A proposed modification or an innovation can be analyzed quickly using a computer simulation and cost overrun in setting up an experimental work can be minimized by the optimization of experimental parameters beforehand. Literature data for performance prediction of direct injection diesel engine operated either with diesel fuels having property variation or with oxygenated diesel blends were found mostly confined to experimental investigations only. In modern research, computer simulation has become a powerful tool for diesel engine performance prediction as it saves time and is also economical in the analysis of modifications. In a finely tuned and warm engine, the thermodynamic models are capable of reproducing cylinder pressure and over all engine performance with acceptable accuracy over a wide range of operating conditions.
