Fundamental study on DPF utilized with electric field

Abstract

The environmental destruction by the exhaust gas from diesel engine is the most major cause for air pollution. Therefore, many solution methods have been studied. That major solution is DPF (Diesel Particulate filter). However developed devices cannot capture smaller particle than 1μm in exhaust gas. Then, electric field was applied in this research. Particles were captured by input of Direct current to electrode plates. Its characteristic showed that the increasing of voltage made much captured particles. By distance spreading between electrode plates with constant electric field, the effect of electrode on capture decreased slightly. When input voltage changed to Alternating current, particles cannot be captured over 100Hz
