大气压非平衡非热等离子体混合排气后处理系统，其不使用贵金属催化剂、有害氨等，是由作者开发的。两种类型的新的环保系统（干式系统和湿式系统），这使得生产超低，颗粒物和排放，以及减少燃料消耗和低成本，柴油发动机，船用发动机和燃烧锅炉的应用进行了研究。本文报道了干式系统的原理和最近的一些实验室试验结果。还原包括三个流动过程：1）吸附，2）加热，和3）冷却过程。加热过程对应于再生过程。这些过程按以下顺序重复：1）、2）和3）。该干式系统具有出色的能效，符合日本最新的汽车柴油发动机废气排放法规。在这项研究中，约60%的废气（：240 - 325 ppm，N：标准状态）可以处理35小时。实现了143的改进的系统能量效率，这是迄今为止最高的，用于减少。
Atmospheric-pressure nonequilibrium nonthermal plasma hybrid exhaust gas aftertreatment systems that do not utilize precious metal catalysts, harmful ammonia, etc., have been developed by the authors. Two types of new environmental protection systems (a dry system and a wet system), which enable the production of ultralow , particulate matter and emissions as well as reduced fuel consumption and low cost, are investigated for diesel engines, marine engines, and combustion boiler applications. This paper reports the principles of the dry system and some recent experimental results of laboratory tests. The reduction comprises three flow processes: 1) adsorption, 2) heating, and 3) cooling processes. The heating process corresponds to the regeneration process. These processes are repeated in the following order: 1), 2), and 3). This dry system demonstrates excellent energy efficiencies that meet the most recent Japanese national regulations regarding automobile diesel engine exhaust gas. In this study, approximately 60% of the of the exhaust (: 240 325 ppm, , N: standard state) can be treated for 35 h. An improved system energy efficiency of 143 , which is the highest yet, is achieved for reduction.
