Description and function
Diesel oxidation catalytic converter (DOC)
This exhaust after-treatment system is a closed system consisting of the
diesel oxidation catalytic converter A/B (DOC).
The diesel oxidation catalyst has a catalyzing surface, through which
harmful substances in the exhaust fumes are converted into non-harmful
substances. In the process, carbon monoxides and unburned
hydrocarbons are brought to react with oxygen and converted into carbon
dioxide and water. In addition, the nitrogen monoxides are converted into
nitrogen dioxides.
