 note = {Isopentanol and isobutanol were selected as the next generation bio-alcohols in the study, and four kinds of bio-alcohol blended fuels were prepared by blending at a constant mass ratio of 3:7 into the two kinds of FAME fuels. The base fuels used here were methyl laurate (LME) and a blend with equal proportions of methyl palmitate (PME) and LME, termed PLME. The bio-alcohol blended FAME fuels were supplied to a small single cylinder direct injection diesel engine, and the effects on engine performance, combustion characteristics, and exhaust emissions were investigated. The boost pressures were set at two conditions: 100 kPa (without supercharging) and 120 kPa (with supercharging), and the EGR rates were varied from 0 to 28.5%. The results showed that regardless of EGR rate, and with and without supercharging, the trade-off relation between NOx and smoke emissions with all the bio-alcohol blended FAME fuels improved significantly while maintaining good brake thermal efficiency compared with conventional diesel fuel operation. Further, as a result of the ignition delay measurements employing standard fuels, it was found that the estimated cetane numbers of the tested bio-alcohol blended FAME fuels are strongly dependent on the estimated cetane number of the base fuel.},
