A society system of mass production, mass consumption and mass wastes causes serious environmental problem. Especially, the poison such as the soot exhausted by the diesel engine is a problem. Recently, because the chemical composition of light oil as the diesel engine fuel is assumed the problem, the biography diesel fuel is paid to attention as a light oil alternative fuel. The biography diesel fuel is made from the methanol, the potassium hydroxide, and the abolition vegetable oil. In this Research, we have aimed at systematization of biography diesel fuel production by supersonic wave, evaluation the system, and development for practical production.
