Title
(EN) Automotive fuel compositions
(ZH) 汽车燃料组合物
Abstract
(EN)
Use of a viscosity index (VI) improving additive, in an automotive fuel composition, for the purpose of improving the acceleration performance of an internal combustion engine into which the fuel composition is introduced. The additive may be used to increase the viscosity of the composition, by an amount greater than that which theory would have predicted to occur. The fuel composition is suitably a diesel fuel composition, and the additive suitably comprises a block copolymer which contains one or more monomer blocks selected from ethylene, propylene, butylene, butadiene, isoprene and styrene monomers. The additive is preferably used in the composition at a concentration of 0.5 %w/w or lower.

(ZH)

粘度指数(VI)改进添加剂在汽车燃料组合物中的用途,其目的是改进所述燃料组合物引入其中的内燃发动机的加速性能。可使用该添加剂提高组合物的粘度,其提高量高于理论预期的发生量。该燃料组合物合适地是柴油燃料组合物,和该添加剂合适地包括含有选自乙烯、丙烯、丁烯、丁二烯、异戊二烯和苯乙烯单体中的一种或多种单体嵌段的嵌段共聚物。优选在组合物中以0.5%w/w或更低的浓度使用该添加剂。
