Just wondering if anyone has an idea of what would happen if you injected Hydrogen peroxide in the intake? it has a makeup of H2O2. any ideas?

Your intake will turn blonde and the car will give you nothing but trouble.


(Sincerest apologies to any 'blondes' out there.......really.)

fastrotaries

it would be dissenfected!

same as filling up your tires with helium, because it has a lower atomic weight than regular air.

SaabGuy

ive done this before.

saabguy...dude...you're like my fvorite person on earth because of your avatar...it's nice that you're doing what you can to make us all happier...

so.... I take it this is something that can't be done?

ponykiller

What do you want the hydrogen peroxide to do?

nonameo

well here is what I was hoping. it has a similar chemical makeup to water. I was thinking that it would cool the charge like water does while also releasing some extra oxygen, but not so much as N2O does. plus, it doesn't have to be pressurized like n2O does.

BlackRx7

well If your a chemist you know that it requires certain chemical reations to break apart molecules

SaabGuy

Ya no problem. Those are saabs in the avatar, not rx7s.

I believe that you have to spray H2O2 over a platinum mesh in order for it to release its oxygen. Also you have to have a strong concentration of peroxide to get any real benefit.

nonameo

ok well then I guess its a no go. No I am not a chemist. I was just playing with an idea.

so what other fun stuff can I inject into my intake?

Look up propane injection. You might like what you find (if the ******* Search will work.)

H202 decomposes to h20 + 02 under ambient conditions slowly, much more rapidly in high temperature conditions, and even faster in the presence of a catalyst (such as maganese dioxide). Go ahead and try it, i would be interested greatly, these people don't know anything, pm me if you try it.

suds7 I PM'ed you.

Yes, it does exactly that. FYI hydrogen peroxide has been used as a fuel for over 100 years. If you want to inject it into your engine, don't mix it with the fuel, but rather use a separate system like water injection. An internal combustion engine can't run on pure hydrogen peroxide, so don't try it.

The hydrogen peroxide sold at the drug store is only about 3% concentration, and is therefore basically worthless as a fuel or additive. High concentrations of hydrogen peroxide react very badly when exposed to some things like silver, so I'm not sure if this is a good idea for someone who is not a chemist. If you look around, you may be able to find a 20% solution which would probably be better for injecting into an internal combustion engine through a water injection system.

I may experiment with the peroxide injection, but I am afraid of corrosion right now...

I am working on a non- pumped water injection deal (in my head) that uses a pressurized air container to atomize water through a side fed injector, or more properly a spray nozzle.

Really what my problem is that there are so many aftermarket people that want you to take it up the *** for their parts. I like to do things myself, too and so DIY projects are something I like to do.

I will try to draw up what I have in mind and post it later.

nonameo

ok, here we go.



its very crude, but you get the picture. surface tension would keep the water from coming out when it was not injecting. a check valve would keep it from getting sucked out under vaccum.

EDIT: yes, I know, water can't be compressed. The water is not under pressure. If you wanted to though, I am sure that it could be made to where both the warer and the air are under pressure and then force the water into the airstream.

nonameo

ah wait nm there are a few problems with that. Water would have to be under pressure, and they would both have to release at the same time.

MrBob 86

Why not use the pressure from the turbo to pressurize an injection system? You can use the pressure from the turbo to pressurize the water tank. Then run a line from the tank to the inlet side of the turbo. Put a check valve in the line going to the inlet side to keep vacume from sucking air/water back into the engine when you let off the gas.

nonameo

Can't do that. You would only be able to build up the pressure that the turbo could provide, which is the pressure that needs to be overcome.

MrBob 86

I dont think you understand what I am saying. You use the turbo to pressurise the water tank. Then you run a line from the tank to the inlet side of the turbo. The pressure from the turbo pressurises the tank, which forces water out of the tank and through the line going to the inlet side of the turbo.

Mmm.. Rocket Fuel injection.. Peroxide.. thought to be the cause of the sinking of the Kursk... the attributed cause of the death of several German ground crews late in WWII (iirc)...

Have you given thought as to how you'll obtain the peroxide? (The US is pretty tight-fisted about it in useful concentrations)

Anyway, the rotary engine is known for being bulletproof against things like detonation, I can't see how rocket fuel injection can go wrong!

:p

I think you're trying to reinvent a jet pump with your diagram there..

anyway, it's good creativity.. keep thinking.. but I'd be surprised if a peroxide experiment ended happily. Maybe even surprised if it ended safely! (if you got ahold of a strong enough concentration of the stuff)

Maybe I'm missing the point of exactly how you intend to use it, though...

Josepi

You got me curious about the peroxide as a fuel...

Now I'm reading about creating it...my gf has taken some organic chem classes...she's a good helper!
