Diesel Particulate Filter(DPF)
Diesel Particulate Filters are used in trap systems that remove particulate matter (soot) from diesel exhaust emissions. These filters have a cellular structure with individual channels open and pligged at opposite ends. Exhaust gases enter the open end, flow through the pores of the cell walls, and exit the filter through the adjacent channel. Sool particles are too large to flow through the pores, and they collect on the channel walls. Periodically the filter is regenerated (heated) to consume the soot and clean the filter.
