Diesel engine exhaust gas-purifying catalyst (DOC+DPF) [Sep 25,2014]
Diesel engine exhaust gas-purifying catalyst (DOC+DPF)

Introduction:
The main component of diesel engine exhaust gas purification catalyst (DPF catalyst ) of the basic metal compound Panasonic R & D , can be directly oxidized and decomposed in the diesel engine exhaust particulate matter (PM). Compared to the conventional platinum catalyst , since the NOx catalyst without passing through the DOC conversion NO2, thus reducing the amount of expensive platinum , lower cost , and can obtain the same decomposition performance at lower temperatures, and in temperature can be increased at the same rate of decomposition .
Use of the catalyst can also improve the combustion performance to the number of PM 's calculations , can reach more than 90% removal efficiency . In addition , the use of the present catalyst can also be a diesel engine exhaust gas treatment apparatus to reduce the cost and energy efficiency .
 
Summary:
The heat-resistant ceramic surface coated with the catalyst, the catalyst of the DPF arranged on the downstream of the DOC , the exhaust gas can be removed in the formation of PM in diesel engine exhaust gas treatment device .
