Definitions
- Gasoline direct injected engines directly add fuel to the combustion chamber bypassing the intake valves for efficient combustion. Some of the exhaust and crankcase vapor gas is recirculated back to the air intake and over the intake valves. This can cause a buildup of a carbonaceous material on and around the manifold and air intake valves, which eventually decreases fuel efficiency and performance.
- a cleaning composition is used to clean intake valves of gasolineengines by injecting the cleaning composition into the air intake of the engine as the engine is running.
- the cleaning composition dissolves and removes the oily carbonaceous buildup on the intake valves.
- the cleaning composition uses a solvent/surfactant with fuel value and organic carriers for use in gasoline engines.
- the cleaning composition of the present invention used for gasoline engines includes anon-aqueous organic carrier, an organic solvent which has a high solvency and no fuel value, along with an appropriate surfactant and a wetting agent.
- the organic solvent also referred to as a surfactant/solvent used in the present invention must have a high solvency effective to dissolve oil, such as the oil in the carbonaceous buildup on the intake valves.
- Solvency can be defined by either the Kauri- butanol value or the Hansen solubility parameter.
- the organic solvent When defined by the Kb value, which is measured by ASTM D1 133, the organic solvent should have a solvency of at least 100 and more typically 500, 1000 or higher than 1000.
- Hansen solubility parameters There are three different Hansen solubility parameters: the dispersive parameter; the polar parameter; and the hydrogen bonding parameter.
- the polar parameter is more predictive of the ability of the solvent to dissolve oily compositions.
- the polar parameter should be at least 6, preferably 6.4 or higher, such as 9.5 or greater.
- Solvents with either the high Kb value or high polar Hansen solubility parameter can be used in the present invention.
- One such solvent is Steposol® SC from Stepan Company.
- Another such solventisOmnia from Eastman Chemical Co.
- Another such solvent is TomaKleen G-12 from Air Products and Chemicals, Inc.
- Another such solventisRadia 7543 from Oleon.Other such solvents includeVertecBioElsolTR and VertecBio Clean ECO-Solv from VertecBioSolvents.
- the high solvency organic solvent should have fuel value to make it suitable for use in a gasolineengine.
- the carrier must combust in the gasolineengine.
- the spark generated by the spark plug of the gasolineengine should cause the organic solvent to combust.
- One type of high solvency organic solvent suitable for the present invention is an alkyl substituted fatty amide such as an N,Ndialkyl fatty acid amide, in particular, N,N- Dimethyl-9-decenamide.
- This organic solvent has a solvency greater than 1000 and also has the following Hansen solubility parameters:dispersive: 16.58, polar: 9.58, and hydrogen bonding: 8.45.
- One such alkyl substituted fatty amide is Steposol® MET-IOU from Stepan Company.
- Another suitable organic solvent is an alkyl hydroxy butyrate.
- butyl - 3-hydroxybutyrate This organic solvent has a solvency greater than 100 and further has Hansen solubility parameters of dispersive: 16.13, polar: 6.541, and hydrogen bonding: 1 1.52.
- the cleaning composition of the present invention will include 1.0 to 90% by weight of the organic solvent.More particularly, embodiments may includeO.5 to 50%, or 2 to 20%, such as 2, 3, 4, 5, 6, 7, 8, 9, 10, 15 or 20% by weight of the organic solvent.
- the cleaning composition will have anon-aqueous organic carrier as well as a surfactant which combine to form a stable solution.
- a carrier suitable for use in the present invention is n-propyl propionate, which is a flammable carrier.
- n-propyl propionate is sold by Eastman Chemical Company.
- Suitable carriers include pentyl propionate, n-butyl propionate, isobutyl isopropionate and glycol ether EB.
- the amount of carrier will form the balance of the formulation up to 100%.
- the carrier will comprise 0.1 to 99% by weight, generally 50-90% of the total composition.
- the present invention will include a surfactant or surfactant blend which is effective to maintain a stable solution.
- non-ionic, cationic, and anionic surfactants are added to the carrier for emulsification of those challenging cleaning deposits.
- the cleaning composition may include a non-ionic surfactant. Any non-ionic surfactant which can form a micro emulsion between the carrier and the organic solvent can be utilized in the present invention.
