This paper investigates the performance, combustion characteristics, and emissions of a small single cylinder DI diesel engine with biodiesel fuels derived from unused rape oil, soybean oil, and palm oil. Compared with ordinary gas oil, all the BDF showed slightly higher brake thermal efficiencies and considerably reduced smoke densities while the NO_x emissions were somewhat higher. The BDF also showed better ignitability than with gas oil operation, especially that with palm oil BDF. The rape oil BDF and palm oil BDF used in the tests are mainly composed of Oleate Methyl Ester (OME) and Palmitate Methyl Ester (PME). Therefore, the engine performance, combustion characteristics, and emissions were examined using neat OME and OME-PME blends. As a result, the neat OME and OME-PME blends showed good ignitability and combustion stability like that of gas oil operation.
