Furthermore, the effects of blended fuels on engine performance were investigated and results showed that methanol gasoline blends presents the highest volumetric efficiency and torque; ethanol gasoline blends provides the highest brake power, while ethanol methanol gasoline blends showed a moderate level of volumetric efficiency, torque and brake power between both methanol gasoline and ethanol gasoline blends; gasoline, on the other hand, showed the lowest volumetric efficiency, torque and brake power among all test fuels.
