just wondering if anyone has tried one of these and if so do they do what they say???

It works on the same principle as your Coleman camp stove-heat the liquid to a gaseous state before burning. GM had used a more practical adaptation of the same principle. They developed a heated grid that went under their one barrel and Vari-Jet two barrel carbs. As the gas came out, it was vaporized by the hot grid. If you have an EGR tube right under the venturis, the hot EGR accomplishes the same thing of totally vaporizing the gas.

I read the fuel economy "gains" on that website. I'd be hard-pressed to believe them. Believe me, the EPA would be making a lot of noise if it were true. If the inventor were REALLY SERIOUS about his invention, he'd submit it to the EPA for lab testing. The EPA's seal of approval would make him filthy rich if his claims held up.

Hot carbs using the Coleman stove vaporizer principle have been done before with great mpg numbers, but perhaps they weren't very drivable. It's easy to control and meter a liquid. There might be a problem in metering vaporized gasoline and that might be why it never caught on.

 

yeah i thought those numbers were a little hard to believe too.

I dont know if their product would work or not but high mileage carbs are no fluke. They all work on the basic principle that liquid will not burn only Vapor. I have been working on high mileage carbs for a few years now. The best I have done was on a 10 Hp lawn tractor that ran on pure vapor. Its just hard to make enough vapor to run a large v8. There are many ways to get the vapor heat the fuel, whip the fuel, or the latest ideas use an ultrasonic transducer. An ultrasonic transducer vibarates at high frequency and when the fuel comes into contact with it the fuel vaporizes. Gasoline has a range of C3s-C12s. Since Gasoline is a blend it does not all burn at once. Ignition of gas is about 430F Gas starts boiling at about 130F on up to the ignition point. When ignition occurs the molocules with the lowest boiling point burn first then the heat they produce burn up another set. This chain happens until almost everthing burns. The problem is by the time the the molocules with a high boiling point burn, the valves are already open and its just burning in the tailpipe or in the catalitic convertor. Since the gasoline burns at different temps the explosion is a long hot explosion. The ideal explosion would be a fast low heat explosion. Almost like the explosion of Tnt, it makes little heat but moves alot of air. This is because the molocules all have a similar boiling point and ignition point. After the gasoline is vaporized it is introduced to a catalyst. A catalyst breaks down the gas without breaking down itself. what you end up with is more C3s and C4s (Natural gas) the procces needs to happen at about 900 degrees with the catalyst present for it to work.

Thats a mouthfull if you want more info I can email it to you.
