ABSTRACT
In this work, ethanol was blended with palm methyl ester (PME) and conventional diesel fuel. The effect of ethanol concentration and PME on diesel and both the performance and emissions were investigated. Both low and high concentrations of ethanol and biodiesel were studied. The results showed that ethanol, biodiesel, and diesel blends lead to a positive effect on the reduction in the nitrogen oxide. Brake thermal efficiency (BThE) was better in different blends (methyl ester of palm oil, ethanol, and diesel) as compared to pure diesel. Moreover, a comparative trade-off analysis was done among BThE, brake specific fuel consumption, and NOx to reflect the performance and emission characteristics at a time.
