Experimental Investigation on Performance and Emission Parameters of Single Cylinder Diesel Engine Using Castor Seed Methyl Ester Blends

In the present investigation castor-diesel blend is used as an alternate fuel. The properties of castor seed oil are determined and castor seed oil is converted in castor seed methyl esters by esterification process. The performance and emissions parameters of single cylinder, stationary diesel engine were calculated with the blends (B10, B20, B30) prepared and with the standard diesel and graphs were plotted. The obtained results were compared with the base line data obtained by using diesel and optimum castor seed oil blend B10 is obtained. The blend showed best performance in brake thermal efficiency, increase in brake thermal efficiency, and decrease in brake specific consumption and reduction in CO, HC emissions. Finally results shows that castor seed methyl esters can be used as alternate fuel for Diesel engines. Keywords— Castor Seed oil, Esterification, Performance and Emission Parameters.
