乳化燃油的特性及其在内燃机中的应用研究

随着能源短缺、环境污染的日益严峻 ,研究开发新型代用燃料成为解决这一问题的主要途径之一 在内燃机中燃用掺水乳化燃油不但可以取得良好的节油效果 ,而且可以大幅度降低氮氧化物、固体颗粒物等有害物质的排放量 ,因此被视为一种降低油耗、改善排放的有效手段 但乳化油的稳定性差、在掺水量较大时难以保证柴油机的正常着火起动又是推广燃油乳化技术需要解决的问题 根据多年来国内外学者所作的研究 ,就乳化油的稳定性、节油机理、降低排放机理以及着火延迟等问题的研究现状进行综合评述 ,对今后的研究工作具有一定的参考价值

Study on Characteristics of Emulsified Oil and Its Application to I.C. Engines

Due to the shortage of oil resources and pollution of the environment, using substitutive fuels becomes urgent for solving those problems.Using Emulsified oil in internal combustion engine can not only decrease fuel consumption but also lessen NO x and particulates emissions greatly. So it has been recognized as an efficient method to lower fuel consumption and emissions in internal combustion engine. However, there exists a problem that emulsified oil has poor stability and the I.C. engine is not easy to start when emulsified oil contains excessive water. By referring to the work of the previous researchers, this paper fully describes present research stage of several problems, such as the stability of emulsified oil, the mechanisms of saving fuel and lowering emissions, as well as the ignition delay. The paper provides useful reference for further research
