Control Strategy for NOx- Emission Reduction with SCR

Future emission standards for heavy-duty vehicles like Euro 4, Euro 5, US 7 require advanced engine functionality. One contribution to achieve this target is the catalytic reduction of nitrogen oxides by injection of urea water solution to the exhaust gas. An overview on a urea dosing system, also c...

Zusammenfassung:Future emission standards for heavy-duty vehicles like Euro 4, Euro 5, US 7 require advanced engine functionality. One contribution to achieve this target is the catalytic reduction of nitrogen oxides by injection of urea water solution to the exhaust gas. An overview on a urea dosing system, also called DENOXTRONIC, is given and a dosing strategy is described.
