Peroxide injection

[mopar2ya]

Since Hydrogen Peroxide has an extra oxygen molocule what would the end result be by injecting this?

water H2O
peroxide H2O2

where is larry???? hehehehe


i just found this link... interesting.

I have heard of some guys yapping about trying hydrogen peroxide injection. But, I dont know of any whove had the guts to try it yet Ive also heard about rocket guys using it, but also know very little about how they do it.

I am by no means a chemist, but the H2O2 (I believe) is an unstable molecule. If memory serves, H2O is much more stable and "preferred" so that when a certain temperature is reached, the H2O2 will kick out one of the O atoms and attempt to become H2O + O.

Also...for gasoline or alky injection, one is injecting hydrocarbons that naturally burn with oxygen and have the same products of combustion---


Gasoline C8H18 + O2 --> CO2 + H2O

Methanol CH3OH + O2 --> CO2 + H2O


With hydrogen peroxide, there is no C in the molecule, so the reaction wont be the same as we think of when a fuel burns in the combustion chamber.


Heres a decent site showing how hydrogen peroxide and methanol acan by use together.

I know that pure H2O2 will melt your skin off, the Germans used it in WW2 in the Misquito (rocket plane), but its really nasty in a pure form. I just figured if your shooting water you might as well throw in a extra oxygen molecule.....or not.

Yeah....pure H2O2 is very very nasty! I think the hydrogen peroxide you get at the drug store is like 97% water

I think you should try this H2O2 injection and tell us how it works! Just run lots of Torco for some extra safety

It also depends on what % you are going to use. The peroxide you find in your bathroom will vary from 3% to 9%. You can find 30% - 35% peroxide for use in hot tubs and swimming pools. Thought I wouldn't really mess with anything over 50% in a car. Hydrogen Peroxide will decompose into water and oxygen if heated over 80 C. Peroxide has been used before in engines like the German Walters test sums, but they were turbine. http://www.uboat.net/types/walter_hist.htm The same man that designed those subs and there power plant later designed a rocket engine that was powered by Hydrogen Peroxide and Methanol mixed with a catalyst.

Hydrogen peroxide is an oxidizer - it's loaded with oxygen. Usually mixed with alcohol, which we all know is a fuel. So when using the mix, you have to go richer on the fuel. Fuel plus oxidizer plus spark makes bang. The more fuel and oxidizer you get in the black box the bigger the bang. It's like nitrous but it's mixed with the fuel in the tank. Dirt trackers back home in Arkansas used it, which is illegal per class rules.

Someone needs to try this before I do. I had a moped back in highschool that I ran nitro fuel in. (the kind that the R/C model airplane engines use) I believe it was the fastest moped east of the Mississippi, until the piston melted.

A clean and disinfected combustion chamber...? might be handy if you launch a piston out of the block and into your chest...

[Frank]

oh my.... that would make a good safety video....


sorry, we had a safety standdown the other day..

Some chicks like it blonde..

If I remember correctly, Hydrogen peroxide also sank a Russian nuclear Submarine(Kursk?).
