The Study of NOx Reduction Using Plasma-Assisted SCR Systems for a Heavy-Duty Diesel Engine

Event: JSAE Spring Conference
To reduce NOx emissions from a heavy-duty diesel engine at low temperature conditions, the effects of plasma-assisted selective catalytic reduction (SCR) systems were studied. Plasma-assisted SCR system was composed of NO oxidation catalyst, diesel particulate filter (DPF), ammonia injection system and plasma-assisted SCR catalyst. NOx reduction performance is improved by the plasma-assisted SCR system in low temperature conditions. In next stage it is necessary to evaluate for a durability of plasma-assisted SCR, to study for detailed measurements for un-regulated emissions from plasma reactor.
