Abstract

Increased use of gasoline engines results in scarcity of fuel and air pollution. Butanol is a renewable alternative fuel that can improve engine performance and reduce exhaust emissions. Therefore, the current study focuses on the use of butanol as an alternative fuel for gasoline engines by investigating the impact of its use on engine performance and exhaust emissions with the exhaust gas recirculation (EGR) system. Butanol in this study varied in the range of 5% to 15% in conditions without EGR, hot EGR, and cold EGR. From these experimental results, it was found that torque and power increased by 15.8% in the addition of 15% butanol with cold EGR. The use of hot EGR with the addition of 15% butanol in fuel can reduce BSFC 18.9% and increase BTE 23.2% from without EGR system. EGT decreased by 5.7% by using cold EGR. The addition of 15% butanol in fuel reduces CO emissions by 74.2% and HC emissions by 46.3% from pure gasoline. Butanol 15% in fuel increases CO2 emissions by 19.04% and 10% butanol decreases O2 to 34.6% in cold EGR systems.
