Product Name: Diesel Particulate Filter of Catalytic Converter Model NO.: DPF Deck: Single Muffler Type: Center Muffler Material: Carbon Fiber Type: Exhaust System Size: Produced as Your Requests Usage: Diesel Engine System Part Shape: Column Delivery Time: as Per Your Order Cell: 100-600cpsi Trademark: DXY Transport Package: Wooden Box + Pallet or Packaged as Customers' Need Origin: China HS Code: 84213990 Product Description Diesel Particulate Filter is one kind of wall flowed honeycomb ceramic filter with special structure and material. It is applied in the tail gas clean-up plant of diesel. It utilizes the pore of wall flowed filter to cut-off and catch the soot particulate in the tail gas of diesel and then purifies the tail gas. It is made by two materials: Cordierite and SiC.Characteristic: 1. Large and compact area per unit volume2. Small pressure loss and excellent capturing performance3. Excellent heat resistance and heat resistanceIf Diesel Particulate Filter (DPF) is coated with noble metal (such as Pt, Pd and Rh), the particulate of emission is captured inside thin gas hole or entrance. As it lasts, the cumulated layer become thick, and pressure loss increase. To ensure the performance of engine, when pressure loss reaches some value, it is a must to recycle the filter. The recycle is making the particulate burning, by raising the gas temperature of filer. The particulate condition is related to the oxygen concentration. Normally, it is buring at 550-650 celsius degree. Usually we raise emission temperature by adjusting throttle, and increase gas temperature with burner. The particulate burning temperature can be decreased by catelyzer, making cumulative particulate burning as soon as possible, thus recover the pressure loss and fitters performance, then the filter is recycled.Property (uncatalyzed)100/17200/12Cell densitycpsi100200cpscm15.531.0Wall thicknessinch0.0170.012mm0.4320.305Open frontal area (OFA), %34.534.5Geometric surface area (GSA)Inch 233.347.0m 2 /l1.311.85Hydraulic diameterInch0.0830.059mm2.111.49Modulus of rupture (psi/cpscm)350300Porosity (%)4848Coefficient of thermal expansion10 2 cm/cm/ (20-800) --maximum average55Mean pore size (micron)1313Melting temperature (celsius degree)14601460