- Typical non-ionic surfactants include the polyoxyethylene glycols, such asoctaethylene glycol monododecyl ether or pentaethylene glycol monododecyl ether; polyoxypropylene glycol; glucoside alkyl ethers such as decyl glucoside, lauryl glucoside or octyl glucoside; polyoxyethylene glycol octylphenol ethers, such as TRITON X-100®; polyoxyethylene glycol alkylphenol ethers, such as nonoxynol-9; glycerol alkyl esters, such as glyceryl laurate; polyoxyethylene glycol sorbitan alkyl esters, such as polysorbate; sorbitan alkyl esters; cocamide MEA; cocamide DEA; dodecyldimethylamine oxide; block copolymers of polyethylene glycol and polypropylene glycol and polyethoxylated tallow
- non-ionic surfactants must be effective to produce microemulsions of the carrier and the organic solvent.
- suitable non-ionic surfactants also include alkoxylated alcohols and modified alkoxylated alcohols, such as DelONIC LF and DeIONICLF-EP-15from DeForest Enterprises, Inc.

- Fragrance is present at whatever amount is desired, generally from 0.001 to 1.0% by weight, and the biocide is generally present in an amount from 0.01 to 2.0%.
- Such fragrances suitable for the present invention is Mango Odorsynthesis Fragrance F- 148707 and SpearmintOdorsynthesisFragrance from Intarome Fragrance and Flavor Corp.
- the cleaning composition should have a basic pH generally in the range of 9-11 and in particular about 10.5. If necessary, a base, such as a sodium carbonate, can be added to alter the pH.
- a base such as a sodium carbonate
- the non-aqueous organic carrier and high solvency organic solvent areblended with the surfactant and the corrosion inhibitor. As this mixing continues, any other desired components, such as a chelating agent, fragrance, biocide, and finally the wetting agent are added in and mixing continued until a stable micro emulsion is formed.
- This composition due to the high solvency of the organic solvent, can be added to the induction air intake system of a gasoline engine as previously described to effectively remove buildup at the air intake valves.
- the composition may be sprayed into the air intake while the engine is running.
- the composition may be introduced into the fuel system, such as by a pressurized bottle, to clean it.
- the engine may run on the composition, burning or combusting it while the gas line/tank is disconnected.
- the composition may also be used in the fuel tank, mixed with gasoline to clean components in contact with gasoline such as the fuel injectors and combustion chamber.
- the composition may also be used in port fuel injected motors and carbureted engines.
- compositions described herein can be successfully mixed with common gasoline and hydrocarbon solvents (e.g., xylenes, toluene, etc.) to clean carbon from engine surfaces.
- the composition of the present invention can be used at any point in time during the life of the engine but typically will be utilized either after the engine has been used for a relatively long period of time, such as the time to go 100,000 miles in an automobile or truck, or when the gas mileage of an automobile or truck begins to decrease. Thus, it can be used on engines and vehicles that are experiencing reduced performance or simply periodically as preventive maintenance.
- the cleaning composition will be introduced into the intake valve through the air induction system. Additional cleaning composition can be added if the deposits on the intake valves are particularly severe or if performance issues are confirmed by a borescope or OBD scan tool.
- the rate of injection should be approximately 3 gallons per hour.
- the present invention provides cleaning compositions and methods of using the cleaning compositions to remove carbonaceous oily buildup on air intake valves of gasoline engines. This will effectively increase the life of the engine and provide improved overall performance.
- Suitable formulations containing high solvency, no fuel value solvents are listed below: Formula A Weight (%)
- the above formulation was tested on a direct injected gasoline Hyundai Sonata (2.4L GDI engine) with 23,000 miles. There were significant black deposits on the intake valves. As the car was running, the 44 oz of the above formulation was used in induction cleaning. The cleaning process resulted in cleaner intake valves.
- the above formulation was also tested on a direct injected gasoline Hyundai Sonata SE with 25,527 miles. There were significant black deposits on the fuel rails and piston tops. The cleaning process on the piston tops was after the fuel rail treatment and was conducted without induction cleaning. The cleaning process resulted in cleaner fuel rails and piston tops.
