Abstract:
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.
Abstract:
A liquid fuel composition containing (a) a diesel base fuel suitable for use in an internal combustion engine; and (b) one or more organic sunscreen compounds. The liquid fuel composition of the present invention provides benefits in terms of power output of a diesel engine, and modifying the ignition delay and/or modifying the burn period and/or increasing the cetane number of the liquid fuel composition.

Abstract:
A liquid fuel composition containing (a) a gasoline base fuel suitable for use in an internal combustion engine; and (b) one or more organic sunscreen compounds. The liquid fuel composition of the present invention provides benefits in terms of improved acceleration and/or power output of an internal combustion engine fuelled by said fuel as well as an increase in flame speed.
Abstract:
Use of a hydrocarbyl-substituted dicarboxylic acid for improving or boosting the separation of water from fuel oils and gasoline fuels which comprise additives with detergent action. A Fuel additive concentrate comprising the said hydrocarbyl-substituted dicarboxylic acid, certain additives with detergent action and optionally other customary additives and solvents or diluents.
Abstract:
A liquid fuel composition comprising a base fuel suitable for use in an internal combustion engine; one or more organic UV filter compounds; and one or more ester co-additive compounds provides improvements in terms of stability properties in an additive blend containing said one or more organic UV filter compounds and said one or more ester co-additive compounds, particularly at low temperatures, such as temperatures of 5° C. or lower.
Abstract:
Compositions including at least three metals (M1, M2, M3) are disclosed. The first metal (M1) is at least one metal selected from the iron group or the manganese group, and is preferably selected from iron, manganese, cobalt and nickel. The second metal (M2) is at least one metal selected from the rare earth group and is preferably selected from cerium, lanthanum, neodymium and praseodymiium. The third metal (M3) is selected from the group of alkaline or alkaline-earth metals, and is preferably selected from barium, strontium, calcium and lithium. The weight ratio (R) of metal (M3) to metal (M2) is greater than 0.15, and preferably greater than 1.5.
Abstract:
A fuel composition for spark-ignition engines consisting essentially of gasoline and a barium compound in an amount of 100 ppm or more in terms of barium metal and relative to the gasoline, said barium compound being selected from the group consisting of a barium sulfonate, a barium naphthenate, a barium alkylsalicylate and a barium .alpha.-alkylalkane monocarboxylate. Spark-ignition engines utilizing this fuel composition operate with improved characteristics relative to adhesion of carbon to the spark plugs. The exhaust from the engine does not degrade the exhaust gas purifying catalyst even when the engine is equipped with an exhaust ignition control device.
Abstract:
This invention relates to basic magnesium salts of substituted aromatic hydroxy carboxylic acids or the derivatives thereof and to a process for preparing such salts. These salts can be used either along or in combination, as additives, in a variety of lubricating oils and fuels including gasoline, diesel fuels, etc.
