1.运动黏度 Kinematic viscosity(50°C):

\

测试意义:

油品分级的依据;
粘度直接影响输送性能好柴油机的喷油雾化效果;
粘度过高,增大泵送沿程阻力,影响喷油油束的形成,造成雾化不良,不能与空气均匀混合,致使燃烧不完全,甚至形成积炭;
粘度过低,油束角度过大,同样不能喷射到设计的位置与空气良好混合,也会导致燃烧不完全,功率下降。

2.闪点 Flash Point:

\

测试意义:

衡量油品在储存、运输和使用过程中的安全性指标,表示油品着火燃烧的危险程度;
是对易燃易爆危险品进行分级的主要依据;
可以根据闪点来判断馏分燃料的轻组成分;
根据闪点来可以判断燃料油是否被轻组分污染;产品里含有挥发性组分时闪点会迅速减低。

3. 密度 Density(20°C):

\

测试意义:

是计算装载量和进行贸易量交接换算的重要指标;
密度大小与燃料油的化学成分和馏分组成有关,可依据密度初步判定油品的品种及质量,如通常来说,密度高而其热值相对较低。

4.水分 Water:
