现代汽油机油基础油和添加剂

Base oil and additives for modern gasoline engine lube

汽油机油的质量和使用性能随着现代汽油机的设计和驾驶工况的变化以及环保节能的要求而不断发展 ,相应地对基础油和添加剂也提出更高的要求。通过对球锈蚀试验 ( BRT)、氧化安定性试验 ( TFOUT)、程序 VE油泥生成和阀系磨损试验的试验数据进行科学分析 ,考察了基础油和添加剂对现化汽油机油的影响及它们之间的协和作用。结果表明 ,为了满足现代汽油机油性能的要求 。

The gasoline engine lube is developing along with the modernization of automobile design, the harsh of drive condition and the stringency of the emission regulations. Thus the stricter requirements to base oil and additives are put forward. Investigated the influence of the base oil and additives to the modern gasoline engine and the compatibility among the additives base on the data of the tests include those of ball rust test, oxidation stability test, greasy filth formation and valve wearing test of VE sequence. Research indicates that the base oil and additives must be carefully investigated and balanced in order to meet the demands of modern gasoline engine lube performance.
