【Abstract】 In this paper,the calculation model of the combustion chemistry and thermodynamieal parameters of actuating medium,which is not only for diesel oil but al- so for emulsified oil—methanol—water ternary fule,was presented.And the calculation results of heat release rate in D.I.diesel engine were given.Then the influences of fac- tors,such as tunnel effect of pressure sensor,latent heat of water,calculation step and P —V diagram smoothing effect,on the calculating accuracy of heat release rate were anal- ysed.更多还原
