The collection of low resistive particulates generated from marine diesel engine had been known to be difficult using the conventional electrostatic precipitators. The electrohydrodynamically-assisted electrostatic precipitator (EHD ESP) was developed to suppress the particle reentrainment. A nobel NOx reduction system, which consists of adsorption, desorption, followed by nonthermal nitrogen plasma was developed. In addition, the plasma ESP, which is able to collect and incinerate particles within the same unit. Furthermore, reactive species injection for PM reduction and NOx recirculation EGR system were developed. Those technologies were integrated to achieve more than 90% PM and NOx reduction, leading to extremely economical and compact marineengine emission control.

众所周知，使用传统的静电除尘器很难收集船用柴油发动机产生的低电阻颗粒。开发了电流体动力辅助静电除尘器（EHD ESP）来抑制颗粒再夹带。开发了一种诺贝尔氮氧化物还原系统，该系统包括吸附、解吸和低温氮等离子体。此外，等离子 ESP 能够在同一装置内收集和焚烧颗粒。此外，还开发了用于减少 PM 的活性物质喷射和 NOx 再循环 EGR 系统。这些技术相结合，可实现 90% 以上的颗粒物和氮氧化物减排，从而实现极其经济且紧凑的船用发动机排放控制。
