摘要
In this paper,the influence of aromatic content,one of main fuel properties,on diesel particulate emissions was studied at five steady-state operating conditions using a heavy-duty Perkins 4.236 engine.Detailed analysis of the particulate showed the presence of biologically active polynuclear aromatic hydrocarbons(PAH) in high concentration.Unburnt PAH in liquid fuel are identified to be the dominant source of particulate PAH.Diesel particulates are also considered a potential health hazard because of the presence of PAH in the SOF of the particulates and some of these PAH are known to be carcinogenic.
