%X In this work, computer simulation framework for compression ignition engine cycle simulation is developed and engine performance is predicted. Double wiebe¡¯s function is used to model the rate of heat release due to combustion to predict heat released during premixed as well as diffusive phase of combustion. Effect of convective heat transfer and variation in specific heat of test fuels are also considered during development of model. Suitable correlations are established between adjustable parameters of wiebe¡¯s function, relative air-fuel ratio and engine operating conditions, such that the simulated heat release profile matches closely with experimental results. The simulation model is used to analyze the performance, combustion and emission characteristics of single cylinder 3.5 kW rated power diesel engine fuelled with Diesel (D0), Palm Oil Methyl Ester (POME) and POME-diesel blends. The model validation is done by comparing the predicted parameters like brake thermal efficiency and in-cylinder pressure with experimental results and are found in closer approximation. The model is also used to predict net heat release rate, exhaust gas temperature, NOx and soot.
