Analysis of qualitative, environmental and economic indicators of water-fuel emulsions
Modern science and technology opens up new possibilities to improve the performance of internal combustion engines (ICE) and oil saving; when adding water to the fuel mixture - getting water-fuel emulsions (WFE) - concentration of nitrogen oxides and carbon monoxide in the exhaust gas are reduced, possibility of detonation combustion is reduced, engine efficiency is increased. Widespread use of WFE is constrained, first of all, by problems related instability and the inability to long-term storage of emulsions, as well as by the high cost of emulsifiers, increased carbon formation in engines. Consequently, there is a need to assess the quality of the water-fuel emulsion. Described methods for evaluating quality indicators of water-fuel emulsion: homogeneity of the dispersed phase, the time of delamination (settling), the viscosity.
