GASEOUS FUEL.

Ho Drawing.

of California, have invented new and'useful Improvements in Gaseous. Fuel, of which the following is a specification. I

This invention relates to a hydrocarbon fuel, and. particularly pertains to a liquid fuel for use in internal combustion engines and a method of producing the same. a

It is the principal object of the present invention to provide a liquid compound which may be satisfactorily used as a substitute for commercial gasoline in providing a fuel for explosive engines, said compound possessing all of the desirable qualities of gasoline and like mineral hydrocarbon oils, and, at the same time, being of such a character as to be independent of mineral oil shortage.

The present invention contemplates the use of a liquid fuel comprising proper'proportions of a light grade hydrocarbon oil of vegetable derivation, a solvent therefor, which, at the same time, supplies the desired oxygen ingredient to the mixture and a volatile diluting agent.

In producing a substitute for gasoline and other like hydrocarbon fuels it is desirable to provide a' gaseous fuel which does not have an excesslve water content, is non-corrosive, and practically smokeless and ordorless, while possessing a high flash point and producing at least an equivalent of power. With these requirementsin mind, a liquid fuel has been produced and is embodied in the present invention comprising a light grade hydrocarbon oil, such as oil of eucalyptus, oil of cedar and turpentine, a solvent for said hydrocarbon oil, such as ether, acetone or amyl-acetate, and a suitable explosive diluting agent, as alcohol. In carrying out this invention, it is to be borne in mind that refined chemicals are not necessary and that, in each instance, raw or low grade ingredients may be used. These ingredients may be mixed in any suitable proportion, although experiment has proven that the following proportions are approximately correct:

1 part light grade hydrocarbon oil 2 parts solvent I 3 parts diluting agent. In mixing the ingredients, the hydrocarbon oil and the solvent, such as ether, are

first mixed together. The ether will act to out the oil and disintegrate the molecules Specification of Letters Patent.

'the solvent administered last, a cloudy,

stratified liquid wouldresu-lt. When the ingredients have been properly mixed a de-- sirable combustible liquid will be produced. It is well known that the use of heavy grade vegetable hydrocarbon oils as gaseous fuel will result in an objectionable carbon deposit within the engine cylinders. It is also known that ether is objectionable for use alone, due to its prohibitive cost and its high volatile nature. These objections are, however, obviated by the combination 'of the ingredients in the fuel here described, and, in addition, new results are obtained, as, for example, the excessive carbon content of the vegetable oil combines with the oxygen content of the ether to insure that substantially .all of the carbon molecules of the gaseous fuel will be burnt at the time of the explosion. It is also possible to'produce a hydro- Patented June 2'7, 1922.

carbon fuel having a desirable high flash .point, due to the alcohol content of the mixture. It will thus be seen that by the proper mixing and proportion of ingredients forming the elements of the present invention a very desirable volatile fuel maybe produced, and, due to the fact'that this fuel may be made from low grade stock, competition may be had with commercial gasoline.

Having thus described my invention, what I claim I, and desire to secure by Letters Patent is:

1. A liquid fuel consisting of one part of a hydrocarbon vegetable oil and three parts of alcohol, and two parts of an oxygen supplying hydrocarbon compound which also acts to blend the ingredients.

2. A liquid fuel composed of turpentine,

ether andalcohol.

3. A liquid fuel consisting of one part of a hydrocarbon vegetable oil, two parts of ether'and three parts'of alcohol. In testimony whereof I have hereunto set my hand in the presence of two subscribing w tnesses.
