Abstract:
An additive composition for a fuel oil composition and that is free of polycyclic carboxylic acids and of acid derivatives thereof comprises an additive that comprises one or more monocarboxylic acids, each having from 10 to 24 carbon atoms, or acid derivatives thereof, optionally in combination with one or both of an anti-oxidant additive and an anti-static additive.
Abstract:
An improved fuel additive formulation, method of use, and method of producing the fuel formulation are described. The improved fuel additive of the present invention comprises a mixture of nitroparaffins (comprising nitromethane, nitroethane, and nitropropane), and a combination of modified commercially available ester oil and/or a solubilizing agent, and/or toluene. The ratio of ester oil and/or solubilizing agent and/or toluence to nitroparaffin is preferably less than 20 volume percent, with nitroparaffins comprising the balance of the additive. A method of preparing and using the additive formulation is also provided.
Abstract:
A fuel composition is provided that contains a major amount of a mixture of hydrocarbons in the gasoline boiling range and a minor amount of a certain aniline additive compound. Use of such aniline additive compound in a combustion engine is also provided.
