USE OF VISCOSITY INDEX IMPROVING ADDITIVES FOR ENHANCING THE ACCELERATION PERFORMANCE OF INTERNAL COMBUSTION ENGINES |
摘要 |
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 maybe 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. |
