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.

船舶柴油机排放的低阻颗粒物难以用传统的静电除尘器进行捕集。电液动力辅助静电除尘器（EHD ESP）是为了抑制颗粒二次夹带而开发的。开发了一种由吸附、脱附和低温氮等离子体组成的氮氧化物还原系统。此外，等离子体ESP能够在同一单元内收集和焚烧颗粒。在此基础上，开发了用于减少颗粒物排放的活性组分喷射和NOx再循环EGR系统。这些技术的集成实现了90%以上的PM和NOx减少，从而实现了极其经济和紧凑的船用发动机排放控制。
