    Type: Grant
    Filed: December 22, 2011
    Date of Patent: March 3, 2015
    Assignee: Shell Oil Company
    Inventors: Matthias Eggenstein, Andreas Hugo Brunner

  • METHOD FOR INCREASING THE VISCOSITY OF AUTOMOTIVE FUEL COMPOSITIONS
    Publication number: 20090241882
    Abstract: A certain viscosity index (VI) improving additive may be used to increase the viscosity of an autoamotive fuel composition, by an amount greater than that which theory would have predicted to occur to improve the acceleration performance of an internal combustion engine into which the fuel composition is introduced. 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.
