  A new friction modifier system is described. It has the capability of establishing and maintaining a substantially constant static breakaway coefficient of friction between a pair of friction surfaces that are periodically frictionally engaged with each other. Also this system is capable of maintaining a substantially constant ratio between (i) the low speed dynamic coefficient of friction of such friction surfaces, and (ii) the (midpoint) dynamic coefficient of friction of such friction surfaces. The additive composition yielding these results comprises at least the following components: a) a hydroxyalkyl aliphatic imidazoline in which the hydroxyalkyl group contains from 2 to 4 carbon atoms, and in which the aliphatic group is an acyclic hydrocarbyl group containing from 10 to 25 carbon atoms; and b) a di(hydroxyalkyl) aliphatic tertiary amine in which the hydroxyalkyl groups, being the same or different, each contain from 2 to 4 carbon atoms, and in which the aliphatic group is an acyclic hydrocarbyl group containing from 10 to 25 carbon atoms.

  本文介绍了一种新型摩擦改进系统。它能够在一对周期性相互摩擦的摩擦表面之间建立并保持基本恒定的静态分离摩擦系数。此外，该系统还能使 (i) 摩擦表面的低速动态摩擦系数和 (ii) 摩擦表面的（中点）动态摩擦系数之间的比率保持基本恒定。产生这些结果的添加剂组合物至少包括以下成分：a) 羟烷基脂肪族咪唑啉，其中羟烷基含有 2 至 4 个碳原子，脂肪族基团是含有 10 至 25 个碳原子的无环烃基基团；以及 b) 二（羟烷基）脂肪族叔胺，其中羟烷基（相同或不同）各含有 2 至 4 个碳原子，脂肪族基团是含有 10 至 25 个碳原子的无环烃基基团。
