Investigation of Effect of Chicken Biodiesel Blended Diesel on Engine Performance

Abstract

Now a day’s fossil fuels usage has become more, hence the fossil fuels are getting depleted day by day. So in order to overcome this problem we have to go for alternative fuels. Rendered animal fats and restaurant waste oils are appealing feedstock to
produce biodiesel. The price of virgin vegetable oil is about two times more than that of animal fat, but drawbacks of using animal
fat as a raw material for biodiesel production is its physical properties which could be eliminated by adding necessary amount of
alcohol, catalyst for a required period of time. Extracted fat is heated to produce chicken biodiesel. Trans esterification of chicken
fat is done. KOH is used as catalyst and methanol will increase the reaction. The blending process was carried out with appropriate volume of diesel and chicken biodiesel and kept for 24 hours to observe the formation of layer. The fuel properties
like flash point, fire point, calorific value, viscosity are found. Test is carried out on single cylinder four stroke engines with
different composition like 5%, 10%, 15% and 20% of chicken biodiesel blend with diesel. The fuel properties like flash point, fire
point, calorific value, viscosity are found for chicken biodiesel and for different blend compositions. Variation of brake power,
calorific value, kinematic viscosity and density for different blends and specific fuel consumption and brake thermal efficiency for
constant loads are shown with the help of graphs. The biodiesel with 20% blend gives higher value of brake power and brake
thermal efficiency compare to diesel and other blends. Result shows chicken biodiesel is an effective biofuel for future.
