303 Development of Plasma-Assisted Aftertreatment System for Super Clean Diesel Engine : Recent Status Report

Abstract

Recently, the authors realized a new prototype of plasma-assisted environmental protection aftertreatment system using atmospheric-pressure nonthermal plasma combine processes for super clean diesel engines. This systems do not use any rare or precious metal catalysts and harmful ammonia or urea solution, and now at the stage of pilot-scale plants tests supported as a national supported program. In this report, recent status of the achievement is reviewed. The developed system demonstrates excellent energy efficiencies to meet the most recent Japanese national regulation of diesel engine exhaust gas.
