In recent decades, motorcycles relied on carburetors for fuel mixing, but their limitations become evident with stricter emission regulations and varied operating conditions. Electronic fuel injection (EFI) emerged as superior solution, offering benefits such as enhanced performance and fuel efficiency. This study focused on modifying Honda XR 125 motorcycle by installing Yamaha genuine parts compatible with a programmable ECU. Optimized modes were identified for different ethanol blends. This study conducted tests on MT511 Motorcycle Dynamometer using various modes and hydrous fuel blends. The E10 exhibits fuel consumption rates of 37.77 km/L using Mode 1. It was increased by 5% compared to previous carbureted consumption rates which is 35.35 km/L. Mode 1, optimized for E10 to E40 blends, achieved maximum torque of 35.11 N-m, 4.3 kW of power, and air-fuel ratio from 12.10 to 15.00. Mode 2, for blends of E50 to E70, attained maximum torque of 14.75 N-m, 2 kW of power, and air-fuel ratio from 12.70 to 16.70. Mode 3, optimized for E80, reached maximum torque of 9.69 N-m, 2.1 Kw of power, and air-fuel ratio from 13.50 to 17.80. Mode 4, optimized for E90 and E100, achieved maximum torque of 10.50 N m, 2.34 kW of power, and air-fuel ratio from 13.00 to 17.50. These results indicates that different ethanol blends was optimized, enhancing power, torque, and speed. The findings could be valuable for future researchers interested in alternative fuel injection systems. Long-term testing is recommended to further observe the effects of hydrous bioethanol on fuel injection system components. |
