Definitions

  • coal it would, of course, be highly desirable to utilize coal as a fuel for powering automobiles and other vehicles.
  • One method suggested for utilizing coal as a fuel for internal combustion engines involves converting the coal to methanol.
  • a suggested use for methanol is to add it to gasoline to make a fuel similar to gasohol.
  • methanol could fulfill a function similar to that of ethanol; but, adding methanol to gasoline presents problems. If even a small quantity of water gets into an automobile tank, a methanol-gasoline blend will separate. The methanol and water fall to the bottom of the tank, get into the engine and stall it.
  • an object of the present invention is to provide a methanol or ethanol (and other lower alcohols) based fuel which can be utilized as a substitute in whole or in part for gasoline as a fuel for an internal combustion engine.
  • the sole figure of the drawing is a graph showing increase in miles per gallon versus percent of DTBP by volume.
  • the present invention is described in its broadest overall aspects with a more detailed description following.
  • the present invention is a fuel composition for an internal combustion engine. It includes methanol or ethanol or other lower alcohols and an additive.
  • the fuel composition may be utilized directly as a fuel for a typical gasoline engine or it may be mixed with gasoline in any proportion for use in such engines.
  • the additive itself is an alkyl peroxide.
  • the preferred alkyl peroxide is a ditertiary alkyl peroxide of the general formula: where R 1 through R 6 are lower alkyl radicals.
  • the most preferred additive is di-t-butyl peroxide of the formula:
  • Tertiary alkyl hydroperoxides having the following formula may also be used: where R l to R 3 are lower alkyl radicals.
  • the preferred alkyl hydroperoxide is t-butyl hydroperoxide of the formula:
  • Tests with methanol also indicate that the peroxide additives will improve the performance of straight ethanol and gasohol.
  • the fuel composition of the present invention is a mixture of methanol and/or ethanol and a peroxide, but may contain additives to improve the overall characteristics and performance of the fuel.
  • the fuel composition preferably contains about 1.5-6% peroxide with the balance being substantially methanol.
  • methanol As used throughout this specification and claims, all percentages are by volume at room temperature unless otherwise specified. To this composition, other additives may be added. The composition may be used straight or mixed with gasoline in any proportion. Also, all or part of the methanol may be replaced by ethanol to yield an improved fuel.
  • a di-tertiary alkyl peroxide (specifically di-tertiary butyl peroxide) and methanol was blended.
  • a mixture of 10% peroxide and 90% methanol was quite efficient but it was found that a 15%-85% mixture was a more optimum ratio.
  • the viscosity of this mixture being higher than gasoline, necessitated a change in the size of the Lincoln carburetor jets from 61 thousandths to 69 thousandths. With this size jet the peroxide mixture flows freely through the carburetor. This was the only modification made on the Lincoln for all experiments.
  • Experiment #5 Ran 4 3/4 oz. of #2 mixture and 1/4 oz. water. Speed 2,000 rpm, Brake 3 lbs., Time 18 3/4 minutes. (had to run leaner mixture with throttle adjustment)
  • Experiment #6 Ran 5 oz. methanol with throttle adjustment of #5. Speed 2,600 rpm, Brake 3 lbs., Time 10 3/4 minutes.
  • Experiment #13 Ran 5 oz. methanol, open throttle to almost maximum to obtain nearly same speed with greater brake pressure. Speed 3,000 rpm, Brake 7 1/2 lbs., Time 5 minutes.
