Biodiesel is easy to crystallize under low-temperature because of high solidification point (SP) and high cold filter plugging point (CFPP).
然而生物柴油凝点和冷滤点很高，低温情况下容易结晶析出，堵塞发动机的管道和过滤器而无法正常使用。
Some cold flow improvers with excellent performance for diesel fuel were selected by evaluating the cold flow improvers and investigating the receptivity of CFPP of diesel fuel to cold flow improver.
通过对柴油降凝剂的筛选评价和对不同降凝剂冷滤点感受性的考察，选择出性能优良的柴油降凝剂。
