要約(日本語): Newly developed electrostatic diesel particulate matter filtration system (DPS) has been tested using 3000 cc diesel engines with an engine dynamo at stead-state (idle, 2000 rpm, 2000 rpm 25/ 50% load, 3000 rpm/ 50% load and 3500 rpm/ 60% load) and standard (European Stationary Cycle 13 mode) engine operational conditions. The system consisted of an ionization section, electrostatic field additional section and flow through filter (FTF), and the high voltage electrode inserted in the ionization section was electrically insulated using air insulation device in order to maintain stable corona discharge under high exhaust temperature over 300oC at the high speed and load conditions. At the stead-state engine conditions, the performance test of the DPS showed a high removal performance (nearly 80 - 90%) at the engine operation conditions, while the efficiency of FTF was maintained at 15 - 50%. Comparing the performance of the DPS with a commercialized Diesel Particulate Filter (DPF) and a FTF under the standard test mode, the ESC 13 mode, the DPS achieved almost 40% higher removal efficiency than the FTF, and 10% less removal efficiency than the DPF, and it also achieved 55% lower pressure drop than the FTF and 73% lower than the DPF. It is concluded that the novel ESP to remove ultrafine diesel PMs could achieve almost similar removal performance to the DPF with significantly less pressure drop than the DPF.
