Abstract: A colloidal magnesium sol is formed in metered amounts, e.g., 2 g, 3 g or 4 g per 500 cc of kerosene, by arc sputtering magnesium metal electrodes under kerosene until predetermined lengths of electrodes are converted to sol. The unit volume of 500 cc is under the hood of a vehicle or over the gas tank in the trunk space for injection of the colloidal magnesium sol suspension into the fuel line either from the fuel tank or between the fuel tank and the carburetor of an internal combustion engine. The dosages required for gasoline powered automotive vehicles are set out in my copending application, WB-1, Ser. No. 569,320, filed Apr. 17, 1975 now U.S. Pat. No. 4,080,179. The dosages required for jet fuel powered aircraft are set out in my copending application, WB-2, Ser. No. 568,999, filed Apr. 17, 1975 now U.S. Pat. No. 4,080,178. The dosages required for diesel engines are set out in my copending application, WB-3, Ser. No. 568,998, filed Apr. 17, 1975 now U.S. Pat. No. 4,080,177.

Abstract: Dispensing means for dosing a liquid fuel tank of an internal combustion engine with a unit dosage of colloidal magnesium metal dispersed in kerosene comprising a container, cap metering valve at the container bottom and a delivery line from the outlet of the valve between the fuel pump and the carburetor or air injector.

Abstract: A colloidal magnesium suspension is prepared by grinding 400 mesh pure magnesium (99.8+%) in dry kerosene until it reaches colloidal dimensions (from about 500 to 1 millimicron) and is thereafter added in critical low concentration of 1/10 grams as substantially pure magnesium up to about 6 grams per 10 gallons of diesel fuel whereby improved burning of the diesel fuel is observed as evidenced by improvement in mileage of up to 50% for the same motor settings as compared to the diesel fuel to which the colloidal magnesium has not been added. Optimum amounts of about 1/2 to 4 grams of colloidal magnesium in 10 gallons are preferred in order to minimize air pollution, while giving maximum benefit for fuel economy.

Abstract: A colloidal magnesium suspension is prepared by grinding 400 mesh pure magnesium (99.8+%) in dry kerosene until it reaches colloidal dimensions (from about 500 to 1 millimicron) and is thereafter added in critical low concentration of 1/5 gram as substantially pure magnesium up to about 10 grams per 10 gallons of motor gasoline whereby improved burning of the gasoline is observed as evidenced by improvement in gas mileage of about 25% for the same spark and carburetor settings as compared with the gasoline to which the colloidal magnesium has not been added. Benefits are achieved with leaded as well as unleaded gasoline. Optimum amounts of about 1 - 2 grams of colloidal magnesium in 10 gallons are preferred in order to minimize air pollution, while giving maximum benefit for fuel economy.

Abstract: A colloidal magnesium suspension is prepared by grinding 400 mesh pure magnesium (99.8+%) in dry kerosene until it reaches colloidal dimensions (from about 500 to 1 millimicron) and is thereafter added in critical low concentration of at least 1 gram as substantially pure magnesium up to about 15 grams per 10 gallons of jet fuel whereby improved burning of the jet fuel is observed as evidenced by improvement in mileage of about 10 to 30% for the same jet engine setting as compared to the jet fuel to which the colloidal magnesium has not been added. Optimum amounts of about 3 to 8 grams of colloidal magnesium in 10 gallons are preferred in order to minimize air pollution while giving maximum benefit for jet fuel economy.
