This paper investigates the performance, emissions, and combustion characteristics of a dual fuel diesel engine fueled by CNG (Compressed Natural Gas) as the main fuel. The experiments used two fuels for the ignition: one is OME (Oleate Methyl Ester), a major component of biodiesel, and the other is ordinary gas oil. The results show that the conditions where operation with CNG/OME is possible are very similar to those of CNG/gas oil. When the CNG supply rate was raised to 75%, the brake thermal efficiency was similar to that of ordinary diesel operation at BMEP=0.65MPa. When the CNG supply rate was higher than 75% ignition became very unstable and the brake thermal efficiency decreased significantly as well as the HC and NOx emissions increased sharply.
