摘　　要：利用低温等离子体技术转化柴油机NOX很大程度上取决于排气中的气体成分以及等离子体的放电能量,放电过程直接影响气体分子的电子冲击分裂。为此,分析了利用低温等离子体技术处理柴油机NOX排放可能发生的转化反应及其影响因素;并通过介质阻挡放电,研究了放电电压、放电频率与放电功率、功率因数之间的关系,分析了这些因素对处理NOX排放的影响。结果表明,放电功率是等离子体处理氮氧化物最直接的影响因素。Treatment of NOx through non-thermal plasma greatly depends on exhaust components and discharge power, because discharge has effect on molecule split through electron impact. The reaction mechanism and the infection factor of NTP technology for the removal of NOx in diesel exhaust were given in this paper. The relations between voltage, discharge frequency, electric power and power-factor were analyzed through dielectric barrier discharge, and their effect on removal of NOx was presented. Discharge power is the most direct bisection factor of the removal of NOx by non-thermal Plasma technology.
