This article is intended to provide a comprehensive review of the experimental studies conducted to understand the effect of several parameters involved in the discharge plasma-based nitrogen oxides (NOX) removal from real diesel engine exhausts, be it stationary or automobile, in addition to simulated ones. In the last two decades, much progress has occurred in the electric discharge-based nonthermal plasma (NTP) treatment of exhaust gas with or without cascading any additional treatment technique, such as catalysts or adsorbents. Most of these studies were conducted with the aim of enhancing the removal of NOX or studying the efficacy of a particular parameter on NOX removal or both. It is now timely to collage the findings of these studies in a way to help the present researchers to understand the effect of various parameters/measures associated with stand-alone and cascaded NTP treatments for NOX removal. It is also intended that the current review helps in moving closer to realizing the application of NTP in the cleansing of gaseous pollutants of diesel exhaust.

柴油机排气中NO X 的放电等离子体处理综述：单机和级联措施的进展


本文旨在对实验研究进行全面回顾，以了解放电等离子体基氮氧化物 (NOX) 从真实柴油发动机废气中去除所涉及的几个参数的影响，无论是固定式柴油机还是汽车柴油机，以及模拟数据。那些。在过去的二十年中，在使用或不使用任何附加处理技术（例如催化剂或吸附剂）的情况下，基于放电的非热等离子体（NTP）废气处理取得了很大进展。大多数这些研究的目的是增强氮氧化物的去除率或研究特定参数对氮氧化物去除率的功效，或两者兼而有之。现在是时候将这些研究的结果进行整合，以帮助目前的研究人员了解与独立和级联 NTP 处理去除 NOX 相关的各种参数/措施的效果。目前的审查还旨在帮助更接近实现NTP在柴油机尾气气态污染物净化中的应用。
