    摘要: A fuel additive composition comprising a sustained release component and an additive component, the additive component is effective to provide at least one benefit to a fuel when released into the fuel, the sustained release component is (1) a polymeric material, (2) substantially insoluble in the fuel, and (3) effective to reduce the rate of release of the additive component into the fuel relative to an identical composition without the sustained release component.

    摘要: This invention relates to a fuel filter for use with internal combustion engines. The fuel filter includes a fuel additive that can be released into fuel. The rate of release for the fuel can be controlled. In one form the fuel additive can be mixed with a matrix material and released at a substantially constant rate to maintain a uniform level of fuel additive in the fuel. Use of the present invention provides a fuel filter having an extended life span that is longer than fuel filters typically used with combustion engines.

    摘要: A container for releasing a chemical additive into a fuel composition comprises a fuel-impermeable casing having a hollow interior and an additive composition comprising at least one fuel soluble additive. The additive is held within the container by at least one fuel-permeable element provided at or near an opening in the casing and is effective to provide for release of additive(s) into the fuel composition. Methods of releasing additives into fuel compositions are also provided.
