Sustainability Analysis of Castor Blend (B10 & B15) Fuel by Examine the Change in Engine Lubrication Properties

In present study, an analysis has been performed on the effect of plain diesel and castor/diesel bio-fuel on the lubricity of engine oil. Initially castor blend (B15) bio-fuel is prepared by esterification process in which NaOH (1.75g) and methanol (50 ml) are used as a catalyst. Thermo physical properties of blend are measured and the samples are used in 4-stroke diesel engine test rig under 2000 W 6000 W load. Viscosity, density flash point and fire point of used engine oil from plain diesel and blend are examined. Viscosity of used engine oil is observed higher in the case of castor blend (1480.4mm2/s) as compared to plain diesel. FTIR spectra shows the presence of alternative fuel lubrication have advantage as compared to plain diesel. FTIR results show that more oxidation and Sulphation (1000-1600 cm-1) in the case of plain diesel as compared to blend fuel B10 & B15.Further, initial wave no. (725.26 cm-1) of FTIR indicates, higher dilution of fuel with plain diesel as compared with B10 & B15.
