H2O2 injection, how? i need a full rundown!

[bobjoe]

hey
with gas prices sitting where they are i thought id try and run H2O2. i heard that it double fuel milage and pulls the horse up quiet abit too. how do you do this, do i just need to place a bottle somewhere for the H2O2 and an injector in also, not a clue where this would go tho.
does anyone have any personal experiences with H2O2? i would think that a person would have to make the H2O2 concentration higher because the stuff you bu at the store is only about 4~7%, that wont be close to high enough to start running partially on. i think, from a little bit of past reading on it that it works like alky injection in the fact of you arent running soully on it. my other thought to it also is that if say you have a 90% H2O2 and 10% H2O mixture wouldnt the H2O help by cooling things down.
i dont know for sure about this thought but i think that the H2O2 breaks down in the cylinder due to the heat and then burns to become H2O vapor, note that this leaves on O left unburned so that would also help with the burning of the fuel. if this is the case (i dont know for sure but ive been trying to figure this out for a few days now and this is where im sitting) then shouldnt you be able to cool down the exhaust fumes so the H2O vapors become a liquid, then you put it in a tank and give it a good joult of electricity, seporating the H2O up into H2 and O2, you could then add a little bit of that to the mixture and reuse the waste, once you get the cycle going a little bit you wouldnt need to put as much H2O2 in from your main tank in the front causing that to last longer
i think my main objection with going this route is that if you do get better fuel milage, you get less boost, which really kicks our cars in the nuts cause thats what makes them soo much funn
maybe im crazy, i dont know, just a thought
thanx for any help

The reason you only can buy a 3-5% solution is a purer form of peroxide is very corrosive and the vapors are very flammable. The downside really outweighs any benefit. if you want inject some methanol, but it wont do anything for mileage.

wasn't peroxide banned from NHRA drag strips back in the 50's or 60's?

[scott_s]

You should be able to find 35% pretty easy with a little bit of searching. I use 35% to shock our well instead of bleach. It is one of the most powerful oxidizers known.

Hydrogen peroxide itself will not burn, but its decomposition liberates oxygen which supports combustion. Have worked at a plant where I made peroxide, if you get any on you wash it off with water. 35% can turn the skin white. Higher percentages can leave scars, though, they seem to fade with time.

[Phreakish]

and its UV sensative, and the corrosive nature of it could be damaging to an engine in large enough quantity to see many benefits I would think - any pooling of it near/around steel and iron can wreak havoc - not to mention blow-by in the engine, the increase in water in the combustion mix would also do a number on the oil...

Want better milage? put a throttle body on thats half the size of stock, and put an intake hose on your inlet that sucks air right off of the exhaust manifold. It wont make beans for power, but you'll get better milage...

How is extra oxygen supposed to burn less fuel? More oxygen demands more fuel.

[bobjoe]

hey
(most of this is me tired and trying to get things straight)
it doesnt burn less fuel, it just burns it more completely
when you burn gasoline i think the mixture is ( this is just octane here but...)
2 C8H18+ 34 O2----> 16 CO2+ 18 H2O
thats a whole crap load of oxygen being suched into the engine just to burn a little bit of fuel. because there is soo much oxygen needed to support that amount of fuel, and 9 times out of 10 the car cant supply that much air, you get incomplete combustion which gives you CO and also with the impurities that are being sucked in also, like sulfur, you end up with other things like SO4 and such. all the H2O2 does is give you that extra oxygen needed to burn gas. the atmostphere only has 20% oxygen while H2O2 has 50% oxygen, thats 2.5 times more
sorry i know i gave a long explination and ill put money on it says you knew that already but im still trying to get my head wrapped around a few things, my appoliges
sorry if this bored you
have funn

Then again adding that much more oxyen and no additional fuel can make a much leaner mixture, which under load makes things get really hot and go bang.

Incompatible Chemical List

[bobjoe]

hey
what does this list mean?

He is pointing out that it reacts with iron and most metals. I know when I spilled it the nails in the pallets would react and sometimes smoke. Lower percentages, it was not so bad. The good thing is the cylinder will have oil on it protecting it, and it is not like the H2O2 will be pooling on anything long enough to start reacting, hopefully.

If you are in Edmonton, I know of only one place that has 35% and for the cost, I would not think it would be worth it. Gas is still cheaper.

I remember when a supervisor got some high percent H2O2 in his boot. He kicked it off so fast it ended up in the tank of H2O2. When he went to get it out, all that was left was the rubber sole. I do not remember the percentage, but I think it may have been 75 or 80%. And then there is truck that was destroyed because a nail from a pallent put a hole in a drum of some high percent stuff. The driver was ok. Or when a teak planked sea container with planks that were close to a foot thick was turned to mush. Of course there was enough in the air that any hair that was not under the hard hat was bleached.

When in contact with some metals the resulting gas expands pretty fast ... like "be somewhere else" fast.
... expanding gasses = extreme pressure

Yes, it does react in direct contact with some metals. That's how a H2O2 rocket propels itself. The fact is, I'm already set up with Water Injection. And yes, I will be doing dome testing with the H2O2 BEFORE I put it in my system. My car is a NA '04 SX 2.0, and a cheap WI system does help with the fuel economy too, about 15% right now.
