Abstract
Diesel Particulate Filter (DPF) is studied as an effective method for removing PM in exhaust gas from the diesel engine. However, it is not possible that DPF removes very small PM which is noxious for the human body, from its principle. Our goal of this study is the development of scrubber system which can remove small PM. In the current stage, the conclusion of this paper that 53% of PM which has passed DPF could be removed is got.
