Abstract

An efficient NO x reduction aftertreatment technology for a marine diesel engine that combines nonthermal plasma (NTP) and NO x adsorption/desorption is investigated. The aftertreatment technology can also treat particulate matter using a diesel particulate filter and regenerate it via NTP-induced ozone. In this study, the NO x reduction energy efficiency is investigated. The investigated marine diesel engine generates 1 MW of output power at 100% engine load. NO x reduction is performed by repeating adsorption/desorption processes with NO x adsorbents and NO x reduction using NTP. Considering practical use, experiments are performed for a larger number of cycles compared with our previous study; the amount of adsorbent used is 80 kg. The relationship between the mass of desorbed NO x and the energy efficiency of NO x reduction via NTP is established. This aftertreatment has a high reduction efficiency of 71% via NTP and a high energy efficiency of 115 g(NO 2 )/kWh for a discharge power of 12.0 kW.
