Solid additive composition and method thereof

摘要

An additive composition comprises (A) an additive comprising a nitrogen-containing detergent, a fatty acid based friction modifier, or a mixture thereof and (B) a solid organic matrix material where the additive composition is a solid that melts in the range of about 25 to about 200° C. A method to enhance performance of a functional fluid, especially a fuel composition or power transmission fluid of a vehicle powered by an internal combustion engine, comprises adding a performance-enhancing amount of the additive composition to the functional fluid.
