Abstract
Abstract A device and method for improving the combustion characteristics of liquid fuels is shown. The device has an elongated casing with a hollow interior and inlet and outlet ports which are inserted in the fuel line of the fuel to be treated. An elongated metal bar is placed within the casing so that the exterior surfaces of the bar contact the fuel flowing within the casing. The metal bar is an alloy made of nickel, zinc, copper, tin, and silver which is generally triangular in cross-sectional area and substantially occupies the interior of the casing. Spaced-apart elevated ridges in the exterior surfaces of the metal bar promote turbulent flow in the fuel passing through the casing and over the surfaces of the metal bar.

Claim 2
Dependent Claim
49 words
A fuel treating device for improving the combustion characteristics of liquid fuels comprising: a casing through which liquid fuel is adapted to flow; an elongated metal bar located inside said casing for contacting said fuel flow; said metal bar comprising an alloy of nickel, zinc, copper, tin, and silver.
Claim 3
Dependent Claim
18 words
The device of claim 1, wherein said elongated metal bar has a platinum coating on either end thereof.
Claim 4
Dependent Claim
109 words
A fuel treating device for improving the combustion characteristics of liquid fuels, comprising: an elongated casing having a hollow interior and inlet and outlet ports for receiving and discharging fuel; an elongated metal bar of generally triangular cross-sectional area located within and substantially occupying the hollow interior of said casing, said elongated bar having exterior surfaces in contact with said fuel being received and discharged through said casing ports; the exterior surfaces of said elongated bar in contact with said fuel having spaced-apart elevated ridges for promoting turbulence in said fuel flowing through said casing; said elongated metal bar comprising an alloy of nickel, zinc, copper, tin, and silver.
Claim 5
Dependent Claim
109 words
A fuel treating device for improving the combustion characteristics of liquid fuels, comprising: an elongated casing having a hollow interior and inlet and outlet ports for receiving and discharging fuel; an elongated metal bar of generally triangular cross-sectional area located within and substantially occupying the hollow interior of said casing, said elongated bar having exterior surfaces in contact with said fuel being received and discharged through said casing ports; the exterior surfaces of said elongated bar in contact with said fuel having spaced-apart elevated ridges for promoting turbulence in said fuel flowing through said casing; said elongated metal bar comprising an alloy of nickel, zinc, copper, tin, and silver.
Claim 6
Dependent Claim
17 words
The device of claim 3, wherein said metal bar has a platinum coating on either end thereof.
Claim 7
Dependent Claim
42 words
The device of claim 4, wherein said alloy comprises 10-30 weight percent nickel, 15-40 weight percent zinc, 30-60 weight percent copper, 5-20 weight percent tin, and 1-10 weight percent silver, the weight percentages being based on the total weight of alloy present.
