Diesel Particulate Filter is mainly used to produce new generation of diesel clean & emission system to fulfill the carbon particulate cleaning target of the Euro II, III, and IV 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.
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.
