SCR-Catalyzed Diesel Particulate Filter (SDPF)

SCR-Catalyzed Diesel Particulate Filters (SDPFs) filter particulate matter, convert them periodically, and reduce NOx in the exhaust gas.  Two important reactions are:

• Without NO2: Standard SCR

4 NH3 + 4 NO + O2 → 4 N2 + 6 H2O

• With NO2: Fast SCR

4 NH3 + 2 NO + 2 NO2 → 4 N2 + 6 H2O
