Abstract

A fuel additive composition comprises (a) a Mannich reaction product and (b) a polyetheramine where the weight ratio on an actives basis of component (a) to component (b) is 1:4-10. A fuel composition and a method for removing intake valve deposits and combustion chamber deposits in a spark-ignited internal combustion engine comprise the fuel additive composition which is very effective in removing the deposits.

First claim

What is claimed is:

1. A fuel additive composition, comprising:
(a) a Mannich reaction product of a hydrocarbyl-substituted phenol wherein the hydrocarbyl substituent has a number average molecular weight of from 500 to 3000, an aldehyde, and an amine; wherein the amine comprises a secondary monoamine; and
(b) a polyetheramine represented by the formula R[OCH 2 CH(R 1 )] n A wherein R is a hydrocarbyl group; R 1 is selected from the group consisting of hydrogen, hydrocarbyl groups of 1 to 16 carbon atoms, and mixtures thereof; n is a number from 2 to about 50; A is —OCH 2 CH 2 CH 2 NR 2 R 2 wherein each R 2 is independently hydrogen or hydrocarbyl; and

the weight ratio on an actives basis of component (a) to component (b) is from 1:5.5 to 1:9.5.

2. The additive composition of claim 1 wherein the hydrocarbyl substituent of component (a) is derived from a polyisobutylene having a vinylidene isomer content of at least 70%.

3. The polyetheramine of the additive composition of claim 1 wherein R has 1 to 30 carbon atoms and is derived from an alcohol, an alkylphenol, or a mixture thereof; R 1 is hydrogen, methyl, ethyl, or a mixture thereof; and n is a number from 10 to 38.

4. The additive composition of claim 3 wherein the hydrocarbyl substituent of component (a) is derived from a polyisobutylene having a vinylidene isomer content of at least 70%.

5. The additive composition of claim 1 , further comprising:
(c) a hydrocarbon solvent.

6. The additive composition of claim 1 , further comprising:
(d) at least one additional additive.

7. A fuel composition, comprising:
a hydrocarbon fuel; and
the additive composition of claim 1 wherein the additive composition is present in the fuel composition on a weight basis at 600 to 10,000 ppm.

8. The fuel composition of claim 7 wherein the hydrocarbon fuel comprises a gasoline.

9. The fuel composition of claim 8 wherein the additive composition is present in the fuel composition on a weight basis at 600 to 4,000 ppm.

10. A method for removing intake valve deposits and combustion chamber deposits in a spark-ignited internal combustion engine, comprising:
operating the engine with the fuel composition of claim 8 .

11. The method of claim 10 wherein the engine has accumulated a service mileage of 10,000 or more miles, the engine has been previously operated on a fuel composition having minimal deposit control performance, or a combination thereof.

12. The composition of claim 1 wherein R has 1 to 30 carbon atoms and is derived from an alcohol, an alkylphenol, or a mixture thereof; R1 is hydrogen, methyl, ethyl, or a mixture thereof; and n is a number from 10 to 38; and wherein A is —OCH2CH2CH2NH2.

13. The composition of claim 1 wherein A is —OCH2CH2CH2NH2; and wherein the composition further comprises (c) a hydrocarbon solvent.

14. The composition of claim 1 wherein R has 1 to 30 carbon atoms and is derived from an alcohol, an alkylphenol, or a mixture thereof; R1 is hydrogen, methyl, ethyl, or a mixture thereof; and n is a number from 10 to 38; and wherein A is —OCH2CH2CH2NH2; wherein the hydrocarbyl substituent of (a) is derived from a polyisobutylene having a vinylidene isomer content of at least 70%; and wherein the amine of component (a) is a secondary monoamine, and A is —OCH2CH2CH2NH2 for the polyetheramine; and wherein the composition further comprises (c) a hydrocarbon solvent.
