摘要
通过建立低温等离子体(NTP)喷射系统试验台架,研究了NTP反应器产生的活性物质对柴油机HC,NOx,PM排放的转化效果,并研究了对DPF的再生效果。研究结果表明:当柴油机在低速小负荷工况运行时,排气温度较低,NTP反应器产生的O3,O等活性物质主要将柴油机NOx排放物中的NO部分氧化为NO2;当柴油机高速大负荷工况运行时,活性物质对排气中HC,PM的氧化作用加强,将额外生成CO,同时实现对DPF的连续再生。
The test bench of non-thermal plasma injection system was built to study the influence of active substance, which was produced by non-thermal plasma reactor, on HC, NOx and PM emission. And the regression effects of DPF were also re- searched. The results show that the active substances like O3 and O, which are produced by NTP reactor, mainly oxidize NO to NOx partially due to low exhaust temperature at low speed and low load and strengthen the oxidization of HC and PM, which results in the additional formation of CO, and realize the continuous regression of DPF at high speed and high load.
