices complying with established limit values are described in the next part. As we can count on a more environmental friendly operation in the future, the final part of this thesis is focused on the operation of diesel-powered vehicles that can burn off much cleaner fuels than diesel oil. Specifically, it includes a gas fuel operation. Keywords: emissions, regulations, biofuels, fuel injection, EGR valve, particulate filter, oxidation catalytic converter, SCR catalytic converter, alternative fuels
