用于在内燃机中减少活塞环结垢的润滑剂组合物
摘要：
本发明涉及适合于在内燃机中减少活塞环结垢的润滑剂组合物，其包含基础油或基础油调和物和一种或多种添加剂，其中所述润滑剂组合物具有大于5.0mm2/s(cSt)的100℃下运动粘度，小于9500mPas(cP)的根据ASTM D 5293测定的－15℃下冷机起动模拟动态粘度，和小于60000mPas的根据ASTM D 4684测定的－20℃下微型旋转粘度测试值，并且其中所述基础油或基础油调和物得自蜡质链烷属费托合成的烃馏分，并包含具有n、n+1、n+2、n+3和n+4个碳原子的异链烷烃的连续系列，其中n在15和35之间。
摘要（英）：

The present invention relates to a lubricant composition comprising a base oil or base oil blend and one or more additives, wherein the lubricant composition has a kinematic viscosity at 100 DEG C of more than 5.0 mm/s (cSt), a cold cranking simulated dynamic viscosity at -15 DEG C according to ASTM D 5293 of less than 9500 mPas (cP) and a mini rotary viscosity test value of less than 60000 mPas at -20 DEG C according to ASTM D 4684, and wherein the base oil or base oil blend has been obtained from a waxy paraffinic Fischer-Tropsch synthesized hydrocarbon fraction and comprises a continuous series of isoparaffins having n, n+1, n+2, n+3 and n+4 carbon atoms, wherein n is between 15 and 35, suitable for the reduction of piston ring fouling in an internal combustion engine.
