Experimental Study of the Effect of Castor Oil Biodiesel Fuel on Performance and Emissions of Turbocharged DI Diesel

Experimental tests were carried out on a semi-heavy duty Motorsazan MT4.244 agricultural engine at various loads in order to evaluate performance and emissions of DI diesel engine using the blends ofdiesel fuel with 5, 10,15,20, 30%(by volume) Castor oil and pure diesel fuel separately. The resultsshow that maximum decrease in PM emission compared to that of pure diesel fuel is 73.2% and observed in B15 at 50% load. Also, the maximum increase in BSFC and No when compared to those of pure diesel fuel are 10.7 and 15.6% and observed in B30 at 50% load and B20 at 50% load,respectively. The results show that in B15 and at 25% load, NO and PM emissions decreases 6 and 64% respectively and BSFC increases 1.5%.
