This study investigates the effect of pyrogallol (PY) and butylated hydroxyanisole (BHA) on the brake thermal efficiency (BTE) of palm biodiesel blends. A single cylinder CI engine was used to test palm biodiesel with PY and BHA additives at 800 ppm concentrations under various load conditions. Engine performance measures, including brake power (BP) and brake thermal efficiency (BTE), were evaluated. Results found that at 1800 rpm, the B20+PY and B20+BHA blended fuels show increases of 12.5% and 6.9% in brake power, along with improvements of 12% and 8% in torque compared to the same blends without additives, respectively. The BTE was determined to be 16.1% and 8.7% higher for the B20+PY and B20+BHA fuel blends, respectively. The PY additives enhanced engine performance by approximately double in comparison to BHA. In conclusion, the performance of the palm biodiesel blends with additives surpasses that of blends without additives, with PY showing better efficiency compared to BHA.
