提出了一种创新的柴油机排放总量控制系统，以同时降低柴油机颗粒物和NOx。在该系统中，等离子体反应器位于排放排气管的外部，并且由等离子体活化的臭氧诱导的活化气体被注入排气管中。另一方面，NOx还原是使用贫氧非热等离子体解吸实现的。氧的浓度可以通过控制发动机的焚烧状态或通过喷射贫氧气体来改变。对小型柴油发电机组的排放进行了试验研究，证明了其良好的性能。由于等离子体的周期性或间歇性应用，使用该系统可以进一步降低有效或表观所需的等离子体能量。在本研究中，实现了6.6 g/kWh的PM和16 g（NO2）/kWh的NOx的优异还原能量效率。
An innovative total diesel emission control system for diesel particulate and NOxsimultaneous reduction is proposed. In this system, the plasma reactor is located outside the emission exhaust pipe and activated gas induced from ozone activated by the plasma is injected into the exhaust pipe. On the other hand, the NOxreduction is achieved using oxygen-poor nonthermal plasma desorption. The concentration of oxygen can be changed either by controlling the incineration state of the engine or by injecting oxygen-poor gas. Experiments are carried out for the emission of small diesel engine generator and high performance is demonstrated. The effective or apparent required plasma energy can be decreased further using this system because of the periodic or intermittent application of the plasma. In the present study, the excellent reduction energy efficiencies of 6.6 g/kWh for PM and 16 g (NO2)/kWh for NOxare achieved.
