低温等离子体对柴油机颗粒物理化性能的影响
Effect on the physical and chemical characteristics of diesel particulate matter by the NTP technology
通过台架试验，研究了温度对NTP处理柴油机碳烟排放的影响。利用气相色谱-质谱联用仪（GC-MS），检测了NTP处理后颗粒物样品中的SOF组分变化。结合热失重分析仪（TGA），分析了NTP对颗粒物样品组分及热重特性和碳烟起燃温度的影响。结果表明，碳烟排放随温度的升高而降低。NTP处理后，碳烟排放降低较多；NTP处理前后，颗粒物样品中SOF成分的质量分数分别为31.12%和24.36%。在25℃~1000℃温度范围内，NTP处理前后颗粒物样品的总失重率分别为95.63%和94.89%，同时NTP处理后颗粒物样品放热峰温度降低67.5℃。
Based upon the bench test, the effect of the temperature on the treatment of diesel soot emissions by the NTP technology was investigated. The SOF components of PM samples before and after NTP treatment were tested with GC-MS analysis. The effect of NTP on the thermo-gravimetric characteristics of PM and the ignition temperature of soot were analyzed with TGA analysis. The results showed that the soot emission decreased with the temperature, and was more decreased after the treatment of NTP technology. Before and after the treatment of NTP technology, the mass fractions of the SOF were 31.12% and 24.36%, and the total weight-loss ratios of the PM samples were 95.63% and 94.89% from 25℃ to 1000℃. Simultaneously, the temperature of the exothermic peak of PM samples was decreased 67.5℃ after the treatment of NTP technology.
