Abstract
The present disclosure generally relates to a fuel additive composition for use in reducing corrosion and wear in an internal combustion engine or fuel component part thereof. The fuel additive composition includes a polyetheramine salt obtained by either (a) mixing a polyoxyalkylene monoamine and at least one of a dicarboxylic acid or a tricarboxylic acid or (b) mixing a polyoxyalkylene polyamine and at least one of a monocarboxylic acid, the dicarboxylic acid, or the tricarboxylic acid.
Claims17
A fuel additive composition for reducing corrosion and increasing lubricity in hydrocarbonaceous compositions in contact with a fuel system component part or internal combustion engine comprising a polyetheramine salt obtained by either:
- (a) mixing a polyoxyalkylene monoamine and at least one of a dicarboxylic acid or a tricarboxylic acid;
- or (b) mixing a polyoxyalkylene polyamine and at least one of a monocarboxylic acid, the dicarboxylic acid, or the tricarboxylic acid.
A method for preventing corrosion and wear reduction of a metal, plastic or synthetic part or surface of a fuel system component or internal combustion engine comprising combining an effective amount of the fuel additive composition with a hydrocarbonaceous composition to form a fuel composition, and contacting the metal, plastic or synthetic part or surface with the fuel composition during operation of the engine.
