## Title
Vapor pressure enhancer and method

## Abstract

The present invention relates to a device that installs in-line in the fuel supply line of a gasoline, diesel, propane, or natural gas powered vehicle. The device consists of a hollow cylinder that contains a tightly packed copper wire core. The copper wire serves as a catalyst to crack the fuel's carbon chain molecules as the fuel flows through the device. The resulting fuel contains more and shorter fuel molecules, has a higher vapor pressure and burns more efficiently in the vehicle's engine.

## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a device that installs in the fuel line of a gasoline, diesel, propane, or natural gas powered engine of a vehicle and functions to break the carbon chains of the carbon chain fuel molecules so that the resulting shorter carbon molecules have a higher vapor pressure and burn more efficiently in the engine. The device installs in a fuel supply line and consists of a hollow cylinder that contains tightly packed copper wire through which the fuel flows prior to being burned.
2. Description of the Related Art
Applicant's U.S. Pat. Nos. 5,048,499 and 5,197,446 each teach a vapor pressure enhancer and method for treating fuel. These patents teach a cylinder with a perforated core located inside the cylinder and the core having a central bore therethrough. One of these patents teaches that the core is formed of an alloy of copper, zinc, tin and nickel, and the other patent teaches a core formed of an alloy of copper, zinc, tin, nickel, and lead. In both inventions, the fuel passes through the cylinder and contacts the metallic core prior to being burned. Contact with the metallic core breaks the carbon chains of the fuel molecules so that the resulting shorter carbon molecules have a higher vapor pressure and burn more efficiently in the engine. The shortcoming of those prior inventions is that the core does not have enough surface area to contact with the fuel and the alloy does not work as well as a catalyst for breaking the carbon chains of the fuel molecules as desired. The teaching of those two prior patents is incorporated herein by reference.
The present invention addresses these shortcomings by providing a core of tightly packed copper wire. The copper wire is preferably pure copper wire, with no added metals. The increased surface area of the tightly packed copper wire core results in better contact with the fuel as it flows through the cylinder and the copper wire does a better job of breaking the carbon molecules than the alloys previously employed. The result is that the fuel burns more efficiently and the vehicle gets better gas mileage which saves fuel and money.
SUMMARY OF THE INVENTION
The present invention is a device that installs in the fuel line of a gasoline, diesel, propane, or natural gas powered engine of a vehicle and functions to break the carbon chains of the fuel molecules so that the resulting shorter carbon molecules have a higher vapor pressure and burn more efficiently in the engine. The device consists of a hollow cylinder that contains tightly packed copper wire through which the fuel flows prior to being burned. The cylinder is provided with threaded ends at both of its ends so that it can be installed in-line in a fuel line feeding to the engine of a gasoline, diesel, propane, or natural gas powered engine of a vehicle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now to the drawings, there is illustrated a vapor pressure enhancer 10 constructed in accordance with a preferred embodiment of the present invention. FIG. 1 shows the vapor pressure enhancer 10 as it would appear before being installed in-line in a fuel line that supplies fuel to the engine of a vehicle.
Referring also to FIGS. 2 and 3, the enhancer 10 includes a hollow tube or cylinder 12 that is provided with two female threaded ends 14 that are welded or otherwise secured to each of the two ends 16 of the hollow cylinder 12. The cylinder 12 and the female threaded ends 14 are all preferably constructed of steel. Inside the hollow cylinder 12, the enhancer 10 is provided with a tightly packed core 18 constructed of copper wire. The core 18 is held within the hollow cylinder 12 by the female threaded ends 14 which are nuts that have been welded onto the ends 16 of the hollow cylinder 12. The female threaded ends 14 serve to secure the core 18 within the hollow cylinder 12 and also serve as means for threadably securing the enhancer 10 in-line in a fuel supply line.
With the enhancer 10 installed in a fuel supply line, the fuel that flows through the fuel line must pass through the hollow cylinder 12 of the enhancer 10. The fuel contacts the tightly packed copper wire core 18 as it passes through the enhancer 10. The copper wire of the core 18 serves as a catalyst to break the longer chain molecules of the fuel into shorter molecules. The fuel pressure activates the copper catalyst to cause this catalytic cracking or breaking of the fuel molecules.
The large surface area of the copper wire core 18 causes better contact between the fuel and the catalyst, resulting in more fuel molecules being broken into shorter molecules. Breaking fuel molecules creates more total fuel molecules available for burning. This results in a fuel that has a higher vapor pressure and that burns more efficiently. More efficient burning results in more horse power, higher gas mileage, better fuel economy, lower operational costs for the vehicle, cleaner burning fuel, less exhaust emissions and less air pollution, less carbon build up and less fouling of fuel injectors and the cylinders, and lower vehicle maintenance costs.
While the invention has been described with a certain degree of particularity, it is manifest that many changes may be made in the details of construction and the arrangement of components without departing from the spirit and scope of this disclosure. It is understood that the invention is not limited to the embodiments set forth herein for the purposes of exemplification, but is to be limited only by the scope of the attached claim or claims, including the full range of equivalency to which each element thereof is entitled.
