Vegetable oils are considered possible replacement fuels for diesel engines; however, past research has shown that long term engine durability is adversely affected by the use of these fuels. Most researchers have attempted to reduce the problems associated with vegetable oil fuels either by the formation of vegetable oil/diesel blends or the esterfication of the vegetable oils. In this investigation of an alternative approach, the performance of saponified soybean oil/aqueous ethanol microcellular solutions were tested in a single-cylinder, direct injection, air-cooled diesel engine. The products of the pyrolytic distillation of crude soybean oil were mixed with 150 proof ethanol in the ratio of 4:1 by volume and saponified with anhydrous ammonia gas. This ''parent fuel'' was then diluted with 150 proof ethanol to obtain two test fuels, one with 30 percent ethanol concentration and the other with 40 percent ethanol concentration. The fuels were used in the engine under various loads at two speeds, and the performance was compared to the performance using No. 2-D commercial diesel fuel.
