Definitions
- This invention relates generally to friction modifiers and, more particularly, to a new fuel composition and method for reducing friction in internal combustion engines.
- PFI port-fuel injection
- GDI gasoline direct injection
- PFI and GDI engines require fuel additives to control deposits in the injectors, intake valves and combustion chamber.
- further fuel economy improvement could be achieved by reducing the friction between the cylinder liner and piston ring interface, the valve train and the fuel pump, especially in GDI engines. Therefore, there is a need in the petroleum industry to develop a fuel and fuel additive package that addresses the engine deposit and friction reduction requirements of PFI and GDI engines.
- Organic friction modifiers are compounds that can affect the boundary layer conditions experienced by the cylinder liner and piston ring interface under these severe engine operating conditions. These types of friction modifiers are surface active and produce a protective coating on the metal surface of the engine by forming a monolayer through the interaction of the metal surface with the polar end of the friction modifier. Subsequent layers of the friction modifier can then build up to provide friction reduction in the boundary layer and help to prevent the two surfaces and their asperities from contacting each other.
- the challenge in overcoming the frictional design limitations lies in identifying a friction modifier which can influence the boundary layer properties without leading to undesirable effects, such as intake valve deposits and oil thickening.
- Friction modifier additives and detergents commonly added to combustible fuels are generally higher molecular weight compounds that may not be completely burned during the combustion process within spark ignition engines.
- some of the additive interacts with the lubricant oil film present in the combustion cylinder. This interaction allows some of the additive to become mixed with the lubricant.
- the lubricant oil film is replenished, it becomes mixed with fresh lubricant from the main lubricant reservoir and some of the absorbed additive migrates past the piston rings and into the oil pan. As a result, there is a slow transfer of additive from the fuel to the lubricant.
- the amount of additive that is transferred from the fuel to the lubricant can be as high as about 30%. Based on typical friction modifier additive concentrations expected for gasoline, this level of transfer may lead to friction modifier concentrations in the lubricant of up to about 0.5 wt % over a 5,000 mile lube drain interval. Therefore, the addition of an organic friction modifier to a combustible fuel can impact the cylinder liner and piston ring frictional interaction directly within the combustion chamber and can also accumulate in a lubricant to improve the frictional properties in other parts of the engine drive train contacted by the motor oil (e.g., valve train, cam shaft, bearings, etc.).
- the motor oil e.g., valve train, cam shaft, bearings, etc.
- a new fuel composition which contains a combustible fuel, a detergent package and a friction modifier that has a strong affinity for metal surfaces, but not so strong as to leave deposits. It would also be desirable to provide a method for reducing the amount of friction in an internal combustion engine by adding the new fuel composition to the engine to positively impact the friction of the cylinder liner and piston ring interface and the drive train of the engine, and lead to lower emissions, higher fuel economy and increased net horsepower.
- the fuel composition comprises a combustible fuel, an effective friction reducing amount of at least one C 6 to C 30 aliphatic amine, and a detergent package.
- the invention provides a fuel additive composition comprising an effective friction reducing amount of at least one C 6 to C 30 aliphatic amine and a detergent package.
- the invention also provides a method of reducing the amount of friction in an internal combustion engine comprising the step of adding to the engine a fuel composition comprising a combustible fuel, an effective friction reducing amount of at least one C 6 to C 30 aliphatic amine, and a detergent package.
- the inventive method effectively reduces the amount of friction in an internal combustion engine by adding the fuel composition of the present invention to the engine, thus leading to lower emissions, higher fuel economy, and increased net horsepower.
- the present invention is directed to a new fuel composition and method for reducing the amount of friction in an internal combustion engine.
- the fuel composition comprises a combustible fuel, an effective friction reducing amount of at least one C 6 to C 30 aliphatic amine, and a detergent package.
- the fuel composition is added to the internal combustion engine to effectively reduce the amount of friction in the engine.
- the combustible fuels which may be used include gasoline and diesel fuel, with the preferred fuel being gasoline.
- Gasoline comprises blends of C 4 -C 12 hydrocarbons which boil in the range of 25° C. to 225° C., and satisfy international gasoline specifications, such as ASTM D-4814 and EN228. These gasoline blends typically contain mixtures of normal and branched paraffins, olefins, aromatics and naphthenic hydrocarbons, and other liquid hydrocarbon containing components suitable for spark ignition gasoline engines, such as conventional alcohols and ethers.
- the gasoline can be derived from petroleum crude oil by conventional refining and blending processes, such as straight run distillation, hydrocracking, fluid catalytic cracking, thermal cracking, and various reforming technologies.
