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

در كار ارايه شده، آزمون هاي تجربي بر روي يك موتور كشاورزي نيمه سنگين (MT4.244) كارخانه موتورسازاندر بارهاي مختلف به منظور ارزيابي عملكرد و آلايندگي در حالت سوخت مخلوط ديزل و بيوديزل (Castor oil) با نسبت هاي حجمي 5%, 10,15,20 , 30 انجام شده است. نتايج نشان مي دهند كه بيشترين كاهش دوده در حالت دو سوخته 73.2% در بار 50% و در سوخت B15مشاهده مي شود. همچنين، بيشترين افزايش درBSFC و NO به ترتيب10.7 و 15.6% در سوخت B30 و B20 در بار50% مشاهده مي شوند. نتايج نشان مي دهند كه در B15 و در بار 50% ،NO و PMبه ترتيب 6 و 64% كاهش و BSFC1.5% افزايش مي يابد.

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 of diesel fuel with 5, 10,15,20, 30%(by volume) Castor oil and pure diesel fuel separately. The results show 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%.
