An Experimental Investigation of DI Diesel Engine Fuelled with Emulsions of Mahua Bio-Oil

This paper describes the performance and emission parameters of a DI diesel engine fuelled with Mahua Bio-Oil (MBO) diesel emulsion with Diethyl Ether (DEE) as an ignition improver and tween 20 as surfactant. An attempt was made to use emulsified bio-oil with diesel fuel in a single cylinder, four stroke, water cooled, DI diesel engine. The performance and exhaust emissions were measured from the diesel engine at different power outputs. The performance and exhaust emissions were studied from the engine with diesel and four different MBO emulsions. BTE of the engine operated with MBO emulsions was found to be higher than that of diesel. EGT is found to be more when compared to diesel and was increasing with increased emulsions. The smoke and NO emissions are found to be reduced in the case of emulsions when compared with that of diesel.