- the C 6 to C 30 aliphatic amines which may be used as friction modifiers in the practice of the invention include saturated fatty acid amines, unsaturated fatty acid amines, and mixtures thereof.
- Preferable C 6 to C 30 aliphatic amines include, but are not limited to, octyl-, decyl-, dodecyl-, tetradecyl-, hexadecyl-, hexadecenyl-, octadecyl-, octadecenyl-amines, and mixtures thereof.
- Tallow amines are particularly preferred C 6 to C 30 aliphatic amines, with hydrogenated tallow amines being most preferred.
- An example of a suitable hydrogenated tallow amine is Armeen®HTD, available from Akzo Nobel Surface Chemistry LLC.
- the fuel composition preferably contains an effective friction reducing amount of the C 6 to C 30 aliphatic amine in the range of from about 1 ppm to about 2000 ppm (parts per million). More preferably, the amount of the C 6 to C 30 aliphatic amine present in the fuel composition is in the range of from about 5 ppm to about 1000 ppm, with about 10 ppm to about 500 ppm being most preferred.
- the detergent packages which may be used in the practice of the present invention are well known to those skilled in the art and commercially available. Suitable commercial detergent packages include, but are not limited to, Keropur® and Kerocom® packages available from BASF A.G., HiTEC® packages available from Afton Chemical Corporation, and OGA® packages available from Chevron Oronite Company LLC.
- the detergent packages typically include at least one deposit control additive, a corrosion inhibitor, a carrier fluid, and a solvent.
- Some commercially available detergent packages do not contain a corrosion inhibitor and may be used in the practice of the present invention, however, it is preferred that a corrosion inhibitor be included.
- the appropriate amount of each component in the detergent package will vary depending upon the specific engine performance benefit being sought and can be readily determined by those skilled in the art.
- the detergent package typically contains at least one high molecular weight nitrogen-containing deposit control additive.
- deposit control additives include polyalkylene amines, polyalkylene succinimides, Mannich bases, and polyether amines.
- the preferred deposit control additive for use in the present invention is a polyisobutylene (FIB) amine. Examples of suitable PIB-amines are taught in U.S. Pat. No. 4,832,702, the disclosure of which is incorporated herein by reference.
- the corrosion inhibitors which may be utilized in the practice of the present invention include, but are not limited to, monomers, dimers, and trimers of long chain organic acids, and various esters, imides, thiadiazoles, and triazoles.
- the carrier fluids which may be used in the detergent package are preferably compatible with the combustible fuel and have the ability to dissolve or disperse the components of the detergent package.
- Examples of conventional carrier fluids include mineral oils and synthetic oils, such as poly a-olefin oligomers, polyethers, polyether amines, and carboxylic esters of long chain alkanols.
- solvents there are various alcohols and aromatic hydrocarbons which may be used as solvents in the practice of the present invention.
- suitable solvents include xylenes, toluene, tetrahydrofuran, isopropanol isobutylcarbinol, and n-butanol; and petroleum hydrocarbon solvents, such as naphtha and the like.
- the fuel composition may comprise another friction modifier in accordance with the present invention. It was discovered that when certain friction modifier combinations are utilized, greater coefficient of friction reduction is achieved than when either friction modifier is used alone. In particular, when a glycerol monoalkyl ether, more preferably, a glycerol monooleyl ether is combined with a hydrogenated tallow amine, the interaction of the two friction modifiers leads to significantly improved lubricity.
- the fuel composition preferably contains an effective friction reducing amount of the glycerol monoalkyl ether in the range of from about 1 ppm to about 1000 ppm. More preferably, the amount of the glycerol monoalkyl ether present in the fuel composition is in the range of from about 5 ppm to about 500 ppm, with about 10 ppm to about 250 ppm being most preferred.
- the fuel composition may be added to an internal combustion engine by any conventional method and can be used in internal combustion engines that burn liquid fuel, especially spark-ignited gasoline engines encompassing carbureted, PFI and GDI, as well as in vehicles containing compression-ignited engines, such as diesel engines.
- internal combustion engines that burn liquid fuel
- spark-ignited gasoline engines encompassing carbureted, PFI and GDI
- vehicles containing compression-ignited engines such as diesel engines.
- a fuel additive composition containing an effective friction reducing amount of at least one C 6 to C 30 aliphatic amine and a detergent package is provided. All of the suitable components which may be used in the fuel additive composition and their respective amounts are the same as those described above with respect to the fuel composition.
