2014中国汽车工程学会年会用户论文集：Wide Distillation FuelI(WDF) refers to the fuels with a distillation range from initial boiling point(IBP) of gasoline to final boiling point(FBP) of diesel.Effects of gasoline research octane number(RON) and diesel cetane number(CN) on WDF low temperature combustion(LTC) were investigated on a injection diesel engine under moderate exhaust gas recirulation(EGR) and injection pressure with two series of WDFs,one has different gasoline RONs and the other has different diesel CNs.The results indicated that gasoline RON shows little effects on WDFs with blending ratio of 50:50;diesel CN has more profound effects on WDF LTC combustion than gasoline RON.High diesel CN can reduce ignition delay and improve heat release.WDFs with higher CN diesel have lower CO,THC emissions and higher thermal efficiency,while soot and NOx emissions are similar regardless of the diesel CN.汽油的辛烷值、柴油十六烷值对蒸馏燃料低温燃烧的影响
