I was watching Discovery chanel the weekend and it taught me how to make Oxygen!
You take some Hydrogen peroxide (HTP) and place a peice of metal in it. I think it is brass. the metal reacts with the HTP and creats O2 and water vapor. it does this at an amazing rate of expansion of 4000 times per second.
do you think this could be used for performance?
this is what I thought. You take a jug of some kinde with a wide mouth. fill 1/2 full with HTP. the lid has a hose that is directed to the intake path. the expanding gasses shoot directly into the intake. for safety reasons you might want to put a vent in the bottle too. I saw a
glass tube explode on the show.
It might be better if you put the tube before the filter. so you don't mess with the MAF.
This is really far fetched but if anyone is brave let me know what happens.

 

If memory serves me, try dropping a bar of lithium in the same HTP, and watch it blow half the room away.

 

lol no way man you would have to have like 100 gallons of htp for a few 1/4 mile passes.

 

Saw that show also, too bad the vapors coming off the liquid were water vapors! Otherwise it would work, pure O2.

 

Like the way you think.

Keep it up.

 

No. BAD IDEA. You never want to send pure O2 into an engine. Otherwise, why not just pour in pure oxygen from a ntirous bottle instead of the used 36% oxygen content? You need the nitrogen in the air (or nitrous oxide) to act as a buffer, to prevent uncontrolled gas explosions. It will prevent the motor from popping. Also, there would be no way of metering the amount of extra oxygen entering the system, and the motor would go lean.

Not to mention if that O2 every happened to ignite...I hope you signed your will!

hte hydrogen peroxide they where using was most likly around 40% take a look at what you have at home in the brown bottle its only 3%. you need to be in a science lab or have a good friend in one to get nething more potent than 5%. good luck and try not to blow yourself up. hehe

 

where did you get HTP from??? hydrogen peroxide is H2O2 and if you are making O2 you are more than likely gonna have H2 in there. i dont know the exact experiment you are talking about but throwing pure O2 in your block is a bad idea.

the O2 cant "ignite" but it would make the fuel very volatle (sp) and you would ping an apex seal in a heartbeat. but if your car ever catches on fire and the bottle breaks, you might as well kiss the whole thing goodbye because by the time the FD gets there all you will have is some bolts in a pile of ash.

ok now just think about that expansion rate......

Ahh dont listen to them. GO for it. Just make sure you have a derby helmet on and have your friends take lots of pics and promise to post them here!!

 

While oxogen itself doesn't burn it supports combustion to such an extent that normally non flammable materials rapidly oxidize (burn). Add heat and combustion from the engine into the equation and yeah probably everything on the RX-7 could burn. You do know how a cutting torch works right, little torch to make molten iron, then introduce a stream of o2 and watch it burn!

 

[snip]

Obviously you haven't messed with an oxyacetylene outfit...
As BLUE TII mentioned, the pure O2 would accelerate (obviously) oxidation.&nbsp If you ever get the chance to mess with gas welding, heat the metal with both gases and turn off the acetylene gas and the metal will "miraculously" still burn...

Pure O2 and sparks is a dangerous combination.



-Ted

 

i know what O2 will do. but if you throw a spark into an enclosed pure O2 environment the oxygen will not ignite. it needs a flame for it to burn. the reason the metal still burns is because it had the flame of the torch to start it off. but my point was that Oxygen is non-combustible. it only accelerates burning and causes combustible materials to combust. so no, O2 will not ignite, but it will cause other materials to burn ridiculously fast.

in Apollo 3 i believe it was prolly another mission. (the one where the three astronauts died (their names escape me for the moment)) the reason they all burned to death was because they were in a pure oxygen environment. all of the materials in the cockpit had been tested for burn rate and were all fairly safe. but they had all been tested in a natural air environment. when this happened they did some testing and the velcro burned at incredible rates (almost explosively) in pure oxygen. this accompanied by the fact that they couldnt get out of the pod is the reason they died. a spark had touched the velcro.

Justin

 

So you're going to tell me you're going to suspend the spark in mid-air until ou dissipate the O2?&nbsp The spark is either caused BY something or going to land on SOMETHING.&nbsp Either way, it's going to cause one helluva fire...

WORST ADVICE EVER. That's like encouraging someone who is suicidal. Why not just tell him to lower his fuel pressure to 5 psi and rev the engine as high as possible?
If it doesn't screw his engine (which it would), it would possibly explode and kill him.
Do not listen to this guy on this topic! This is very bad advice. introducing O2 into your engine to ignite is dangerous to your health and to your engine. Do not do it.

MIght as well get a J.A.T.O. pack and rig it to your 7. Should hit terminal velocity in about....ummmmm...a tenth of a second?

 

ok forget about the spark. throw a lit or smouldering match into a O2 environment and it will flame up and burn very rapidly, not explosively, just rapidly, and if it is smouldering it might light back up or it might just smoulder into ash. either way the O2 will not ignite and in the end most of the O2 will remain. it will only burn as long as there is a combustible material other than the oxygen.

Justin

 

LOL!!
I wondered what you guys would say. That is funny stuff. I would never try anything like this. (or encourage suicide) I just thought it was cool that a normaly very stable product could be made be so violent. any way, have fun guys. and don't try this at home.

 

Whats the "normally very stable product"? Not H2O2, for sure. As someone said, you can buy 3% solution-high concentration stuff is very nasty! Early liquid rocket fuel=H2O2+Kerosene.

 

Peroxide is one of the most unstable and dangerous compunds in existence. I would honestly rather play with a water balloon full of nitroglycerine. In concentrations below 20%, its pretty dosile. Above that is asking for trouble if you don't know what you are doing. The hydrogen and oxygen really don't like being together, and are looking for a catalyst to give them an excuse to be freed from eachother. Usually that happens explosively. If you were to throw any organic (charcoal for example) into a highly concentrrated H2O2 solution, you can count on it releasing oxygen so fast that an explosion occurs. If you ge the stuff on your skin, it acts like acid and will burn you badly. The most concentrated H2O2 that you can commercially buy without a liscence is sold in swimming pool shops under the name "Baquacil". Its a "chlorine free" pool sanitizer and is 30% peroxide. Though it would probably be cool to see, I wouldn't recommend dumping it into your car since someone will probably be killed in the process...not to mention thats a waste of a good rotary!
