  • Patent number: 8911517
    Abstract: An additive for gasoline, especially gasoline containing ethanol in an amount of up to about 15%, reduces the potential for phase separation of water from the gasoline. The additive has two components. The first component consists essentially of glycol butyl ether. The second component consists essentially of nonylphenol polyethylene glycol ether with minor amounts of polyethylene glycol and dinonylphenyl polyoxyethylene. Typically, the additive has the first component present in an amount in the range of from about 90 to about 95% by volume, with the balance being the second component. The additive is effective when added to the gasoline in an amount in the range of from about 0.52% to 0.63% by volume.

  • Patent number: 5242469
    Abstract: A gasoline additive composition comprising an ester; and at least one dispersant component chosen from the group consisting of a specified monosuccinimide, a specified bissuccinimide, an alkylamine of average molecular weight 500-5000 having a polyolefine polymer as an alkyl group and a specified benzylamine derivative of average molecular weight 500-5000. It can contain a polyoxyalkylene glycol or its derivative. It can further contain a lubricant oil fraction of viscosity in the range 3-35 mm.sup.2 /s (100.degree. C.) It prevents undesired deposits on the surfaces of intake valves of an automobile engine.

  • Patent number: 5183476
    Abstract: A fuel which is ethanol-based and which has the form of a solution includes from 62-94% by weight of ethanol; from 2-8% by weight of water; from 2-30% by weight of an ignition improving agent comprised of a water-soluble polyalkylene glycol compound containing 6-50 alkyleneoxy units with 2-4 carbon atoms and having a molecular weight of less than 2500. Such fuel is useful for fueling diesel engines and has excellent combustibility while emitting a low content of organic hydrocarbons. At the same time, the polyalkylene glycol ignition improving agent is odorless, non-toxic, stable in storage, and does not emit nitrogen oxides when combusted.
