Abstract:
As there is a significant increase in vehicle population and subsequent decrease in natural fuel resources ,the world is in the need to look for alternative fuels which can be substituted for the usage of the conventional fuels. so biofuels are now in the focus of researchers which have been seen as a reliable alternative for the conventional fuels. In this investigation, The biodiesel from the coconut (cocus nucifera) oil has been prepared by using the process of enzymatic transesterification process. Coconut oil is colorless or yellowish which is having a good taste and smell. It is used to produce biodiesel by using enzymatic transesterification process and the produced bio diesel is blended with diesel by various proportions The proportions are B0(100% Diesel),B10(10% Biodiesel &90 % Diesel),B20(20%Biodiesel&80%Diesel).Subsequently the fuel properties and performance parameters like flash point fire point, viscosity, density, calorific value brake specific fuel consumption, brake power, indicated power brake thermal efficiency and mechanical efficiency have been determined by fuelling the above blends in the kirlosker computerized IC engine. The emission characteristics like CO,CO2, NOX and HC contents have also been measured using gas analyzer .the obtained results are then compared with the diesel(B0).According to the results the suitable blend may be selected and can be used for commercial purpose.
