In this paper an effort has been made to simulate the combustion and performance of a turbocharged diesel engine fuelled with oxygenate blended diesel. In this simulation a comprehensive analysis of combustion, heat release, heat transfer and performance of a turbocharged diesel engine was carried out with Diethylene glycol dimethyl ether (Diglyme) blended diesel.The CI engine cycle was simulated for both neat diesel and oxygenate blended diesel fuel operations with a closer duration of each degree crank angle. Heat release was calculated using WIEBE's heat release model under the consideration of two-zone combustion. The thermodynamic property at each degree crank angle was calculated based on the first law of thermodynamics. The fluid motion is considered with swirl inside the engine cylinder. The gas-wall heat transfer calculations are based on ANNAND's heat transfer model for IC engines. In the gas exchange model, gas flow rates through the intake and exhaust system were calculated.To validate the predicted results, experimental investigation was carried out under identical conditions on a turbocharged diesel engine. Diethylene glycol dimethyl ether (Diglyme) is used as oxygenate by blending 5% (by volume) with diesel. Addition of oxygenate had resulted in considerable decrease in the fuel consumption and improvement in the combustion and thermal efficiency for the power output equivalence of diesel fuel. The combustion and performance parameters were studied and its trends were found to be satisfactory and well within the limits.The synthesized performance values such as brake power output, brake thermal efficiency and brake specific fuel consumption at various engine speeds have been found in agreement with the experimental values.
