| 摘 要： | 采用AVL全流采样(CVS)系统,对2台国Ⅴ车用重型柴油机进行了ESC和ETC循环试验,并利用气相色谱—质谱联用仪等设备对颗粒物中的可溶性有机物(SOF)和多环芳烃(PAHs)进行了分析。通过对比采用DOC+DPF和SCR两种技术路线柴油机的SOF和PAHs及其组分,对它们的排放特性进行了研究。研究发现,无论是ESC循环下还是ETC循环下,DOC+DPF路线发动机PM排放中SOF含量以及PAHs排放总浓度都要明显低于SCR路线发动机,PM中菲和芘的浓度会降低一半以上。

| Abstract: | The ESC and ETC experiments of two stage Ⅴ heavy-duty diesel engines were carried out with AVL constant volume sample system(CVS),and the soluble organic fraction(SOF) and polycyclic aromatic hydrocarbons(PAHs) were analyzed with the GC-MS equipment.The emission characteristics of SOF and PAHs were studied by comparing their respective content of DOC+DPF and SCR routes.It was found that the SOF content in PM and the PAHs total concentration of DOC+DPF route were obviously lower than those of SCR route whether during the ESC or the ETC.In addition,the phenanthrene and pyrene in PM would reduce by more than 50%. |
