Abstract

Abstract A gas-operated combustion engine for driving a vehicle, the vehicle carrying a hydrogen gas generator including a magnesium electrode immersed in a salt-water electrolyte. The rate of gas evolution in the generator is controlled as a function of demand, the gas being intermixed with air and supplied to the cylinders of the engine.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 149 words
A GAS-OPERATED INTERNAL-COMBUSTION ENGINE ADAPTED TO DRIVE A VEHICLE AND HAVING A CARBURETOR, COMPRISING: A. A GAS GENERATOR MOUNTED ON SAID VVEHICLE, SAID GENERATOR INCLUDING A TANK HAVING A SALT-WATER ELECTROLYTE AND A MAGNESIUM ELECTRODE SUSPENDED IN SAID ELECTROLYTE TO CAUSE HYDROGEN TO EVOLVE IN THE TANK, B. ADJUSTABLE MEANS COUPLED TO SAID GENERATOR TO VARY THE RATE AT WHICH HYDROGEN IS EVOLVED IN SAID TANK. C. MEANS TO FEED HYDROGEN FROM SAID TANK INTO SAID CARBURETOR TO INTERMIX WITH AIR TO PRODUCE A COMBUSTIBLE MIXTURE, D. MEANS TO SUPPLY SAID MIXTURE TO THE CYLINDERS OF SAID ENGINE, E. MEANS TO SENSE THE AMOUNT OF HYDROGEN CONSUMED BY THE ENGINE TO PROUCE A CONTROL SIGNAL AS A FUNCTION THEREOF, AND F. MEANS RESPONSIVE TO SAID CONTROL SIGNAL TO OPERATE SAID ADJUSTABLE MEANS WHEREBY THE AMOUNT OF HYDROGEN EVOLVED IS NOT SUBSTANTIALLY IN EXCESS OF THAT REQUIRED BY THE ENGINE.
Claim 2
Dependent Claim 149 words

Claim 3
Dependent Claim 43 words
An engine as set forth in claim 1, wherein said tank also has a carbon electrode immersed in the water, and said means to vary the rate at which hydrogen is evolved comprises a variable resistance connected between the magnesium and carbon electrodes.
Claim 4
Dependent Claim 31 words
An engine as set forth in claim 1, further including a reserve gas tank coupled to the outlet of the gas generator to accumulate a supply of hydrogen for starting purposes.
Claim 5
Dependent Claim 31 words
An engine as set forth in claim 1, further including a valve interposed between the generator and carburetor, and means operatively coupling the valve to the accelerator pedal of the vehicle.
Claim 6
Dependent Claim 15 words
