Abstract
A computer model is being developed at DREO to simulate the combustion process in diesel engines, and in particular to acquire the ability to predict the effects of future lower grade fuels on diesel engine performance. A baseline thermodynamic model has been completed. Two rate equations developed by Whitehouse and Way, describe the transient fuel/air mixing and reaction kinetic processes. A parametric study was initiated to obtain a better understanding of the sensitivity of fuel parameters and modelling constants on the model's output. It was found that the model produces pressure and heat release diagrams with the correct shape and magnitude. The model predicted the correct trending in all cases studied. In order to use the model as a predictive tool, the effect of engine and fuel variables on the modelling constants will have to be determined.
