| Outline of Final Research Achievements |
The purpose of this study is to collect back carbon in diesel exhaust gases and improving energy efficiency. The experiments were carried out to collect the air born particles and diesel exhaust particles. As a result, the collection efficiency of 72% was achieved without the energy consumption at the gas velocity of 2.5 m/s in the case of collecting the air born particles. This cause may be due to natural charging of particles and increasing electric field intensity on the surface of particles. In the case of experiment for the diesel exhaust particles, the collection efficiency achieved 51% in the gas velocity of approximately 4 m/s without energy consumption.

| Academic Significance and Societal Importance of the Research Achievements |
大気中の浮遊粒子及びディーゼル排気微粒子を，エネルギーをほとんど消費することなく高電界のみで集塵できることを明らかにした点で，本研究成果の工学的意義は非常に大きい．また，消費エネルギーをほとんど消費することなく，大気塵を72%，ディーゼル排気微粒子を51%除去できたことは，CO2排出抑制，化石燃料の枯渇及び経済性の観点から社会的意義が極めて大きい．
