Abstract

The increasing number of gasoline engines as a mode of transportation has an impact on increasing the consumption of gasoline fuel, which is becoming increasingly depleted and rising air pollution, especially in urban areas. To overcome this problem, ethanol as an alternative fuel was blended with gasoline in this study. Therefore, this study is intended to investigate the performance and exhaust emissions of gasoline engine fueled by gasoline and wet ethanol applying the exhaust gas recirculation (EGR) system. Wet ethanol was used as an alternative fuel because the price is competitive with gasoline. The percentage of wet ethanol blended into gasoline was in the range of 5% to 15%. This experiment was carried out at engine speed variations of 2500 rpm to 4000 rpm at intervals of 500 rpm. The results of this experiment illustrate that blending 15% wet ethanol into gasoline without EGR produces an increase of 11.74% torque, 11.73% brake power, and brake specific fuel consumption (BSFC) of 3.80%, exhaust gas temperature of 4.1%, and 38.7% thermal efficiency than that of P100. Addition of 10% wet ethanol into gasoline fuel reduces 41.1% CO and 44.30% HC emissions. Meanwhile, the use of cold EGR with the addition of 10% wet ethanol increases CO2 emissions by 28.1% and decreases O2 by 7.5%.
