Vegetable oils appear to be one of the alternative fuels for supplementing diesel fuel in the future. Considering the CO_2 problem, alternative fuels from regenerated vegetable energy sources have many advantages. Furthermore, vegetable oils are suitable for use in agricultural machine engines with respect to the user's capability of self-support. In studies of vegetable oils, the mixtures of gas oil or ethanol with vegetable oils and vegetable oil methyl esters on engine performance and exhaust emissions have been reported. This paper describes experiments with stable water-emulsified rapeseed oils in a small direct-injection diesel engine for utilization as a diesel fuel. The results show that the NO_x concentration decreases remarkably with increasing water content. However, an optimum water content exists with respect to engine performance and exhaust smoke concentration.
