SIMULATION OF COMBUSTION PROCESS OF A DIESEL ENGINE FUELLED WITH BIOFUELS

A thermodinamic model has been used to investigate the combustion performance of a four cylinder direct injection diesel engine fueled by biofuels The numerical simulation was performed at constant speed. The indicated pressure, temperature diagrams are plotted and compared for different fuels. The emissions of soot and nitrous oxide are computed with phenomenological models. The experimental work was also carried out with biodiesel diesel blends, to validate simulation results with experimental results, and observed that the present model is successful in predicting the engine performance with biofuels.
