摘　　要：分析了国内外燃油乳化、燃烧技术以及燃油静电雾化的应用与研究情况。从乳化燃油雾化质量与燃烧特性的角度,认为限制该技术进一步全面推广使用的原因为燃油乳化之后的雾化阻力增大引起的雾化质量下降以及固定的掺水比例的乳化燃油无法解决柴油机低负荷不稳定和高负荷高排放的难题。在此基础上首次提出了将静电雾化技术与燃油乳化燃烧技术相结合的构想,并结合国内外研究情况,分析了这2种先进的燃烧技术相结合的可行性以及对节能减排的应用价值。The latest application, research and development of emulsified fuel and different kinds of fuel electrostatic atomization combustion are reviewed respectively. In the view of the characteristics of the atomization and combustion of emulsified fuel, the two causes limiting this technique to further popularize are analyzed. Firstly, the surface tension and viscosity of the fuel are highly increased after the emulsification, as a result, the atomization resistance will increase highly to lower its atomization quality if the atomization configure and operational parameters are kept the same; secondly, the emulsified fuel of fixed ratio of fuel to water makes diesel engines run unstably in case of low workload, and increase exhaust pollution in case of high workload. With the above two troublesome problems in consideration two kinds of advanced combustion techniques is brought forward. The feasibility of the combination and its value in energy saving and emission reduction are analyzed.
