Evaluation of carbonyl emission from diesel engine generator using biodiesel fuel

Abstract

This research was carried out to measure and evaluate the emission of particulate matters and the emission of carbonyl compounds from diesel engine KAMA - KDE3500T generator under 1.5 kW load for seven test fuels: B0 (pure diesel fuel) B10 (10 % palm biodiesel + 90 % pure diesel fuel), B20, B30, B50, B75, and B100, respectively. The results showed that the emission concentration of particulate matters reduced from B0 to B20, and increased from B30 to B100. The concrete data were that 348.65 mg/m3, 297.27 mg/m3, 168.59 mg/m3, 169.74 mg/m3, 259.98 mg/m3, 330.30 mg/m3 and 522.98 mg/m3 for B0, B10, B20, B30, B50, B75 and B100, respectively. The emission concentration of carbonyl compound raised form B0 to B30, and suddenly decreased at B50, and increased again from B75 to B100. The concrete data were that 67.99 mg/m3, 87.35 mg/m3, 99.10 mg/m3, 100.96 mg/m3, 65.79 mg/m3, 102.32 mg/m3, 102.38 mg/m3 for B0, B10, B20, B30, B50, B75 and B100, respectively. The highest concentration compounds were formaldehyde, acetaldehyde, and acetone.
