Abstract

This research aims to improve the combustion perfor- mance of gasoline-bioethanol fuel blended in the ratio of 50:50 (E50) on the spark-ignition engine by employ- ing a new combustion strategy. The Box Behnken Design of Response Surface Methodology and Non- Linear Programming was employed to optimize the performance of the engine and create some engine parameters. The performance of the engine consists of power, torque, thermal efficiency, fuel consumption, and the emission of CO and HC, while the engine and combustion parameters are compression ratio, ignition timing, and engine speed. A new combustion strategy will be applied in this study with a tiered mapping process for each engine parameter based on the MBT. The brake torque increased by 13.5 % while HC and CO emissions decreased by 15 % and 71 % respectively when the combustion strategy applied if compared o the pure gasoline in engine standard condition. Furthermore, the BSFC increased by 33 % while BTE decreased by 15 % towards the gasoline fuel. The non- linear programming applied in this study intended to figure out the best combination of the engine param- eters in obtaining optimum engine performances. In the RSM analysis, the codes –1, 0, 1 represented 12, 12.5, and 13 of compression ratio, 16, 20, and 24 BTDC of ignition timing and 2000, 5000, and 8000 rpm of engine speed. Therefore, 20 BTDC of ignition timing and 13:1 of compression ratio is the optimum engine
