Technical Abstract: A vegetable oil was first used in a diesel engine in 1900. In the following decades up to approximately 1950, numerous reports discuss the fuel use of vegetable oils. The background at that time, including some reports in the United States, was often energy security. The aspect of energy security is now playing a significant role again in promoting the cause of alternative fuels such as biodiesel, the currently most common form of vegetable oil-derived diesel fuel. Other driving forces include environmental benefits in form of reduced exhaust emissions and the utilization of surplus agriculturally-derived materials such as soybean oil. Several significant research problems facing biodiesel are reduction of nitrogen oxides exhaust emissions, improvement of cold-flow properties, storage stability and improved analytical methods.
