Diesel Oxidation Catalyst for CO and Unburned Hydrocarbons Removal from Diesel Exhaust Under Plasma Discharge Conditions
Résumé
The use of non-thermal plasma for the improvement of diesel Oxidation Catalyst performance was investigated. Instantaneous concentration and cumulative mass of regulated gaseous emissions derived from simulated diesel engine exhaust (CO, HC, NOx) have been studied in test bench for both steady-state conditions and during the New European Driving Cycle (NEDC). The combination of the DOC downstream the plasma reactor decreases the catalyst light-off temperature and the CO and HC emissions.
