Prediction of Low Temperature Viscous Behaviour of Bio-diesel from Karanja Oil Methyl Ester

摘要

The utilization of bio-diesel as a fuel significantly depends on its viscosity.In the present investigation,the viscous behaviour of Karanja oil ester was investigated for use as a potential and alternating fuel.Blends of the ester and oil were prepared,analyzed and compared with diesel fuel.The effect of temperature on viscosity of bio-diesel and Karanja oil was determined.The different samples were examined in the range of 0-20°C.Empirical relations for the temperature dependence of viscosity were computed.Above 0°C,these relations described all measurements well.Below 0°C,the viscosity was observed to decrease due to the crystallization of the ester.
