柴油添加剂功效影响因素的灰色关联分析(英文)

Application of Grey Relation Analysis for Factors Influencing Efficacy of Diesel Oil Additives

提出了一种柴油添加剂非台架实验的功效判断方法———灰色关联分析法。应用这个方法分析待测功效的柴油添加剂,可通过测定加入它后的柴油样品的物理性质和加入已知功效较好的柴油添加剂的柴油样品的物理性质,再作灰色关联分析,综合关联顺序以评定其功效好坏。应用这个方法还可推断柴油样品的表面张力是影响燃烧好坏的主要因素,其次是粘度、十六烷值和燃点。

A kind of efficacy evaluating method for diesel oil additives without requiring engine test is developed, namely grey relation analysis method. This method can analyze diesel oil additive whose efficacy is unknown. It only takes some simple physical property tests of the diesel oil samples added unevaluated diesel oil additive or a kind of known better diesel oil additive to do the grey relation analysis and evaluate the unevaluated additive. This method can help us to conclude that the surface tension of the samples is the main factor that influences their combustion, then the viscosity, the cetane number and the ignition point.
