Fuel additives for lowering deposit and particulate emission

A method for controlling carbon deposits in an internal combustion engine comprising:

• providing a fuel in the internal combustion engine, wherein the fuel comprises:
• i) a hydrocarbon-based fuel boiling in the gasoline or diesel range;
• ii) a carrier fluid comprising an alkyl polyethoxylated having the following structure:
• wherein each R2 and R3 is independently hydrogen, C1-C4 hydrocarbyl group, or C1-C3 alcohol, wherein R1 is C4-C100 hydrocarbyl group, carboxyl group, ether group, thioether group, or aromatic group, wherein x is from 1 to 20,
• or a hydrocarbyl phenol having the following structure:
• wherein R is a hydrocarbyl group from C4-C100;
• iii) an amine-based detergent having the following formula,
• R4—O—(CH2)y—NHR5,
• wherein the amine-based detergent is present in about 10 ppm to about 750 ppm by weight based on total weight of the fuel composition;
• wherein R4 is a hydrocarbyl group having 8 to 20 carbons, R5 is hydrogen or (CH2)zNH2 moiety, and wherein y, z are independently integers having a value of 2 or greater;
• and
• iv) one or more nitrogen-containing detergent.

A concentrate composition comprising:

• about 30 to 90 wt % of an organic solvent boiling in a range of from 65° C. to 205° C. and;
• about 10 to 70 wt % of a detergent mixture comprising:
• i) a carrier fluid comprising an alkyl polyethoxylated having the following structure:
• wherein each R2 and R3 is independently hydrogen, C1-C4 hydrocarbyl group, or C1-C3 alcohol, wherein R1 is C4-C100 hydrocarbyl group, carboxyl group, ether group, thioether group, or aromatic group, wherein x is from 1 to 20,
• or a hydrocarbyl phenol having the following structure
• wherein R is a hydrocarbyl group from C4-C100;
• ii) an amine-based detergent having the following formula,
• R4—O—(CH2)y—NHR5,
• wherein the amine-based detergent is present in about 10 ppm to about 750 ppm by weight based on total weight of the fuel composition;
• wherein R4 is a hydrocarbyl group having 8 to 20 carbons, R5 is hydrogen or (CH2)zNH2 moiety, and wherein y, z are independently integers having a value of 2 or greater;
• and
• iii) one or more nitrogen-containing detergent.
