生物降解二冲程油中添加剂对清净性影响的研究

Study on the Influences of Additives on the Detergency of Biodegradable Two Cycle Oil

研究了添加剂对以合成酯为基础油的生物降解二冲程汽油机油(简称二冲程油)清净性的影响。经发动机台架试验,得出如下的结论:金属有灰清净剂有恶化生物降解二冲程油高温清净性的迹象;无灰清净分散剂能够有效地改善生物降解二冲程油高温清净性,但有一个最佳的性能/用量比例;高分子酰胺类与聚酰胺类添加剂复合使用有利于降低成本,提高油品的适应性;中碱、高碱抗粘环添加剂对活塞环粘结和整体清净性都有较大的改善作用,复合使用同样可以提高油品对使用条件的适应性;抗磨添加剂、抗氧剂和降凝剂对生物降解二冲程油的清净性影响不大。

The influence of additives on the detergency of biodegradable two-stroke oil was researched by engine bench tests. It can be concluded that ash-metallic detergents deteriorate the detergency of biodegradable two-stroke oils;nonash detergent-dispersant additives can improve two-stroke oils＇ high-temperature detergency availably, and there is a optimal pertormance/dosage ratio;macromolecule-amide detergents is equivalent with poly-amide detergents in detergency, and it can decrease cost and improve applicability after mixed them;medium/high-alkali anti-stuck-ring additives can decrease stuck-ring and improve detergency preferably, and mixed-using also can improve adaptability;anti-ware, anti-oxygen and pour-point depressant additives have no remarkable influence on detergency of biodegradable two-stroke oils.
