Biodiesel is alternative diesel fuel, and a mixture of fatty acid methyl esters with other impurities. The combustion characteristics of biodiesel may be influenced by the compositions of fatty acid methyl esters in the biodiesel. In order to understand the effects of the fatty acid methyl ester compositions on biodiesel combustion, the diesel combustion of the blended fuels of the oleic and palmitic acid methyl esters are investigated using a small DI diesel engine. As the results, ignition delay and NO_x emissions decrease with higher fraction of palmitic acid methyl ester in the blended fuels. It is considered that the ignitionability of palmitic acid methyl ester is better than that of oleic acid methyl ester because of the lower boiling point of palmitic acid methyl ester.
