A Study Of Fuel Properties Of Ternary Blend Diesel-Mahuva Methyl Ester-Ethanol
A number of studies currently focus on the renewable fuels to reduce the reliance on petroleum fuels. Bio fuels
such as ethanol and biodiesel have been studied and tested in many countries including India. One of the methods to reduce
the use of fossil fuel is blending ethanol and biodiesel with fossil diesel. Adding ethanol to the diesel fuel alters the
properties of the diesel fuel which does not meet some of the standards. However addition of biodiesel to this blend helps in
regaining the fuel properties to the standard values and thus the blend can be efficiently used in the existing diesel engines.
Mahuva methyl ester (MME) offers an alternative application as an emulsifier for diesel and ethanol blends. The present
work is aimed to investigate experimentally the physic-chemical properties of the ternary fuel blend (diesel-biodieselethanol).
Blend was prepared by varying the MME proportion as 20%, 30% and 40% by keeping the ethanol proportion as
10% constant. The tested fuel properties were compared with that of diesel fuel. The tested fuel properties are density,
viscosity, heat of combustion, flash point, pour point, cloud point, water and sediment, sulphur, ash, oxygen content of
ternary blend, and cetane number was calculated by empirical formula. It was found that the fuel properties of ternary fuel
blends were close to the standard values of diesel fuel. The functional group of the blend was analyzed by FTIR method and
fatty acid composition of the blend was determined by GC method. Absorption spectrum of the blended fuel was analyzed
by UV method.
