"HHO" gas injected into carburetor - does it improve efficiency?

Question

I've seen alot of stuff on the internet about using electrolysis to turn water into HHO on demand, then injecting this gas into the carburetor (or fuel injector) of your car.It says it'll draw only 1-3 amps from your car battery, and yet produce enough gas to increase efficiency by 40 percent. Now...I know its impossible to get more energy from something then you put in - essencially, you are using the car's battery to convert water into this HHO gas, then burning it again which means you will only get as much energy out of the reaction as you put in...so...HHO gas burning by itself could not possibly produce more energy than the energy you put in it to convert it...BUT...is it possible that the addition of HHO gas makes the gasoline you are putting in your cylinders burn more throughly? Basically, my question is...is any of the stuff on the internet about HHO gas injected into fuel injector/carburetor to improve efficiency plausible? Could the HHO make the gasoline burn more throughly

Answer 1

It will give you a larger and cleaner burn. I don't recommend doing any conversions yourself however.

As far as 40% efficiency goes... I doubt it. However you can realistically expect anywhere from a 3-10% efficiency boost. Engines can only be so efficient. Most of the thrown away energy is heat and unburned fuel that could have been converted into energy.

You will get a noticeable increase of horsepower and torque because it does make for a much more more thorough burn-- which then yields more energy output.

Because HHO has more energy per unit mass while gasoline has more energy per unit volume. HHO gas acts as a catalyst that gives you more energy out than energy put in when you burn it mixed with fuel.

So in actuality the drain on the alternator for electrolysis/HHO injection is actually supplying more power to the engine and also the alternator because of this catalyst reaction increasing the power out.

Answer 2

It's just a con been around a LONG time (before the 1970's)

In a modern car you only have about 50 PPM (parts per million) of unburnt hydrocarbons left in the exhaust even if hydrogen could burn (it can't) that small amount of hydrogen you wouldn't notice an increase in fuel mileage.

Yes there is some research that does show if you used compressed hydrogen, not HHO, and tune the car properly you can increase the efficiency of the engine, but they are using much more hydrogen then you'll ever produce with a HHO generator plus they didn't use any oxygen, plus they re-tuned the car, you could increase the efficiency even more by using pure hydrogen and re-tuning it.

HHO generator produce a TINY amount of HHO gas just look at how often you have to add water to them.  Some are saying once a month you fill a tiny jar with water, just how much HHO could that make, answer not much.

Save your money.

But again it's a con, save your money.

Answer 3

I think here is your answer.

There is a One Million Dollar HHO Challenge on offer (see the website link below) where anyone who can prove a mere 25% or better improvement in fuel mileage as a result of fitting one of these HHO systems to a vehicle gets the chance to walk away with a cool $1m.

Now if the claims of those saying that you can "double your mileage" or get improvements of "40% or more" were true, don't you think there'd be a very long list of people signing up for that challenge?

But look at the page.

Not a single entry so far.

That kind of answers your question doesn't it?

I mean, who in their right mind would turn down a million dollars?

Answer 4

Nah, it can't work.  There's a nice answer in the question linked below where the guy tested such a system and it decreased his overall efficiency 14%, as you would expect.

Answer 5

Yes, because the reaction of H2 + O2 in combustion engine will create small energi that will improve the gasoline to be burn more effectively. So the energy to improve actually is not come from the H2 + O2 but from original gasoline that usually not burn. Basically the H2 + O2 reaction only serve as catalyst to make your the burning of your gasoline better.
