Resumo

Compliance with the limited oil reserves on the earth and governmental regulations about the environment to meet emission standards leads to the quest for fuels which are eco-friendly and safe for the human beings. It is now well established that lower blends of biodiesel and diesel works well in the existing engines without any modifications due to the similarity of the bio fuels to the diesel fuel. Experimental investigation was carried out in a single cylinder direct injection diesel engine fuelled with diesel, soybean oil methyl ester (SOME) and 20SOME (80% diesel+20% Soybean oil methyl ester). The performance such as brake thermal efficiency and exhaust gas temperature (EGT) at different brake power and exhaust emission characteristics such as unburned hydrocarbon (UBHC), Carbon monoxide (CO), oxides of Nitrogen (NOx), and smoke density at different brake power and compared with diesel fuel. The investigation revealed that the engine performance under biodiesel blend 20SOME was similar to that of pure diesel fuel with nearly the same brake thermal efficiency and the maximum emission of smoke for 20SOME blend was same as for diesel. The carbon monoxide and hydrocarbon emissions decreased significantly compared to neat diesel fuel. Keywords: Emission, soybean oil, biodiesel, CO
