If John Weston of Port Charlotte, Fl. can get investors to take his gas-saving invention to the global automotive market, it just might solve the problems of smog, global warming and the high cost of foreign oil.

Weston, 48, claims to have invented a device that can turn virtually any car into a gas-miser that can run as far as 500 miles on a single gallon. Called the Air vapor Flow System, or xperts skeptical. The automotive industry has made strides in the past 10 years to make cars that produce less of such smog gases as hydrocarbons, carbon monoxide and nitrogen oAVFS, the device functions by vaporizing gasoline before it gets inducted into the engine. That saves fuel and reduces pollution because it allows the engine to burn more of the fuel that gets sucked into the combustion chamber, he contends. Emissions alone would be reduced by 76%

The device works on small, industrial engines or larger automobile engines regardless of whether they have carburetors or fuel injection systems, according to Weston.

Weston has been working to bring a prototype of the invention into more advanced development since the late 1990s. After encountering some financial difficulties in recent months, Weston is now renewing efforts to find investors. “My setback has always been financial,” Weston said. “That’s why I’m totally open to sponsors, investors or purchasers.”

The device consists of a small, plastic tank that gets mounted under the hood of a car. Some hoses from the engine’s air intake housing are run to the top of the tank so that the engine draws in vapors from above the level of the liquid gasoline. It also has some additional features that affect its efficiency and safety that Weston is not disclosing.

In an impromptu demonstration conducted for this reporter last week, Weston installed one of the devices into his battered 1992 Geo Storm, Scientifically, the results can be described as intriguing but inconclusive. Weston’s car ran well on the vapors from the device when the level of the liquid in the tank was within a certain margin. The engine ran either too rich or too lean when the level was above or below that margin. Weston is convinced that the car traveled 14.8 miles on about 4 ounces of gasoline during the test. If accurate, that would amount to some 473 miles per gallon.

However, an exact measurement was not obtained due to the testing method. That’s because, to operate the engine, once the fuel level dropped below its optimal margin, Weston briefly triggered a homemade switch 15 times. That pumped in additional fuel from his car’s regular fuel tank.

After the test, Weston estimated the amount of gasoline consumed by measuring the amount of gasoline that was added from his car’s regular fuel into a measuring cup. The fuel measured 4 ounces. Yet to be perfected are ways to maintain the level of liquid fuel in the vapor tank, and a way to adjust the mix of air and vapor while driving. With those developments, the vehicle would likely get even better mileage, Weston said.

Weston recently tested one of his AVFS tanks on a gasoline-powered utility generator. Without the device, the generator ran for 3.5 hours. With the device, it ran for 14 hours on the same amount of fuel, he said.
