  • PROCESS FOR REDUCING INJECTOR DEPOSITS
    Publication number: 20220401895
    Abstract: A process for reducing injector deposits in an internal combustion engine fuelled with a fuel composition, the process comprising contacting a fuel composition with a metal-selective membrane situated in the fuel delivery system. The reduction of such deposits provides an increase in fuel efficiency, fuel thermal stability, boost in engine cleanliness, improves fuel economy and enables the possibility of using a reduced amount of expensive detergent in the fuel composition.

  • Fuel composition
    Patent number: 11254885
    Abstract: A fuel composition for powering a combustion engine, the composition comprising a liquid base fuel; and a (co)polymer obtainable by (co)polymerizing at least the following monomers: one or more bicyclic (meth)acrylate esters (a); up to 15 wt % of styrene (b); optionally other ethylenically unsaturated monomers that are not monomer (a) or (b); up to a total of 100 wt %, wherein the weight percentages of the monomer are based on the total weight of all of the monomers.
