  • Fuel economy
    Patent number: 11578283
    Abstract: Use of a viscosity increasing component in a diesel fuel composition, for the purpose of improving the fuel economy of an engine into which the fuel composition is or is intended to be introduced, or of a vehicle powered by such an engine, wherein the viscosity increasing component is a viscosity index (VI) improving additive, wherein the VI improving additive comprises a linear block copolymer, which contains one or more monomer blocks selected from ethylene, propylene, butylene, butadiene, isoprene and styrene monomers and wherein the VI improving additive is used at a concentration of from 0.001% w/w to 0.05% w/w.
    Type: Grant
    Filed: January 27, 2020
    Date of Patent: February 14, 2023
    Assignee: SHELL USA, INC.
    Inventor: Alastair Graham Smith
  • Fuel compositions
    Patent number: 11499106
    Abstract: A fuel composition comprising a base fuel and at least one viscosity index (VI) improving additive, wherein the viscosity index (VI) improving additive is a functionalized dispersant olefin copolymer. The viscosity index (VI) improving additive provides improved power output and/or acceleration characteristics.
