Fuel vaporization could boost gas mileage, cut emissions

1/27/2009 11:32 AM EST

If this company claims to have independent test performed that confirm their claims of 30% fuel savings with no loss of horsepower, they need to publish those tests on their website (those tests docments are conspicuously absent on the company's website.)

In other words, it's time to put up or shut up.

A quote from the test company's research director that conducted the test isn't enough for you? Why would you need to see such test documentation? Reading both the companies web site, this article, and the other posted on their news page (which it looks like you failed to do) would indicate that they have all ready "put up". Who are you to say what a company need to put on their web site? I didn't know there was an Internet Police, perhaps you have a badge number? So, Mr. Broccoli, where is your fuel saving device, patents and independent test result? I see you failed to post them.

This does sound on the edge of too-good-to-be-true (and you know what your mother said about things that sounded too good to be true) so I am going to follow up in 6 months -- if the numbers are true this will have made a big splash by then -- it not, their web page will remain static. I will also try to determine whether they are using this annoucement to bring in investors.

when you say "The same fuel mixture enters the engine, but because hotter air occupies more space and provides more power, it enables a simultaneous savings in fuel economy and lower emissions." you are contradictating yourself. If the air is hotter and occupies more space, then you have less mixture inside the cylinder (a constant volume unit) and you should have less maximum power output from the engine. If your engine is a large one, you can get savings because you also reduce the drag associated to the vacuum in the intake.
I'm not a engine expert, but I think the same work could be done with variable intake valve timing.

Oh, no. Not another one. Doesn't anyone think that if it was that easy to improve mileage and cut emissions, that car manufacturers with their millions in research dollars would have done this twenty years ago? This inevitably will turn out to provide little to no improvement in either fuel economy or emissions except by the fuel savings gained by lightening the wallet of the consumer.

Maybe the people who currently do aftermarket re-programming, (chipping) of ECUs for more HP and torque can do a higher fuel economy version of their software...

To answer why I think test documents should be made available:

1) If the test data proves out the inventor's claims, it would only be to the inventor's benefit to make the test documents available.

2)There's huge precedent for supposed fuel-saving gizmos that just somehow never pan out.

3)Modern engines already burn fuel 98-99% completelly, so there just isn't any room for this claim of 30% improvement in mileage of a car retrofitted with this vaporization system. See this link for more explanation of this point:

So since the inventor's claims don't make any freakin' sense, I think it pretty reasonable to ask for the test data.

between the hydrogen generators, fuel catalysts and other things that never seems to make it to the big market its easy to be a skeptic, but you never know until you try it. however i am curious how they can claim a more powerful combustion by displacing gas with hot air, everything i've learned about cars says that cold air and a leaner mixture creates more power...but warmer air improves milage since less fuel is needed to keep the air fuel ratio consistant

im also curious about how they could control their "auto ignition" without causing premature detonation

Heating the air to force the evaporation of the fuel may give better mileage, it will also cause a serious problem with pre-ignition and detonation in the cylinders. When the piston compresses the air/fuel mixture, it will cause it to heat up (basic physics). If it is pre-heated "to near the point of spontaneous combustion" the added heating of compression will cause pre-ignition which will cause significant damage to the engine. Then there is the issue of getting the same amount of power out of the engine. By preheating, the mixture density is lower giving a lower combustion pressure. The result is a lower amount of power from the air/fuel mixture. The F150 in the article will have a very hard time trying to pull a trailer with this type of fuel system feeding it. The full amount of power of a carbureted or fuel injected engine will be impossible to achieve with this system.

"Work to Ride",

GM had an experimental intake manifold and carburetor in the early 1950s. It somehow got into a production 1951 Buick Roadmaster that reached a dealer in Pittsburgh. The car was sold to a local man. The man came back to the dealer for routine maintenance and raved about how he was getting 35 miles to the gallon. A short while after, representatives from GM came to acquire the car back from the dealer. When they found out the car was sold the GM folks approached the buyer to buy back the car. At first the buyer wouldn't sell but eventually he did. In case you didn't catch that, this was a Buick Roadmaster. That's a big heavy car with a V-8 engine.

Here's another one that made it to the market by accident.

When you heat gasoline, it either expands in volume or the pressure goes up or a little of both.

These guys appear to be fiddling with the gasoline/air mixture temperature. When heated, the gas/air mix expands so that it takes up more space, same ratio of air to fuel. The air/fuel ratio is not changed.

Smokey Yunick did this also, but, I think his patents have expired. In Smokeys case, he was heating the air/gas mix with engine water heat and exhaust heat. Once you get it to a high enough temperature, it is really expanding "fast". And you end up using waaaay less fuel even with the same A/F ratio. If you keep the velocity up, like he did with a turbo, and a fixed manifold size, you also end up with pressure boost. So, in Smokeys case, he boosted the pressure and the air/fuel temperature. And he did it all with waste engine heat, thus increasing the adiabatic efficiency.

These guys are using alternator current to provide the heat. But, they are only displacing some of the air/fuel mixture with their hot vapor. Smokey heated the whole thing up. Smokey was able to get almost 250 HP out of half of a Buick V6 (3 cylinders), and was getting 48 MPG when it was put into a Buick Skylark using a automatic with no overdrive (If memory serves).

What these guys are claiming seems very realistic to me. But, I'd like to take it a couple steps farther myself. That is, if they are willing to work with me on it. Gene Climer, Beaverton, Oregon. climer97007@yahoo.com 503-642-2017 (H) 503-267-1648 (M)

I have heard that the bmw sirl flap enables more oxygen to get into the engine, enabling better fuel burning. If this fuel vaporisation technique can further improve burning, there will be less carbon emissions.
