Abstract
The present disclosure provides fuel additives including quaternary ammonium salt additive(s) and Mannich detergent additive(s) effective to improve engine performance in both port fuel injected and gasoline direct injection engines.
Claims18
A fuel additive package for a spark-ignition engine comprising:
- a Mannich detergent including the reaction product of a hydrocarbyl-substituted phenol, one or more aldehydes, and one or more amines, wherein the Mannich detergent has the structure of Formula I:
- wherein R1 is hydrogen or a C1 to C4 alkyl group, R2 is a hydrocarbyl group having a number average molecular weight of about 500 to about 3000, R3 is a C1 to C4 alkylene or alkenyl group, and R4 and R5 are, independently, hydrogen, a C1 to C12 alkyl group, or a C1 to C4 alkyl amino C1-C12 alkyl group;
- a quaternary ammonium salt additive having the structure of Formula II
- [(R10)(R11)N—(CH2)n—Xm—(CH2)n—Xm—(CH2)n—N⊕(R7)(R8)(R9)]M⊖ (Formula II)
- wherein each X is a bivalent moiety selected from the group consisting of —O—, —N(R12)—, —C(O)—, —C(O)O—, or —C(O)NR12;
- each R7, R8, and R9 are independently alkyl groups containing 1 to 8 carbon atoms;
- R10 and R11 are independently selected from hydrogen, an alkyl group, an acyl group, or a hydrocarbyl substituted acyl group, the hydrocarbyl substituent of one or both of R10 and R11 having a number average molecular weight of about 700 or greater;
- R12 is independently a hydrogen or a group selected from C1-6 aliphatic, phenyl, or alkylphenyl;
- each m is independently an integer of 0 or 1 with at least one m being 1;
- each n is independently an integer of 1 to 10;
- and M⊖ is a carboxylate;
- an alkoxylated alcohol, wherein a weight ratio of the alkoxylated alcohol to the Mannich detergent is about 0.8 or less, wherein the alkoxylated alcohol is a polyether having the structure of Formula Va:
- wherein R6 is an aryl group or a linear, branched, or cyclic aliphatic group having 5 to 50 carbons, R7 is a C1 to C4 alkyl group, and n is an integer from 5 to 100;
- wherein a weight ratio of the Mannich detergent to the quaternary ammonium salt additive is about 4:1 to about 10:1;
- and
- wherein the fuel additive package includes about 20 to about 70 weight percent of the Mannich detergent, about 1 to about 20 weight percent of the quaternary ammonium salt additive, and about 5 to about 30 weight percent of the alkoxylated alcohol.

A gasoline fuel composition comprising
- about 55 to about 125 ppmw of a Mannich detergent including the reaction product of a hydrocarbyl-substituted phenol, one or more aldehydes, and one or more amines, wherein the Mannich detergent has the structure of Formula I:
- wherein R1 is hydrogen or a C1 to C4 alkyl group, R2 is a hydrocarbyl group having a number average molecular weight of about 500 to about 3000, R3 is a C1 to C4 alkylene or alkenyl group, and R4 and R5 are, independently, hydrogen, a C1 to C12 alkyl group, or a C1 to C4 alkyl amino C1-C12 alkyl group;

- wherein each X is a bivalent moiety selected from the group consisting of —O—, —N(R12)—, —C(O)—, —C(O)O—, or —C(O)NR12;
- each R7, R8, and R9 are independently alkyl groups containing 1 to 8 carbon atoms;
- R10 and R11 are independently selected from hydrogen, an alkyl group, an acyl group, or a hydrocarbyl substituted acyl group, the hydrocarbyl substituent of one or both of R10 and R11 having a number average molecular weight of about 700 or greater;
- R12 is independently a hydrogen or a group selected from C1-6 aliphatic, phenyl, or alkylphenyl;
- each m is independently an integer of 0 or 1 with at least one m being 1;
- each n is independently an integer of 1 to 10;
- and M⊖ is a carboxylate;
- and
- about 15 to about 40 ppmw of an alkoxylated alcohol, wherein a weight ratio of the alkoxylated alcohol to the Mannich detergent is about 0.8 or less, wherein the alkoxylated alcohol is a polyether having the structure of Formula Va:
- wherein R6 is an aryl group or a linear, branched, or cyclic aliphatic group having 5 to 50 carbons, R7 is a C1 to C4 alkyl group, and n is an integer from 5 to 100;
- and
