Product Description High Performance Doc+DPF Diesel Particulate Filter for CarThis product can be directly oxidized and decomposed 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. It can also improve the combustion performance to the number of PM 's calculations , can reach more than 90% removal efficiency. Sanhe DPF and DOC units are proudly designed and manufactured , backed by outstanding warranty coverage and meet all Euro emissions standards. Schematic Diagram For Analysis of Filtering Efficiency of Principle StructureFeatures:Easy Installation. Exceptional Durability. Optimum Performance.Ceramic DOC technology with Zeolites designed to extend the performance of diesel catalytic converters into the low temperature rangeMaintenance-free, reliable and cost-effective emission control solutionAvailable in both universal and direct-fit designs Mufflers are built entirely from corrosion resistant materials: aluminized and stainless steelsInstallation time and cost are reduced to a minimumDOC Catalytic Mufflers match or surpass the original muffler in sound attenuation and back pressure characteristics with addition of superior emissions performanceGreat at reducing deadly emissions,such as Carbon Monoxide(CO) and Hydrocarbons(HC)The Catalyst Substrate of DPF Particulate Capture:The catalyst substrate of DPF particle filter is a wall-flow honeycomb ceramic with cordierite or silicon carbide as raw materials. The main component of exhaust gas excluded by diesel engine is carbon particles. DPF particle trap is installed in the exhaust system of diesel engine. A device for reducing particulate matter in exhaust gas by filtration has a filtration efficiency of over 90% for carbon particles. Working Principle: The holes of honeycomb porous ceramics are blocked alternately, and the wall holes of ceramics are used to filter and remove particulates.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.Parameters:Property (uncatalyzed) 100/17200/12Cell densitycpsi100200cpscm15.531.0Wall thicknessinch 0.0170.012mm0.4320.305Open 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)14601460Dimensions:RacetrackRotundityΦ169±x85.7±1x127±1 R30Φ150x100Φ148±1x82±1x127±1 R38Φ150x75Φ144.8±1x81.3±1x76.2±1 R37Φ125x130Φ144.8±1x81.3±1x75±1 R37Φ144x152Φ127±1x61±1x120.7±1 R23Φ118x152Φ145x80x80Φ106x150Φ93±1x61±1x90±1 R30Φ106x100Φ120.6±1x80±1x50.8±1 R39.6Φ103x100Φ120x80x75Φ101.6x100Φ147±1x95±1x70±1 R36.6Φ100x100Φ100x100x75Φ93x130Φ50x50x25Φ93x49.85Diesel Oxidation Catalyst(DOC) Three-Way Catalytic Filter:When the high temperature automobile exhaust passes through the purification device, the purifier in the three-way catalytic converter will enhance the activity of CO, HC and NOx gases and promote their oxidation-reduction chemical reactions. Among them, CO is oxidized to colorless and non-toxic carbon dioxide at high temperature. HC compounds are oxidized to water (H20) and carbon dioxide at high temperature. NOx is reduced to nitrogen and oxygen. Three kinds of harmful gases become harmless gases, so that the automobile exhaust can be purified.We can make customized catalytic converter to meet customers' demand.
