This Silent Discharge type of DPF (Diesel Particulate Filter) has been studied for reducing PM (Particulate Mater), we call it "SDeDPF". This SDeDPF was applied a Metal Fiber Sheet (MFS) for discharge electrodes to reduce backpressure and to mix exhaust gas well in a discharging space. Usually, exhaust gas temperature of diesel engines is under 200 or 250℃ at normal city driving condition. Under that condition, generally PM is not bourn out in the normal ceramic DPF. This SDeDPF aims to remove PM chemically and electrically even at low exhaust gas temperature continuously. Finally, in the basic lab test result, 95% reduction of PM has been verified by SDeDPF with a special Turbulent Block for turbulent and slower velocity of exhaust gas, the most suitable gap between electrodes and an optimum total area of piled electrodes. Also, its pressure drop was almost same as usual ceramic DPF.
