Abstract
Paper presents research results of selected physicochemical properties of water – fuel microemulsion, which can be used as a fuel for a diesel engines. Researches were carried out for a diesel oil blended with selected surfactants and water at 4 and 8 % by weight. Tested microemulsions contained a two kinds of nonionic surfactants, ie., lauryl alcohol ethoxylates with 3 moles of ethylene oxide (Laureth - 3) and a lauryl alcohol ethoxylates with 7 moles of ethylene oxide (Laureth - 7). The addition of these chemicals and water to the diesel oil allows to formulate a fuel microemulsions marked by a code L4 and L8. The particle diameter of the dispersed phase in the diesel oil is in the range of 4-100 nm. For this reason, 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 wereless favorable, which may hinder their use in winter conditions.
