Abstract: Provided are octane enhancing additives and methods that improve a liquid fuel composition's octane rating. A liquid fuel composition may comprise a liquid fuel and an octane enhancing additive. The octane enhancing additive may comprise an indoline compound with a bicyclic ring structure, wherein the indoline compound comprises a six-membered aromatic ring and a five-membered aliphatic ring that share a carbon-carbon aromatic bond. The five-membered aliphatic ring may be heterocyclic and may comprise a nitrogen positioned in an alpha position to the six-membered aromatic ring.

Abstract: GDI deposit fluidizing additives, liquid fuel compositions including such additives and methods that improve a liquid fuel composition's GDI performance are provided. A liquid fuel composition may include a major amount of a base gasoline fuel; and 1 to 500 ppm of one or more polyether monohydroxy compounds, with the proviso that the liquid fuel composition is essentially free of fuel detergent additives. The liquid fuel composition provides at least 10% lower particulate emission as a function of time relative to a comparable liquid fuel composition not including the one or more polyether monohydroxy compounds. The GDI deposit fluidizing enhancing additive may include polyether monohydroxy compounds with the butane oxide and propene oxide in a variety of ratios and randomly distributed in the additive.

Abstract: Fuel compositions for advanced combustion engines that include a naphtha boiling range portion are provided, where the fuel compositions can have a reduced ignition delay and/or an improved derived cetane number. The improved combustion properties can be achieved by adding a portion of a light naphtha (boiling range) composition to a heavy naphtha boiling range composition. The addition of up to about 10 vol % of a light naphtha composition to a heavy naphtha composition can result in a mixture having a reduced ignition delay relative to the heavy naphtha composition.
