A cleaning system is provided to reduce, minimize, or eliminate deposits located within gaseous intake, processing, and emissions portions of a vehicle engine. The cleaning system includes use of a cleaning composition for removing such deposits. The cleaning composition can include water; a nitrogen-based dispersant or cleaner; a surfactant; a C6-C18 alcohol; a glycol ether; and an organic acid.

1. An aqueous-based cleaning composition for removal of engine deposits, comprising: about 0.5 vol % to about 10.0 vol % of a nitrogen-based dispersant;about 0.25 vol % to about 4.0 vol % of a surfactant;about 2 vol % to about 12 vol % of an C6 to C18 alcohol;about 2 vol % to about 30 vol % of a gly
1. An aqueous-based cleaning composition for removal of engine deposits, comprising: about 0.5 vol % to about 10.0 vol % of a nitrogen-based dispersant;about 0.25 vol % to about 4.0 vol % of a surfactant;about 2 vol % to about 12 vol % of an C6 to C18 alcohol;about 2 vol % to about 30 vol % of a glycol ether;about 0.25 vol % to about 4.0 vol % of a C2 to C18 organic acid; andabout 30 vol % to about 95 vol % water. 2. The aqueous-based cleaning composition of claim 1, wherein the C6 to C18 alcohol is tetrahydrofuryl alcohol. 3. The aqueous-based cleaning composition of claim 1, wherein the glycol ether is dipropylene glycol methyl ether, diethylene glycol butyl ether, or a combination thereof. 4. The aqueous-based cleaning composition of claim 1, wherein the C2 to C18 organic acid is ethylhexanoic acid. 5. The aqueous-based cleaning composition of claim 1, wherein the surfactant is an alcohol ethoxylate. 6. The aqueous-based cleaning composition of claim 1, wherein the nitrogen-based dispersant is morpholine, a morpholine derivative, aminopropylmorpholine, benzyl amine, lauryl amine, isononyl amine, oleyl amine, or a combination thereof. 7. The aqueous-based cleaning composition of claim 1, wherein the composition comprises at least about 5 vol % of the C6 to C18 alcohol, about 6 vol % or less of the nitrogen-based dispersant, about or less of the C2 to C18 organic acid, or about 2 vol % or less of the surfactant. 8. The aqueous-based cleaning composition of claim 1, wherein the composition comprises at least about 5 vol % of the C6 to C18 alcohol, about 6 vol % or less of the nitrogen-based dispersant, about 2 vol % or less of the C2 to C18 organic acid, and about 2 vol % or less of the surfactant. 9. The aqueous-based cleaning composition of claim 1, wherein the composition further comprises at least one additional component. 10. The aqueous-based cleaning composition of claim 1, wherein the composition comprises at least about 10 vol % of the glycol ether. 11. An aqueous-based cleaning composition for removal of engine deposits, comprising: about 0.5 vol % to about 10.0 vol % of a morpholine, a morpholine derivative, aminopropylmorpholine, benzyl amine, lauryl amine, isononyl amine, oleyl amine, or a combination thereof;about 0.25 vol % to about 4.0 vol % of an alcohol ethoxylate surfactant;about 2 vol % to about 12 vol % of a C6 to C18 alcohol;about 2 vol % to about 30 vol % of a C6 to C12 glycol ether;about 0.25 vol % to about 4.0 vol % of a C2 to C18 organic acid; andabout 40 vol % to about 95 vol % water. 12. The aqueous-based cleaning composition of claim 11, wherein the C6 to C18 alcohol is tetrahydrofuryl alcohol. 13. The aqueous-based cleaning composition of claim 11, wherein the C6 to C12 glycol ether is dipropylene glycol methyl ether, diethylene glycol butyl ether, or a combination thereof. 14. The aqueous-based cleaning composition of claim 11, wherein the C2 to C18 organic acid is ethylhexanoic acid. 15. A method of cleaning an engine, comprising: introducing a cleaning composition into an air intake system, a turbocharger, a hot exhaust gas recirculation system, or a combination thereof of the engine, the cleaning composition comprising: about 0.41 vol % to about 10.0 vol % of a nitrogen-based dispersant;about 0.25 vol % to about 4.0 vol % of a surfactant;about 2 vol % to about 12 vol % of an C6 to C18 alcohol;about 2 vol % to about 30 vol % of a glycol ether;about 0.25 vol % to about 4.0 vol % of a C2 to C18 organic acid; andabout 40 vol % to about 95 vol % water. 16. The method of claim 15, wherein the cleaning composition is introduced into the engine while the engine is running. 17. The method of claim 16, wherein the cleaning composition is heated to a temperature of about 100° F. to about 212° F. prior to introducing the cleaning composition into the engine. 18. The method of claim 15, wherein the cleaning composition is introduced into the engine at an ambient temperature. 19. The method of claim 15, wherein the cleaning composition further comprises an additional component. 20. The method of claim 15, wherein the cleaning composition comprises about 0.5 vol % to about 6.0 vol % of a morpholine, a morpholine derivative, aminopropylmorpholine, benzyl amine, lauryl amine, isononyl amine, oleyl amine, or a combination thereof;about 0.25 vol % to about 2.0 vol % of an alcohol ethoxylate surfactant;about 5 vol % to about 12 vol % of a C6 to C18 alcohol;about 10 vol % to about 30 vol % of a C6 to C12 glycol ether;about 0.25 vol % to about 4.0 vol % of a C2 to C18 organic acid; andabout 45 vol % to about 84 vol % water.
