PHILIP I). HIIBNER, OF SEATTLE, WASHINGTON.

Application filed April 10,

To all whom it may concern:

Be it known that I, PHILIP D. HIBNER, a citizen of the United States, and resident of the city of Seattle, county of King, and State of \Vashington, have invented a new and useful Improvement in Internal-Coin bustion Engines, of which the following is a specification.

The object of my invention is to provide novel means for producing a compressed combustible gas by forcing compressed air and liquid fuel through a mixer and vaporizer and for supplying the compressed combustible gas to an internal combustion engine, means also being employed to supply compressed air to the engine for starting the same and for scavenging and cooling the engine cylinders. t

The object of my invention more particularly is to provide certain improvements incharge forming devices whereby the liq? uid fuel and air are forced through a suitable mixer andvaporizer and the resulting compressed combustible gas is forced from the mixer and vaporizer into a reservoir from which the engine is supplied; means controlled by the rise and fall in the pressure of the combustible gas being employed for closing and opening the supply of compressed air andliquid fuel to the mixer and vaporizer; and means being employed for opening to a greater or lesser degree the supply of compressed combustible fuel or compressed air or both to the engine, the cycle of operations of the engine being controlled by its own valves designed to alternately admit the compressed combustible gas and compressed air.

A practical embodiment of my invention is represented diagrammatically in the accompanying drawings.

The internal combustion engine 1 may be of the rotary type, its valve chests being denoted by 2. The air pump 3 is driven from the shaft4 of the engine and forces compressed air into the reservoir 5 through the line 6. Compressed air is supplied to the fuel reservoir 7 through the line 8 which line may have a reducing valve 9 therein.

A liquid fuel supply line 10 leads from the reservoir 7 to the mixer and vaporizer 11. A compressed air supply line 12 leads from the compressed air reservoir 5 also to the mixer and vaporizer 11. Means may be provided for heating the compressed air 7 as it leads from the reservoir 5 to the mixer Specification of Letters Patent.

and vaporizer, such means being herein denoted by a heater 13 located in the exhaust line 14 of theengine and surrounding coils in the compressed air supply line.

compressed air and liquid fuel controllingv valve 15 is located inthe supply lines 12 and 10. A compressed combustible gas supply line 16 leads from the mixer and vaporizer 1,1 to the compressed combustible gas reservoir 17, in which line is located a check Valve 18.

A branch line 19 leads from the compressed combustible gas line 16 to the controlling valve 15, whereby the valve is operated to close and open the compressed air and liquid fuel supply lines to the mixer and vaporizeras the pressure in the combustible gas reservoir rises and falls to predetermined points.

A drain line 20 leads from the bottom of the compressed combustible gas reservoir 17 to the top of the'liquid fuel reservoir 7 in which line is located a drain cocl; 21 whereby any liquid fuel which is deposited in the compressed combustible gas reservoir may be drained at suitable times into. the liquid fuel reservoir. A compressed combustible gas supply line 22 with' its branches leads to the valve chests 2 of the engine through a manually operated throttle valve 23.

A compressed air supply line 24 with its branches also leads to the valve chests 2 through the manually operated throttle valve 23. l w v A cut out valve 25 may be provided in the engine exhaust line 14 for controlling the passage of the products of combustion to the heater 18.

The mixer and vaporizer 11 may be like the one represented in my application filed January 27 1919,Serial No. 273365,anid the compressed air and liquid fuel controlling valve 15 may be like the one represented in my application filed January 18, 1919, Serial No. 271857.

The throttle valve 23. may be like the one represented in application filed January 28, 1919 Serial No. 273627, and the internal combustion engine may be like the one represented in my application filed March 11, 1919, Serial No. 281953.

The air pump may be like the one represented in my United States Letters Patent No.1242692 dated October 9, 1919.

In operation and presupposing the reservoir 5 to have a supply of compressed air and the reservoir 7 to have a supply of liquid fuel the throttle valve 23 is turned to a position which will supply compressed air only to the valve chests 2 of the engine, thereby starting the engine and the air pump. After the engine and pump have been started, the throttle valve 23 is turned into a position to supply both the compressed combustible gas and the compressed air to the said valve chests, the valves therein being operated to alternately supply the com pressed combustible gas and the compressed air to the engine, whereby the engine is cooled and scavenged after each combustion, thus reducing the temperature of the combustion chambers and by the complete elimination of the burned gases, materially increasing the efficiency of the engine.

The compressed air and liquid fuel supply controlling valve 15 is operated by a rise or fall in the pressure of the combustible gas in the reservoir 7 to close or open the compressed air and liquid fuel supply lines to the mixer and vaporizer, thus automatically maintaining the combustible gas at substanti ally a predetermined pressure.

The system as above described is very effective in the production of an Q'fliClGllt fuel and in the supercharging and scavenging of the engine, the arrangement of the parts being very simple and their operation automatic after the engine started.
