| 摘 要： | 使用电子低压撞击仪(ELPI)分级粒径采集了柴油机的排气微粒,应用热重分析(TGA)方法研究了发动机燃用柴油和两种生物柴油时,排气微粒中挥发性物质(VOF)的含量。研究结果表明:燃用生物柴油,排气微粒VOF含量高于纯柴油,排气中小粒径微粒的VOF质量百分比均高于柴油,与总微粒的排放规律相同;超细微粒(d<0.100μm)具有较高的VOF质量百分比。柴油机燃用生物柴油后,总微粒中VOF质量百分比从44.917%上升到70.767%,在0.100μm

| Abstract: | The particulate matter(PM) of a diesel engine was sampled by using electrical low pressure impactor(ELPI),volatile fraction(VOF) in PM of the diesel engine was analyzed by the thermo-gravimetric analysis(TGA) when the engine was fueled with diesel fuel and biodiesel.The results show that the VOF content in PM when the engine is fueled with biodiesel is higher than that when the engine is fueled with diesel fuel.VOF content in PM with smaller size when the engine is fueled with biodiesel is higher than that ... |
