正丁醇/柴油RCCI发动机排放碳烟颗粒的化学特性
Chemical Characteristics of Soot Particles Emitted by N-butanol/Diesel RCCI Engines
摘要
Abstract
With the help of Fourier transform infrared spectrometer(FTIR)and X-ray photoelectron spectroscopy(XPS),based on a modified six-cylinder heavy-duty diesel engine,this paper studied the differ-ent start of injection(SOI)and the premix ratio(Rp)under the n-butanol/diesel reactivity controlled com-pression ignition(RCCI)soot particle of chemical characteristic,and compared with the conventional diesel combustion(CDC)model contrast research,The main conclusions are as follows:the advance of SOI and the increase of Rp lead to an increasing trend in the relative contents of aliphatic C-H functional groups and oxygen-containing functional groups.Under the same SOI,the relative contents of aliphatic C-H functional groups and oxygen-containing functional groups in RCCI mode are higher than those in CDC mode.It is worth noting that the content of C-OH functional groups is higher than that of C=O function-al groups in CDC mode,while the opposite result occurs in RCCI mode.O/C increases slightly with the in-crease of Rp.The O/C of RCCI mode is higher than that of CDC mode,and the changes of SOI have no ob-vious impact pattern on O/C.For the hybrid form of carbon atoms,the change of SOI and Rp has little ef-fect on sp3/sp2,while the change of combustion mode has great effect on sp3/sp2.关键词
