Abstract
Paper presents research results of selected physicochemical properties of water-fuel microemulsion, that can be used as a fuel for a diesel engines. Tests were carried out for a diesel oil blended with selected surfactants and water at 4 and 8 % by mass. Tested microemulsions contained a surfactant and cosurfactanst, ie., PEG-40 and PEG-7. The addition of these chemicals and water to the diesel oil allows to formulate a fuel microemulsions marked by a code C4 and C8. Both tested microemulsions are thermodynamically stable and transparent. Their density is slightly greater (approx. 1%) compared to diesel oil. It was observed an impact of water and surfactants on increasing the microemulsions viscosity and the ignition temperature compared to diesel oil. At the same time the low temperature properties of tested microemulsions were less favorable, which may hinder their use in winter conditions.
