DOC/DPF+SCRIntegrated system

     In order to meet the six or 2010 U.S. emissions regulations, post-processing system will become more complex, need to oxidation catalysts (DOC), diesel particulate filter (DPF), selective catalytic reduction (SCR), and other integrated as a whole to control emissions. By putting a DOC/DPF and SCR, its passive and active regenerative can produce more control to oxidation and clean the filter, so as to remove particulate matter of more than 90%. After after system optimization and matching with the engine, DOC/DPF + SCR aftertreatment system will particulate matter and nitrogen oxides processing and dramatically reduce effectively at the same time, to meet the 6 and 2010 emissions standards in the United States.
