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
Diesel particulate filter can effectively remove black smoke(Pme.g. Hydrocarbons soot) from diesel engine exhaust emission, usually DPF removes 90% or more of the soot
Working Principle of Diesel Particulate Filter
By forcing the exhaust gases through the walls between the channels of the dpf, the particulate matter is deposited on the walls, so reducing the amount of air pollution
Regeneration of Diesel Particulate Filter
Bum the particulates by rising the gas temperature in filter to filtrate Pm which piled in the filter so as to guarantee the function of filter. The character of particulates in exhaust gas of diesel relates to concentration of oxygen. It will burn in temperature of 550-650.C.
