Abstract—Biodiesel has been a promising clean alternative fuel to fossil fuels, which cuts the emissions that are released by fossil fuels, and perhaps reduces the energy crisis induced by the exhaustion of oil resources in the near future. In this study, the effect of antioxidant additive on engine performance and emission characteristics of an engine fueled with palm biodiesel was investigated and compared with conventional diesel fuel. For this study, four fuel samples including pure diesel, diesel-biodiesel (B20), diesel-biodiesel-additive (B20+additive) and pure biodiesel (B100) were used in a multi cylinder, four stroke, water cooled, direct injection diesel engine. Engine tests were performed at various engine speed of 1000 rpm to 4000 rpm with 50% throttle opening. Engine performance and emission concentrations are investigated by determining the break specific fuel consumption (BSFC), brake thermal efficiency, CO, HC, NOx and smoke opacity using gas analyzers. The results showed that the use of baynox plus solution as additive with palm methylester gave average 3.10% higher brake power as well as 23.2% and 2.40% lower NOx and brake specific fuel consumption than the biodiesel blend without additives.
