Abstract
A fuel additive for a gasoline fuel composition, a gasoline fuel composition and a method for reducing wear in a gasoline delivery system of an engine. The fuel additive includes a synergistic mixture of (i) N,N-bis(hydroxyalkyl)-alkylamine, and (ii) an amide reaction product of a hydroxy acid, hydroxy ester, or lactone and an amine or ether amine, wherein a weight ratio of (i) to (ii) in the synergistic mixture ranges from about 1:5 to about 5:1.
Claims19
A fuel additive for a gasoline fuel composition comprising a synergistic mixture of (i) N,N-bis(hydroxyalkyl)-alkylamine, and (ii) an amide reaction product of a hydroxy acid, hydroxy ester or lactone and an amine or ether amine, wherein a weight ratio of (i) to (ii) in the synergistic mixture ranges from about 1:5 to about 5:1.
A gasoline fuel composition for reducing fuel system component wear comprising gasoline and a fuel additive mixture of (i) N,N-bis(hydroxyalkyl)-alkylamine, and (ii) an amide reaction product of a hydroxy acid, hydroxy ester or lactone and an amine or ether amine, wherein a weight ratio of (i) to (ii) in the fuel additive mixture ranges from about 1:5 to about 5:1.
A method for reducing wear in a fuel delivery system of a gasoline engine, comprising:
- providing gasoline containing a wear reducing additive mixture consisting essentially of (i) N,N-bis(hydroxyalkyl)-alkylamine, and (ii) an amide reaction product of a hydroxy acid, hydroxy ester, or lactone and an amine or ether amine, wherein a weight ratio of (i) to (ii) in the additive mixture ranges from about 1:5 to about 5:1;
- combining the additive mixture with gasoline to provide a fuel composition;
- and
- operating the engine on the fuel composition.
