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.

Process for reducing injector deposits

Use of a wax anti-settling agent (WASA), in an automotive fuel composition, for the purpose of improving the acceleration performance of an internal combustion engine into which the fuel composition is or is intended to be introduced or of a vehicle powered by such an engine.

Use of a wax anti-settling additive in automotive fuel compositions

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.

Fuel composition

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: &#x2022;at least one bicyclic (meth)acrylate ester &#x2022;optionally at least one lower-alkyl (meth)acrylate, &#x2022;optionally at least one aromatic vinyl monomer, and &#x2022;optionally other ethylenically unsaturated monomers.

A fuel composition for powering a combustion engine the composition comprising: a liquid base fuel; and a copolymer obtainable by copolymerizing at least the following monomers: &#x2014;at least one bicyclic (meth)acrylate ester; &#x2014;at least one fatty-alkyl (meth)acrylate; &#x2014;optionally, and preferably, at least one aromatic vinyl monomer; and &#x2014;optionally other ethylenically unsaturated monomers.
