Cordierite Diesel Particulate Filter (DPF)
Product details
Cordierite Diesel Particulate Filter (DPF) is also called wall flow filter developed based on high quality cordierite material with excellent performance of high porosity, large specific surface area, low back pressure, small thermal expansion coefficient, good thermal shock resistance, etc., the special wall flow structure was used to effectively capture particulate matter from gasoline engine exhaust to reduce the NOx and PM / PN emissions. The catalytic oxidation of NO to NO2 through the catalyst coating assisted passive regeneration of Silicon Carbide diesel particulate filter (DPF). Forced controllable active regeneration also could be performed under the temperature supply conditions such as fuel injection combustion/ burner.
Cordierite Diesel Particulate Filters (DPF) adopt opening and blocking up passages in both ends and the exhaust gas flow through the porous beehive wall to filter particles, can effectively remove particulate matter (PM) and soot from diesel engine exhaust emission, the capture efficiency of OPM is more than 90%, and that of PN is more than 95%. Cordierite Diesel Particulate Filter (DPF) with excellent mass transfer and heat transfer performance and low cost, the catalyst coating is evenly distributed and stable, with low back pressure and good product consistency. Cordierite Diesel Particulate Filters (DPF) also with very low passive regeneration temperature, the equilibrium point temperature is below 320℃.
