摘要
通过实验研究了燃用不同乙醇柴油掺混比的乳化燃料对发动机动力性、经济性以及排放特性的影响。实验表明,掺入一定比例的乙醇,对发动机的动力性影响不是很大,但是却可以改善燃烧,提高燃油经济性,显著降低烟度、HC和CO的排放,但随着乙醇掺混比的增加,NOx的排放呈上升趋势,而且这种乳化燃料存在着一个最佳掺混比。
The influences of emulsified fuel in different mix ratio of ethanol-diesel oil on the dynamical efficiency, economical efficiency and the emission of the engine are studied through experiments. The result shows that the dynamical efficiency changes little when the fuel is mixed with a certain proportion of ethanol, but the burning efficiency is greatly improved and the economical efficiency is enhanced. The emission of smoke, HC and CO is remarkably reduced. With the increase of ethanol, the emission of NOx increases. This kind of emulsified fuel has an optimal mix ratio.
