A fuel additive and method for improving fuel economy in an engine. The method includes providing a fuel composition to an engine, wherein the fuel composition includes gasoline and from 10 to 750 ppm by weight based on a total weight of the fuel composition of a fuel stable additive of the formula:
wherein R1 comprises a saturated hydrocarbyl group having from 6 to 30 carbon atoms, R2 is an alkylene, polyalkylene, alkoxyalkylene or polyalkoxyalkylene group containing from 2 to 25 carbon atoms, R3 is an alkylene group containing from 2 to 5 carbon atoms, R4 is a linear alkyleme group containing 2 to 3 carbon atoms, and x is an integer selected from 0 and 1, and combusting the fuel composition in the engine.
一种提高发动机燃油经济性的燃料添加剂和方法。该方法包括向发动机提供一种燃料组合物,其中燃料组合物包括汽油和按燃料组合物总重量计算的 10 至 750 ppm 的配方燃料稳定添加剂:
其中 R1 是具有 6 至 30 个碳原子的饱和烃基,R2 是含有 2 至 25 个碳原子的亚烷基、聚亚烷基、烷氧基亚烷基或聚烷氧基亚烷基,R3 是含有 2 至 5 个碳原子的亚烷基,R4 是含有 2 至 3 个碳原子的线性烷基,x 是选自 0 和 1 的整数,然后将燃料组合物在发动机中燃烧。
