Abstract
In this research, a new type diesel particulate filter (DPF) using electric field was developed to remove soot particles exhausted from a diesel engine. This device is capable to trap soot particles by applying DC electric field between the electro-plates, and the soot particles were re-burned by the electrification through a bridge structure of accumulated soot particles. When lower voltage than Eg=200V was applied, the soot bridges were formed but they did not re-burned. When higher voltage (Eg>250V) was applied, the soot bridges re-burned actively. In the condition of Eg>250V, the developed device could be steady operated, and the soot removal efficiency was 60%‐80%. Also faster the gas velocity in the device, the re-burning at high voltage was more active compared with that at low voltage.
