Abstract

Abstract Fuel for an internal combustion engine is treated by flowing the fuel into intimate contact with a crystalline metal alloy that includes copper, zinc, nickel, lead, tin, iron, antimony sulfur, and manganese all in a specific range of percentage composition. The fuel can be any hydrocarbon including diesel, regular gasoline, low lead gasoline, aviation fuel, propane and butane. The crystalline metal is essentially non-sacrificial and will last hundreds of thousands of miles under ordinary conditions of usage. The crystalline metal alloy is contained within a housing through which fuel flows, whereby the fuel is placed in intimate contact with the surface area of the crystalline metal alloy, causing significant reduced pollution and increased mileage.
