Definitions

  • water can be used to improve the combustion of liquid hydrocarbon fuels used in internal combustion machines. Water being introduced into the combustion chamber either together with the fuel in the form of an emulsion (most common) or by injection into the combustion air stream (least common).
  • Crankcase lubricating oils intended for use in internal combustion machines are dosed at 20:1 to 2,000: 1 with a micro-emulsion forming additive.
  • the resulting lubricating oil composition is hoped to improve engine fuel efficiency to such an extent that the invention can be employed in a significantly cost effective manner not previously realized by any prior art lubricating oil emulsion.
  • Another desire is to increase engine power.
  • Additive compositions which can be mixed with engine crankcase lubricating oils to form stable "water-in-oil" micro-emulsions.
  • Improved combustion and fuel efficiency can be achieved by dosing the additive into lubricating oils using a dose ratio of from about 20: 1 up to about 2,000: 1 (preferably from about 100:1 up to about 400: 1).
  • the first way is from the cylinder walls past the piston rings.
  • the second way is down the intake valve stem (where it is picked up by the incoming gasoline/air mixture and thereby carried into the engine combustion chamber).
  • the additives are produced by mixing together appropriate proportions of surfactant(s), co-surfactant(s) and water. Hydrocarbon solvents can also be included.
  • each droplet having an initial diameter from about 1.0 to 100 nanometers (0.001 to 0.1 microns), typically 3.0 to 9.0 nanometers.
  • These dispersed micro-emulsified water droplets remain in stable suspension until such time as they are carried into the combustion chamber with the oil.
  • Additives of the present invention can be produced which are stable enough for most commercial applications. These severe "real world” applications require emulsion stability from below - 40 deg C to over +80 deg C, not only as an additive but also after dosing into the oil.
  • glycols Although specific glycols have been named as being suitable co-surfactants, other low molecular weight glycols (either alone or in combination) could also be used.
  • glycol ethers have been employed in combination with low molecular weight alcohols to form strong coupling agents well known to those skilled in the art.
  • these glycol ethers can be obtained from Dow Chemical under the trade names Dowanol DPM (dipropylene glycol methyl ether) and Dowanol EB (ethylene glycol n-butyl ether).
  • Dowanol DPM dipropylene glycol methyl ether
  • Dowanol EB ethylene glycol n-butyl ether
  • these two glycol ethers have been specifically named as being suitable co-surfactants, other glycol ethers might also be suitable.
  • hydrocarbon (HC) solvent when making certain of the additives, those skilled in the art will realize that other hydrocarbon solvents (including oxygenated hydrocarbons) could easily be used instead of kerosene.
  • hydrocarbon solvents including oxygenated hydrocarbons
  • aliphatic, aromatic or paraffinic hydrocarbons either alone or in
  • the co-surfactant(s) was either the next or the first ingredient.
  • Some may have better high (or low) temperature stability, or have improved pour point, flash point, cost, viscosity, corrosiveness, commercial availability, toxicity, freezing point, color, smell, legislative acceptability, or any number of other particular benefits depending on the balance of importance prevailing at the time.
  • Examples #1 to #12 require surfactant to water ratios of typically 7: 1 in order to produce sufficiently stable emulsions. However, when using these more "sophisticated" surfactant packages, this ratio could be reduced to 3: 1 or less (sometimes much less).
  • Co-surfactant(s) 350 to 2,200 0 to 13,750
  • Concentrated micro-emulsion oil additive #13 was then added to the engine oil used in this vehicle at a dose ratio of 200: 1 (25ml per 5 liters) and the vehicle was driven for 2 weeks using a typical daily commuter driving pattern. During this time, the driver reported a noticeable increase in engine power.
  • This same Lexus LS400 vehicle (which normally required the use of 92 octane fuels) could then use regular 87 octane fuels with no noticeable loss of power, knocking, pinging, or driveability problems.
  • Mileage testing on this same vehicle showed about a 10% improvement (from 19.0 mpg to 20.9 mpg), even when using the 87 octane fuel instead of 92 octane fuel.
  • Concentrated micro-emulsion oil additive #13 was then added to the engine oil used in this vehicle at a dose ratio of 200: 1 (25ml per 5 liters) and the vehicle was driven for 2 weeks using a typical daily commuter driving pattern. During this time, the driver reported a noticeable increase in engine power.
  • the exhaust smoke level was measured by the "snap-idle" test using a N.T.K. model ST- 100 diesel emission smoke tester (manufactured by Komyo Rikagku Kogyo K.K. of Japan). Opacity levels reduced from 14.8% down to 12.6%, or about a 15% reduction (average of 6 tests). Mileage testing on this same vehicle showed about a 6% improvement (from 34.0 mpg to 36.0 mpg) when using #13 oil additive.
  • Concentrated micro-emulsion oil additive #13 was then added to the engine oil used in this vehicle at a dose ratio of 100: 1 (40ml per 4 liters) and the vehicle was driven for 2 weeks using a typical daily commuter driving pattern. During this time, the driver reported a noticeable increase in engine power.
  • Mileage testing on this same vehicle showed about a 10% improvement (from 21.0 mpg to 23.3 mpg).
  • Concentrated micro-emulsion oil additive #13 was then added to the engine oil used in this vehicle at a dose ratio of 200:1 (75ml per 15 liters) and the vehicle was driven for 2 weeks using a typical daily commuter driving pattern. During this time, the driver reported a noticeable increase in engine power.
  • the exhaust smoke level was measured by the "snap-idle" test using a N.T.K. model ST- 100 diesel emission smoke tester (manufactured by Komyo Rikagku Kogyo K.K. of Japan). Opacity levels reduced from 14.8% down to 12.6%, or about a 15% reduction (average of 6 tests).
  • Mileage testing on this same vehicle showed about a 6% improvement (from 16.6 mpg up to 17.6 mpg) when using #13 oil additive.
  • Concentrated micro-emulsion oil additive #13 was then added to the engine oil used in this vehicle at a dose ratio of 400: 1 (12.5ml per 5 liters) and the vehicle was driven for 2 weeks using a typical daily commuter driving pattern. During this time, the driver reported a noticeable increase in engine power. Mileage testing on this same vehicle showed about a 10% improvement (from 16.8 mpg to 18.5 mpg).
  • test #1 The same vehicle used for test #1 (the 1990 Lexus LS400), was also used for test #6. Immediately after the completion of test #1, the treated oil was drained and the engine refilled with fresh oil (this time containing no oil additive). However, it is impossible to fully drain 100% of the oil from the engine in the 1 or 2 minutes taken for a typical oil change. Consequently, about 10% of the original oil (treated with the oil additive) still remained in the engine.
  • Lexus LS400 vehicle (which normally required the use of 92 octane fuels) could use 89 octane fuels with no noticeable loss of power, knocking, pinging, or driveability problems.
  • test #6 The same vehicle used for test #6 (the 1990 Lexus LS400), was also used for test #7. Immediately after the completion of test #6, the oil was drained and concentrated micro-emulsion oil additive #13 was added to the fresh engine oil used in this vehicle at a dose ratio of 20: 1 (250ml per 5 liters) and the vehicle was driven for another 2 weeks using the same typical daily commuter driving pattern. During this time, the driver reported slightly more increase in engine power than was achieved with test #1.
