FUEL FOR INTERNAL-COMBUSTION ENGINES.

No Drawing.

To all whom it may concern:

Be it known that I, JEAN F. P. DE LA RIBOISIERE, a citizen of the French Republic, residing at Washington, D. C., U. S. A.,

have invented certain new and useful Improvements in Fuel for Internal-Combustion Engines, of whichthe following is a specification.

This invention relates to improvements in fuels ,for internal combustion engines, of the character disclosed in my application for Patent Serial No. 664586, filed September 24, 1923, of which the present applicati on is a continuation in part. In said application I have described an engine fuel including liquid hydrocarbons boiling above 160 (3., combined with an ether and a phenolic body. As stated in said application I have discovered that a large proportion of liquid hydrocarbons boiling above 160 C. may be utilized in low boiling point fuels, such as benzo-l, benzine or gasoline, providing the liquid hydrocarbons boiling above 160 C. are combined with an ether to promote the combustion or ignition of the mixture, and a phenolic body to retain the ether in the mixture.

The primary object of the present inven tion is to improve fuels of this type by employing a body containing a phenyl radical,

Among the compounds that I have found satisfactory are the phenyl compounds of selenium, tellurium, thorium, thallium, uranium, tungsten, titanium, bismuth, va-

These metallic phenyl compounds may be used but, of course, my invention is not limited to the use of these specific metallic phenyl compounds, as others may be used. While I prefer to use metallic phenyl compounds because they are more stable. my invention is not limited thereto. Other compounds containing the phenyl radical may be used in connection with the other ingredients of my fuel composition. For example, di-

benzyl salicylate, the benzyl amines, the benzyl anilines, the benzyl -alcohols and their derivatives may be used. The benzylhydroxy amines may also be used.

I have found from actual practice, that a mixture of this character will increase the speed of many types of motor vehicles at least 20 percent when climbing a steep hill. A demonstration in connection with a num- Application filed November 18., 1924. Serial No. 750,657.

ber of different types of motor cars shows an increase of speed in climbing a steep hill ot from 20 to 30 percent. As a matter of fact, in using fuel of this character, it has been demonstrated that the present mixture will increase the power of the motor at least 25 percent, and effect an economy in the consumption of fuel of about 30 percent over a similar demonstration with ordinary gasoline.

In practical use it has been found thatphenyl compounds, when radio active, have a very great influence on the power efficiency of the motor. 7

As examples of fuel mixtures which I have found to give very good results, I state as follows:

Per cent. 1. Low boiling point hydrocarbons (such as gasoline or benzol) 68 High boiling point hydrocarbons (such as heavy gas oil) 3O Ether A 1.5 Phenyl compound, forexample diphenyl telluride 0.5 2. Low boiling point hydrocarbons 58 High boiling point hydrocarbons (such as kerosene) 37 Ether.- 2.5 Phenyl compound, for example diphenyl telluride 2.5 3. Low boiling point hydrocarbons (including benzol) 30 High boiling point hydrocarbons 40 Alcohol.- 27 Ether 1.5 Phenyl com ound, for example diphenyl te luride 1.5

4. Low boiling'point hydrocarbons 30 High boiling point hydrocarbons (such as kerosene) 57 Ether 3 Phenyl compounds 10 5. Low boiling point hydrocarbons (such as gasoline or benzol) 68 High boiling point hydrocarbons (such as gas oil) 30 Ether 1.6 Dibenzyl diselenide .4

6. Low boiling point hydrocarbons 60 High boiling point hydrocarbons (such as kerosene) 37 Ether -4 2.5 Triphenyl of thallium 1 Per cent. 7.

Low boiling point hydrocarbons 60 High boiling point hydrocarbons 15 such as kerosene)' 32 Et er 1 Dibenzyl salicylate 7 10. Low boiling point-hydrocarbons 60 High boiling point hydrocarbons (such as kerosene) 37.5 Ether .5 Benzyl aniline 2 11. Low boiling point hydrocarbons" 60 H'gh boiling point hydrocarbons 36.5 Ether .5

Benzyl hydroxylamine 3 While I have disclosed a few preferred examples, it is obvious that these proportions may be varied to suit conditions.

What I claim and desire to secure by Letters Patent is:

1. An improved fuel for internal combustion engines including liquid hydrocarbons boiling above 160 C., and a smaller proportion of an ether and a compound containing a non-hydroxy phenyl radical.

2. An improved fuel for internal combus boiling above 160 tion engines including a proportion of liquid hydrocarbons boiling above 16O. 0., a small proportion of ether'adapted to promote the combustion or ignition thereof, and a proportion of non-hydroxy phenyl compounds.

3. An improved fuel for internal combustion engines including a considerable proportion of liquid hydrocarbons boiling above 160 C., a small proportion of an ether adapted to promote the combustion or ignition thereof, and a proportion ofmetallic phenyl compounds.

An improved fuel for internal combustion engines includin liquid hydrocarbons C5, and a smaller proportion-of an ether and radioactive metallic phenyl compounds.

5. An improved fuel for internal combustion engines including aproportion of liquid hydrocarbons boiling above 160 0., a small,

proportion .of ether adapted to promote the combustion or ignition thereof, and a proportion of radioactive metallic phenyl compounds.

6. An improved fuel for internal combustion englnes including liquid hydrocarbons boiling above 160 (1, and a smaller proportion of an ether and a phenyl compound of a metal. 4

In testimony whereof I hereunto aflix my signature.
