A feasibility study was made on the use of the soy bean oil as an alternative fuel for diesel engines. The application to diesel engines was tried using the methyl ester fuel and the blended fuel which mixed the soy bean oil with the kerosene. The methyl ester fuel was made by esterification of the soy bean oil with the methyl alcohol. The mixing ratios of the blended fuels were varied from 20 to 80% in volume. The lower calorific value, density, surface tension and kinematic viscosity of the test fuels were measured. In addition, the ignition test was carried out and found to be improved the ignitionability by esterification and mixing kerosen. Finally the test fuels were burned in a conventional 273-cc diesel engine. Although the thermal efficiency was almost the same, the smoke scale in the exhaust gas was confirmed to be reduced compared with the gas oil.
