    Abstract:

    The combustion characteristics and the variation of incylinder reaction species were investigated for DIdiesel engines with various fuels (diesel,toluene,cetane,dodecane,nheptane and iheptane) using computational fluid dynamics (CFD) technique.Meanwhile,an analysis was made of the correlation between the rate of heat release and reaction species.The results show that,the model is reasonable and the calculated values of incylinder pressure keep in accordance with experimental ones in references.Compared to other fuels,for toluene,four species (H,N,OH and O) generated in combustion process,incylinder pressure,rate of heat release and accumulated heat release are the highest.In addition,as to various fuels,the amount of OH species generated is also the highest.