- the fuel additive may be combined with a combustible fuel in any conventional manner generally known to those having ordinary skill in the art to which this invention pertains and then added to an internal combustion engine to effectively reduce the amount of friction in the engine.
- SRV® instrument was utilized to determine the performance of a number of friction modifier additives.
- the SRV instrument measures the coefficient of friction and wear scar of a lubricant resulting from the oscillation of a ball on a disc at a constant set of conditions.
- SRV reciprocation tests were done using a commercial Castrol GTX® 5W30 (GF-4) motor oil that was spiked with various commercially available organic friction modifier additives.
- the organic friction modifier additives tested were glycerol monooleate (GMO), which was obtained from Oronite Chemical Company, oleylamide (Crodamide® O), obtained from Croda Chemicals, glycerol monooleyl ether (FM-618C), obtained from Adeka USA, and hydrogenated tallow amine (Armeen HTD), obtained from Akzo Nobel Surface Chemistry LLC. Test samples were prepared by mixing 0.5 grams of the organic friction modifier with 99.5 grams of the Castrol GTX 5W30 motor oil.
- GMO glycerol monooleate
- Crodamide® O oleylamide
- FM-618C glycerol monooleyl ether
- Armeen HTD hydrogenated tallow amine
- the SRV instrument uses a steel ball as the upper test piece and a steel disk as the lower test piece. An oil sample was placed on the disk, a load was applied to the ball from the top, and the ball was vibrated parallel to the disk as the ball was pressed against the disk. The lateral load applied to the disk was measured to calculate the coefficient of friction. The coefficient of friction was taken as the average of the data for a particular temperature.
- the SRV test conditions were 50 N load, 50 Hz oscillation, 1 mm stroke and 1 hour duration. The initial temperature was set to 80° C. for the first 30 minutes of testing and then rapidly raised to 120° C. for the final 30 minutes. This procedure provided some indication of the temperature dependence of the additive's effect on friction reduction at temperatures expected to be encountered between the cylinder liner and piston ring. The results of the testing are shown below in Table 1.
- Table 1 illustrate the superior performance of the Armeen HTD (hydrogenated tallow amine) relative to other known friction modifier additives. These data show that at 120° C., the coefficient of friction can be lowered by approximately 16% relative to that of a commercial Castrol GTX motor oil meeting the GF-4 specifications through the use of the Armeen HTD additive. The coefficient of friction values are significantly tower than those of the GMO additive (at both temperatures) and show improvement over the high temperature data for the Crodamide O additive. Both the GMO and Crodamide O additives are well-known friction modifier chemistries and have been used extensively in motor vehicle lubricants.
- the inventive composition and method can effectively reduce the amount of friction within an internal combustion engine (in particular, the cylinder liner and piston ring interface and the drive train) by producing improved lubricity.
- the lower friction in turn can lead to lower emissions, higher fuel economy, and an increase in net horsepower.
- Intake valve deposit measurements were carried out on a Ford 2.3 L engine dynamometer Intake Valve Deposit (IVD) clean-up test stand according to a modified version of the standard ASTM D6201 procedure. Clean valves were installed in the engine and then a retail gasoline which contained the minimum amount of detergent additive as required by the US EPA (i.e., the lowest additive concentration or LAC) was run for 50 hours following a Coordinating Research Council (CRC) drive cycle. The engine was disassembled, the valve weights were measured, and then reassembled to determine the clean-up performance of the test fuels using a 100 hour test following the CRC drive cycle.
- the IVD clean-up performance results of a comparative detergent package (345 ppmv) containing a PIB-amine, corrosion inhibitor, carrier fluid, solvent and dye, and the detergent package in combination with the Armeen HTD additive are shown below in Table 2.
- Example 1 The same SRV testing of the friction modifier additized Castrol GTX 5W30 motor oil performed above in Example 1 was conducted in this example to determine the performance of a combination of additives, namely FM-618C and Armeen HTD. Additional test samples were prepared by mixing 0.2 grams of the organic friction modifier with 99.8 grams of the Castrol GTX 5W30 motor oil. All of the coefficient of friction results from Example 1 and from the testing in this example of the combination of the FM-618C and Armeen HTD friction modifier additives are shown below in Table 3.
- the inventive composition and method improves lubricity and helps reduce the amount of friction within an internal combustion engine through the synergistic interactions of two different friction modifier chemistries added via the fuel.
- This synergistic behavior effectively lowers the amount of friction within the cylinder liner and piston ring interface and the drive train of the internal combustion engine.
- the lower friction in turn can lead to lower emissions, higher fuel economy, and an increase in net horsepower.
