Theres this new car device that says it can greatly increase you MPG.
I'm very doubtful this would do anything more than cause problems for your car. I don't understand how this could theortically do anything for your gas Mileage
Heres the link: http://www.savefuel.ca/

Quote from website:
1. "the Hydro-Gen separates hydrogen gas from the natural hydrogen-oxygen mix in standard tap water (i.e. H²O). It then adds the resulting extracted hydrogen to the conventional air mix in a vehicle engine (e.g. gasoline, diesel, etc.) thus supplementing the expensive fuel with an additional low-cost"

At the bottom of the webpage they give you this Iron Clad Guarantee
"Should you find that the Hydro-Gen does not give you a reasonable level of fuel savings, return the unit to us, and we will refund your money".
How can you Argue with that?
Tell Me Your Opinions!

 

Hmm... Basically, you add water to your tank, and then it uses electroylsis to separate them.... Or is a separate tank used for the water? It would work, but I don't know...

If it does work, cool. If not, oh well.

 

It's an interesing idea, but I'm as curious about what he didn't say as what he did say.

- What is the unit's power source? Is it hanging off the electrical system? For the amount of hydrogen it would take to make an appreciable difference, he'd need a significant amount of power to separate it. Does it draw enough power to cause problems for other components?

- Electrolysis separates hydrogen and oxygen. What is he doing with the oxygen, just discarding it? If so, wouldn't it make much more sense to use the oxygen in the combustion as well?

- As Beodude123 mentioned, the water supply has to be stored somewhere. Where is it stored, and how much is stored? For that matter, how fast is the supply used up? Do I get 20 miles per gallon of water? How do I clean the storage tank, supply lines and hydrogen generator of the inevitable mineral build-up?

- How much real-world testing has been done with this unit?

- If it's such a terrific device, why only a 30-day guarantee?

Overall, I'm skeptical, and the amateurish Web site doesn't fill me with confidence. If someone else wants to part with their cash and try it out, I'm all ears. But I certainly won't be the first one on the block to try it.

 

I bet, if you track it down, it's a violation of the laws of physics. Electrolysis takes more energy than the combustion of hydrogen produces. Combustion is exothermal so the reverse should be endothermal and less efficient. Plus - you are adding weight to the car. It's like putting a windmill on your car to generate electricity while driving.

 

While the rest of your paragraph isn't very informative, this sentence is brilliant. (particularly if you are running off the car's elec. sys.) Too bad most folks wont understand what you are talking about.

 

It's not a violation of the laws of physics, unless you're talking about running the car on 100% hydrogen created from electrolyzed water by an onboard generator. There are several of these hydrogen booster setups from different companies, basically you run a bigger alternator and the machine adds a small amount of hydrogen (and oxygen?) to your fuel/air mixture. I believe the logic is, you're helping the fuel/air combust faster and more efficiently, since hydrogen burns faster than petrol. It might be particularly interesting for a rotary, what with the elongated combustion area and all. I don't know about this particular company though.

 

These cars have crap for gas mileage. Just accept it.

 

So I add hydrogen to my intake air, it passed by the MAF sensor, the ecu injects the exact same amount of fuel as usual since it has no idea that the hydrogen is there, and my mileage stays the same.

Or am I missing something .

Regardless, if it were that easy, the car would come with it.

 

1) it takes as much energy to "split" water into H + O than it gives when it recombines to make water
2) the energy use to split water is electricity
3) electricity on you car comes from the alternator, driven by the engine
4) only less than 30% of the energy released by the fuel burnt in the engine is transformed in driving force.

So, in order to split water and recover a given quatity of H2, you would need to burn at least 3 times more H2 in the engine to make the electricity needed.
And all this assumes complete loss free alternator and hydrogen generator.
