## Abstract

A method for enriching air with hydrogen for subsequent use by internal combustion engines is discussed. The method begins with supplying a modified form of water. Subsequently, the method continues with electrolyzing the water to produce hydrogen gas. Next, the method involves mixing the gas with air to produce a hydrogen-air mixture, and injecting the mixture into the air intake of a combustion engine. Also discussed is a system for enriching internal combustion engine air intake with hydrogen gas. The system uses modified water, an electrolysis unit for producing hydrogen gas from the modified water. The system mixes the gas with ambient air to create a mixture, and a venturi-based injector introduces the mixture into the air intake system of the engine.

## Claims

### Claim 1

A method for enriching air with hydrogen for subsequent use in internal combustion engines, the method comprising:
a. without preheating, supplying a modified form of water, wherein the modified form of water comprises alcohol and alkali-metal containing moiety;
b. electrolyzing the water to produce hydrogen gas while the modified water remains in a liquid phase;
c. mixing the hydrogen gas with air to produce a hydrogen-air mixture; and
d. injecting the mixture into the air intake of a combustion engine, wherein said alcohol comprises medical grade alcohol having purity of at least 95 percent by weight; wherein 2% to 2.8% of the modified water comprises sodium hydroxide as the alkali-metal moiety and wherein 27% to 30% of the modified water comprises 2-propanol and wherein said water base comprises deionized water.

### Claim 2 (depends on 1)

The method of claim 1 wherein the alkali-metal containing moieties are selected from the group consisting of potassium hydrogen sulfite (KHSO3), sodium hydrogen sulfite (NaHSO3) and combinations thereof.

### Claim 3 (depends on 1)

The method of claim 1 further producing oxygen.

### Claim 4 (depends on 1)

The method of claim 1 wherein the step of electrolyzing the water comprises contacting the modified form of water to a plurality of parallel flat plates maintained at a voltage potential, the plurality enclosed in a leak proof bladder and wherein the plurality of plates has a first end terminating in a positive electrode and a second end terminating in a negative electrode and the edges of the plates deviate from the plane and toward the negative electrode.

### Claim 5 (depends on 1)

The method of claim 1 wherein the hydrogen-air mixture comprises between 1 to 5 volume percent of hydrogen gas to air.

### Claim 6 (depends on 1)

The method of claim 1 wherein the mixture is not preheated prior to injection.

### Claim 7 (depends on 1)

The method of claim 1 wherein the electrolyzing step occurs at temperatures as low as −50 F without the addition of heat.

### Claim 8 (depends on 1)

The method of claim 1 wherein the step of electrolyzing water produces a mixture of hydrogen gas and the modified form of water, the method further comprising separating the hydrogen gas from the modified form of water to provide hydrogen gas and separated water and returning the separated modified form of water to the source of modified water for continued processing.

### Claim 9

A system for enriching internal combustion engine air intake with hydrogen gas, the system comprising:
a. a non-preheated, modified water, wherein the modified form of water comprises alcohol and alkali-metal containing moeity;
b. a means for producing hydrogen gas from the modified water while the modified water remains in a liquid phase;
c. a means for mixing the hydrogen gas with air to create a gas mixture; and
d. a means for injecting the mixture into the air intake system of the engine wherein said alcohol comprises medical grade alcohol having purity of at least 95 percent by weight; wherein 2% to 2.8% of the modified water comprises sodium hydroxide as the alkali-metal moiety and wherein 27% to 30% of the modified water comprises 2-propanol and wherein said water base comprises deionized water.

### Claim 10 (depends on 9)

The system of claim 9 wherein the alkali containing moieties are selected from the group consisting of KOH, NaOH and combinations thereof.

### Claim 11 (depends on 9)

The system of claim 9 wherein the alkali containing moieties are selected from the group consisting of Potassium Carbonate (K2CO3), Sodium Carbonate (NaCO3), Potassium Hydrogen Carbonate (KHCO3), Sodium Hydrogen Carbonate (NaHCO3) and combinations thereof.

### Claim 12 (depends on 9)

The system of claim 9 wherein the alkali containing moieties are sulfates selected from the group consisting of potassium sulfate, sodium sulfate, and combinations thereof.

### Claim 13 (depends on 9)

The system of claim 9 wherein the medical grade alcohol of the modified water is a medical grade isopropyl alcohol.
