Pseudo Nitrous/Water Injection Idea

While discussing the water injection system with a firend who is installing it on his engine, I had a crazy but
posible idea.

Instead of using water, use hydrogen peroxide. You would have both water cooling and more oxygen for combustion.

Has this ever been tried?

Chuck- on the bleeding edge. You've been hanging out at the hospital too long, hehe.

BTW, do you have chrome stock wheels on right now? Saw a BB on 59/Murphy a couple weeks ago...

Oh, and for the time being I'm going to squirt methanol with my aquamist kit. Is it ok to mix methanol with water? What would be an ideal ratio if so?

Daniel,

Unfortunately the hospital will not allow me to take recreational drugs. BooHoo!

I do not have chrome wheels. Mine are Enkei RP01s.

Methanol and water mix is fine, but I do not know the optimum ratio. I think it depends more on your AFR as the methanol will consume more oxygen and make the AFR go down. If you were running like 12.0 AFRs and added methanol then this would drop the AFR some besides the cooling affect and high antiknock value of both the water and alcohol. GM did it with some of their forced induction engines starting with the Corvair.
Maybe you can find some literature about what they were running.

Yes, hydrogen peroxide is half oxygen, but it's also half hydrogen. It's something to be careful with. I wouldn't try this one out.

From what I'm reading on the net H2O2 does decompose to produce oxygen, but is very unstable with heat. And will spontaneously combust. It has a boiling point of 108c.

Dclin: 50/50 is fine with methanol. There is lots of information on the net about that. Methanol mixes perfectly well with water. Though Methanol is corrosive, and will eat away at just about anything that isn't stainless steel, if it sits there long enough (rubber hoses, plastic resevior cans, etc).

I would not suggest the pure H2O2 as the Germans used in some rocket engines, but the common store varity which is only about 2-3% and is very safe.

2 molecules of H2O2 breaks down into 2 molecules of H2O and one molecule of O2. The hydrogen does nmot enter into any chemical process during this. Just O2 is released.
