The passive DPF regenerations by means of catalytically coated DPF's (CSF ... catalyzed soot filter), or a combination of oxidation catalyst (DOC) upstream and a CSF downstream are preferred for retrofitting as simplest solution, if the conditions of engine operation allows it. Especially the engine application has to result in sufficient frequency of higher exhaust gas temperatures, which enable the light-off and sufficient duration of the catalytic oxidation of the collected particle mass.
To regenerate these systems and avoid damaging excess pressure, due to clogged pathways, a certain temperature is needed to activate the catalytic surface of the monolith structures (known as coated DPF or CSF - catalyzed soot filter). The particles get burned at relative low temperatures (350 - 500 °C / 660 - 930 °F), regarding to the temperatures needed without the help of a catalytic compound (more than 600 °C / 1110 °F). The pores are relieved of the soot and particulate matter, carbon dioxide and nitrogen monoxide leave the exhaust pipe. This happens permanently and is known as 'Continuously Regenerating Trap'concept (CRT)
Function:
Wall-flow diesel particulate filters usually remove 95% or more of the soot, and under certain conditions can attain soot removal efficiencies approaching 100%
Working Principle
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.
