Increase MPG or BS?

[knucksfirst]

Ive been seeing these Hydrogen kits popping up everywhere claiming they give you better fuel mileage. Im just interested on you opinions and what you think. If its a maybe I might just try one out just for shits. They are pretty cheap. Post what you think.

How about you post a link to what you are talking about.

Look on youtube its all over the place.

Look on youtube its all over the place.

You asked the question... If you dont want help, thats cool by me.

Look on youtube its all over the place.

You've answered your own question. Its been asked so many times here in general discussion and in alternative fuels i've lost count.

Don't know what it is. But it sounds like its gonna be some expensive BS to me.

(Physics and Electrical information ahead from an Electrical Engineer)Hydrogen generators work, but not on a scale large enough to affect fuel mileage to any great degree. If they did, there would be power generation plants running on it, instead of hydrocarbons.

The principle is to break water to it's component parts and use only one of them - hydrogen. The problem is keeping the molecules separate once the bond is broken. The Oxygen and the Hydrogen almost immediately try to reunite and stabilize.

The process is done by electrolysis, passing electricity through a solution. You have to produce electricity (alternator), which means almost all the power added to the engine by hydrogen (very small amount) is used to turn the alt to produce more electricity to make more hydrogen ... not used to power the wheels.

All in all, a good theory not perfected for practical use, and not worth the money and added complexity.

Mythbusters already tested these things and almost blew themselves sky high in the process.

It comes off the same shelf as the carb that promises 100 miles/gallon as well as those stupid little pill things that you pop in your fuel tank that are supposed to give you better mileage.

Best thing you can do to help fuel mileage: 1) Don't drive like a moron 2) Proper maintenance...preventative or otherwise.

First law of thermodynamics: You can't win.
Second law of thermodynamics: You can't even break even.

Anything that breaks these two is BS.

Any time you convert energy from one form to another, you lose some.

We also need to remember that a high percentage of the energy from the gasoline is blown out the exhaust as heat, instead of pushing down the piston.

I suspect that the way these kits work is by transferring water into the intake, allowing the gasoline to burn more efficiently. Remember that water expands a lot more than air for a given temperature rise, and also that it takes a lot of energy to boil it. Therefore, it will create a higher pressure at a lower temperature, when burned along with air in an engine. The higher pressure transfers more of the available energy from the gasoline to the piston, and the lower temperature reduces the tendency to ping.

However, they're doing it the stupid way. Water injection kits have been around for years. Just introduce a little water into your intake and you could do the same thing a lot cheaper.

Has anyone noticed how your mileage seems to go up when it rains?

Oh boy... Here it goes again... Definite no... It breaks the laws of thermodynamics...

 

[rusty70f100]

I just don't think it's doing anything more than one of these:

See, they've been around for years. I just don't think it's the hydrogen.

On a small engine , say a weed eater or a lawn mower...
Absolutely. HHO generators can absolutely sustain them.
Mainly because there are no accessories and the worlds smallest electrical system.

What most promise from HHO is impossible. It is impossible to create energy from thin air with out robbing something else of the same energy.
HHO generators rely on electrolysis ( essentially ). Electrolysis require the presence of electricity. In a car that comes from the batteries and the alternator. The engine turns the alternator which makes the electricity. The battery stores it.
A problem exists.
The motor has to be running a head of time to charge the HHO generator with voltage from the alternator. The problem with HHO generators in general for use in the automotive industry is that they do not produce enough HHO to power the engine to the point of replenishing the energy it takes to operate it. Just like fossil fuels.
As well it takes fossil fuel to jump start the system to begin with.

Snake oil.

No, No, more no, one more no followed by a thousand no's. you wanna ease some pain at the pump? think of one of these retarded ass scams and make a million bucks selling them, then money wont matter

If youre talking about a bubbler its not true hydrogen, it's Brown's Gas AKA Water Gas. It's basically electrolysis and it takes more battery energy to produce than it gives off. I built one of these as a Chemistry project years. The only practical application that it has been used for is a cutting torch, because it burns clean. True hydrogen technology is on it's way but it just isnt cheap enough yet to mass produce
