L THOMAS MIDGLEY, JR., DAYTON, OHIO, ASSIGNOR, BY MESNR ASSIGNMENTS, TO
GENERAL MOTORS CORPORATION, OF DELAWARE.
DETROIT, MICHIGAN, A CORPORATION 01? METHOD AND MEANS FOR USING LOW -COMPRESSI ON FUELS.
No Drawing.
To all whom it may concern:
Be it known that I, THOMAS MIDGLEY, J r., a citizen of the United States of America, residing at. Dayton, county of Montgomery, and State of Ohio, have invented certain new and useful Improvements in Methods and Means for Using Low-Compression Fuels, of which the following is a full, clear, and exact description.
This invention relates to the art of suppressing a fuel knock when a combustible gaseous mixture containing a low compression fuel, such, for example, as kerosene and gasoline is burned under a relatively high pressure. Theprincipal object of this in vention is to employ arsenic compounds to suppress the fuel knock.
This application is a continuation in part )f my copending application, Serial No. 533,- 270, filed April 15, 1922.
Kerosene has a critical compression pressure of about pounds. The critical compression pressure of gasoline varies from about pounds for the commoner forms now marketed to about 125 pounds for avia tion gasoline employed in airplane engines. These fuels are termed low compression fuels. When the vapors of any one of them is mixed with air, compressed to a compression pressure in excess of the normal critical compression pressure of the fuel, and burned, as in an internal-combustion engine, a fuel knock is produced.
I have found that vapors of arsenic compounds added to the fnel-air mixture suppress this fuel knock and permit'an increase in the engine compression pressure with a normal burning characteristic of the fuel.
By way of an example of one method of carrying out my invention, I dissolve 260 c. c. of triethyl arsine as(C H in 1 gallon of gasoline, having a normal critical compression pressureof about 75 pounds. This solution or high compression fuel is fed through a carburetor into the cylinder of Application filed September 18, 1923. Serial No. 663,496.
an internal-combustion engine having a compression pressure of about pounds, the solution being vaporized and mixed. with a r as is common practice in engine operation. The gaseous high compression fuel is ignited and the engine operated without a fuel knock. The gasoline forms the fuel base and the arsenic compound increases the critical compression ressure of this base.
This process may e vareid by changing the proportions according to the increase in critical compression pressure desired and by using other arsenic compounds in place of the diethyl arsine. Among the compounds which may be substituted for diethyl arsine are other alkyl compounds including trimethyl arsine, and triphenyl arsine.
I prefer to employ the arsenic compounds which are soluble in the fuel to promote the mixing of the two. Blending agents may be employed if the arsenic compound does not-dissolve readily in the fuel. The
compound may be added to the fuel-air mixture just before the latter is burned.
I claim:
a 1. A composition of matter comprising a low compression fuel; and a volatile arsenic compound incorporated therein and adapted to increase the critical compression pressure of the fuel.
2. A composition of matter comprising a low compression fuel,' such as kerosene or gasoline; and a volatile alkyl compound of arsenic incorporated homogeneously therein and adapted to increase the critical compression pressure of the fuel.
3. A composition of matter comprising a low. compression fuel; and a volatile ethyl compound of arsenic incorporated therein.
4. A composition of matter comprising gasoline; and triethyl arsine.
In testimony whereof I hereto aflix my signature.
