Development of Efficient Diesel Particulate Filter System Using AgPd-Catalyst for Euro6 Regulation

Abstract

Efficient Diesel Particulate Filter system with low CO₂ emissions and low cost has been realized and applied for new diesel engines meeting the Euro6 regulation. PM oxidation performance was improved by AgPd-catalyst coated onto the filter surface. At the same time, the maximum soot amount was maintained by the high heat resistance and stability of the catalyst. To combine with a NOx storage catalyst system, the DPF system can also provide H₂S removal.
