Application of Solar Powered High Voltage Discharge Plasma for NOX Removal in Diesel Engine Exhaust

This paper proposes a compact electric discharge plasma source for controlling NOX emission in diesel engine\ud exhaust. Boost converter is used to boost to solar powered\ud battery voltage to 24V, further an automobile ignition coil was used to generate the high voltage pulse using fly-back\ud topology. This design is aimed at retrofitting the existing\ud catalytic converters with pulse assisted cleaning technique. In this paper we bring out a relative comparison of discharge plasma and plasma-adsorbent process at different gas flow rates. Activated alumina was used as adsorbent. The main emphasis is laid on the development of a compact pulse source from 12V battery, which is powered by the solar, for the removal of NOX from the filtered diesel engine exhaust
