Performance Analysis of a Diesel Engine using the Soybean Oil based Biodiesel


This paper gives an overview of the investigation being done for the preparation of biodiesel from soybean oil using the Transesterfication technique with the help of KOH, used as a catalyst. Prepared biodiesel can be used as an alternative to the diesel that is currently being used in automobiles. Diesel being a non-renewable product is under a great risk of depletion and with the depletion of this product, life on earth would be severely affected. Thus, an alternative source of power is required to be developed. Biodiesel being a renewable source of energy comes out to be the best alternative of diesel. Biodiesel produced by using different blends of soyabean oil is being used and tested in a VCR type 4-stroke diesel engine. It has been observed that feeding vegetable oil directly to the engine for a longer period may cause working problems and disturbances to the engine. These problems are due to physical properties of oil like viscosity, volatility and polyunsaturated character. Transesterfication process comes out as an effective solution of this problem as it reduces fluid viscosity and other operational errors from the oil. Methyl ester of soybean oil (SBD) were found to be very similar to mineral diesel due to this, a mixture of SBD and mineral diesel were used to make different blends of biodiesel which were then fed to a CI engine as fuels. Engine was tested for different blend of biodiesel at 1500 rpm at different loading conditions and its performance parameters were analysed. The outcome of the investigation has proved that biodiesel exhibits physical properties which are similar to that of mineral diesel. It is to be noted that the BSFC (Brake Specific Fuel Consumption) of biodiesel is more as it has low heating point. Use of Biodiesel in automobiles has shown a notable amount of reduction in CO, HC, NOx . So Biodiesel can be an alternative of mineral diesel.
