| 摘 要： | 在高压共轨柴油机上对生物柴油混合燃料(源自食用废油)的排放物进行了研究.结果表明,限制性气体排放中,随着生物柴油混合比例的增加,Nox的排放量明显升高,同时在氧化催化器后Nox中的NO2体积分数也逐步增大;烟度则随着燃料混合比例的增加呈线性下降.非限制性气体排放中,外特性工况下的生物柴油混合燃料的乙醛排放量随混合比的增加而降低;SO2气体排放量也随着燃料混合比例的增加逐步下降,纯生物柴油可降低20%～60%.生物柴油的颗粒粒径分布表明,生物柴油的核态纳米颗粒对混合燃料的硫含量非常敏感,由于纯生物柴油硫含量低,故可以有效降低颗粒的总数量浓度.

| Abstract: | Characteristics of regulated and unregulated emissions of biodiesel blends(derived from waste oil)in a common rail diesel engine without any modification were investigated.The results showed that NOx emissions increase significantly with a higher blend ratio and NO2 concentration increases after two diesel oxidation catalysts.A linear relationship between the reduction of smoke number and the blend concentration is found.For unregulated gas emissions,MECHO emission is reduced with a higher blend concentrati... |
