Diesel Particulate Filter adopts structure of honeycomb. It sets up independent opening and blocking up passages in both ends and the waste gas enters from one open end, then goes through the porous beehive wall, and finally discharges from adjoining passage. The carbon particulates are left over on passage wall because they are too big to pass through wall hole and won't be discharged to air.
Diesel particulate filter is also called Diesel Particulate Filter (DPF). The main composition of tail gas discharge from diesel is carbon particulates. Diesel particulate filter is a setting to reduce emission granule by filtrating which is set in exhaust system in diesel. Its efficiency for carbon particulates filtration is more than 90%. Part of dissoluble organic composition (SOF) (especially high boiling point) may be trapped. The filtration material researched and used in China at present is of three types: Ceramic, metallic and composite based.
Sic-based Diesel Particulate Filter is a high-tech product. It is mainly used to produce new generation of diesel clean & emission system to fulfill the carbon particulate cleaning target of the EUIII, EUIV standards working principle for Sic-based Diesel Particulate Filter: It can reduce 96.5% carbon particulates emission by holding up the carbon particulates in tail gas of diesel at first, then clear up carbon particulates by means of electric heat, fuel burner etc., finally to meet carbon particulate emission standards.
Silicon carbide filter cores also look like catalytic converter cores that have had alternate channels plugged - again the plugs force the exhaust gas flow through the wall and the particulate collects on the inlet face.
*Excellent capturing performance
*Small exhaust back pressure
*Nice corrosion resistance to oil, ash, and engine scouring
*Excellent heat resistance and thermal shock resistance.
*Lower thermal expansion
A diesel particulate filter removes particulate matter from diesel exhaust by physical filtration. The common type is a ceramic (cordierite or silicon carbide) honeycomb substrate. The structure like an emissions catalyst substrate with the channels blocked at alternate ends. The exhaust gasses must therefore flow through the walls between the channels and the particulate matter is deposited on the walls. Other filter types are available, using sintered metal plates, foamed metal structures, fibre mats and other materials as the filtration medium.
