Check this out!!! Save 9-15% on fuel

[jbach36]

This works on diesel, too.

Go to this link, and click on what is now the 2nd link down (that will change in time). Works with diesel, too......

Don't listen to these guys below, who immediately claim it's snake oil. The video goes over some 16 vehicles, all of which have gotten a 9-14% fuel savings.

This time they didnt bother to remove the oil from the snake!!!! Just selling the snake !!!
It wont work!!
Save your money !!
The ideal contraption for some one who is desperate !

Placebo effect, drivers are aware they have a device and change their driving habits. Take the device out after 2 months without telling them, and alas, the savings are still intact!

Does the snake go directly into the tank, or do I put it somewhere else in the car?

[jbach36]

The Paulding police have already installed them in 6 cars, and the lawn service guy in 10 trucks.

This is not a fluke, that everyone's coming up with a 9-14% savings.

Further, the video tells you in a round-about way, it works by providing the fuel in a more misted way. That's what happens in cars anyways; it puts a mist of fuel in, mixed with air. What this is doing, is putting the fuel in with higher pressure, and less fuel, giving a slightly more efficient mix.

I don't know why this is so hard to believe. Misted gasoline (vapors) is more explosive than liquid gasoline. Makes perfect sense to me, but I'm not an engineer.

Nate,
It looks like you ram one end of the fuel line down its throat & the other fuel line goes .......... never mind!!

End up with one angry snake!!

I wonder if its got magnets in it as well?

MB diesels already get 50mpg so there could be a real danger to using one of those things. Size it wrong and it could actually make fuel which could spill into your trunk and back seat...

A little knowledge can be dangerous. If you mix air with diesel, injectors wont work.
Do you have one of these "snakes"? My guess is there is not much in it.
I wonder how much the inventor paid for the news story?

As soon as they showed it was in Texas, I called BULLSHIST and stopped the video.

Hey Pelon, all Texans aren't stier-shiebe artists.

Anyway, I too have to call em on this one. Increasing pressure inside of the fuel stream on a gasser may cause greater atomization of fuel but it better not have air or oxygen injected in the stream. You might create a large fireball if you're not careful. Also, changing operating parameters on today's computer controlled sensor monitored injection systems may cause the computers to compensate possibly negatively.

As suggested by Layback40, air in the diesel will cause many problems. If the fuel becomes increasingly compressible, inject-ability suffers.

You'd likely get better mileage by getting your injection pump tuned, new injectors, new rubber on fuel delivery and return hoses, adjusted valves, greased bearings, well maintained brakes, etc...

I have my doubts on this device.....I've seen things that supposidly do the same thing on Ebay and it's all crap.

[Codifex Maximus]

I met this guy at an auto parts store in Dallas. (I *think* he might still be alive.) Anyway, he'd built what he claimed to be a hydrogen production device for his gasoline engine. He popped the hood and showed it to me saying it made hydrogen out of water by electrolysis.

I'm not sure it actually electrolyzed the water but when he went to start it up, I backed off quite a few feet. I did see some bubbling inside the device but couldn't be sure it was hydrogen or just steam.

I took no chances.

I also didn't have the heart to try to explain to him that according to the laws of physics, you get less energy out of a system than you put into it. I don't care how much hydrogen he produced, he'd not get back the energy he expended converting it. Now, if it caused a more efficient burn of the fuel he put into the engine then maybe...

Systems like turbochargers use waste heat from the exhaust to compress air to increase efficiency of burn - a positive gain. While superchargers rob crankshaft power to do the same thing - still a positive gain but not as efficient as the turbo.

You want to know why we're skeptical? For me, I've seen even more gas saving devices than I've lived through ends-of-the-world. I'd be more than happy to be proven wrong, but until someone I take serious like consumer reports takes a crack at it, I'll be saving my money to buy fuel.

I don't understand the chemistry but wouldn't combustion efficiency benefit more from more oxygen than more hydrogen?

This a great topic for Mythbusters to test.
I call it snake as well, minus the snake.
