oxy enrichment

[LYLMIK]

HI ALL!!!

This is possibly the dumbest f*****g idea someone ever came up with.
Since the whole NOS issue is so bloody illegal and all that crap, i figured that i might ask some of you pros if it is possible.

The question is: can you install oxy bottle instead of NOS and so feed ity into the air intake? Since oxy is only(probably wrong, but close enough) around 20% in volume of air, nitrogen around 70%something, and miscelaneous gases the rest, what would happen if the oxy feed would knock it up to maybe 40-45%?

I know the result could be either melting the f**k of the engine or losing your knees and better part of the face in a bang, but really wonder, any clues?
I know it must probably be the dumbest idea so pease don't bag me too much, 'm very new at this.
Thanks!

Forgot to mention, the whole point of the exercise being the increased, more vigorous fuel combustion.
Which could also end up in 50m radius total devastation.

what is the chemical composition of this oxy. gas?

The above was hard for me to understand the first time I read it, but if I get it now, you're stating the rough composition of air, and suggesting that it could use more O2, right?

The approximate composition of air (mole basis):

78% N2
21% 02
1% Other

I think we've heard 3 of the same idea in the past month.

I don't know about you but I sure as hell don't want a tank of compressed Oxygen in my car. Nitrous is one thing but Oxy is just too damn dangerous. And without the Nitrogen helping to cool the intake charge you would start burning very hot which leads to some serious problems.

Actually, the reason why nitrous cools the intake charge is because it's stored at very high pressures and ambient temp. Once the pressure drops, the volume increases and the temperature decreases significantly. Oxygen is also stored under high pressures and thus would have the same effect on the intake charge.

And nitrous would probably increase power even if it didn't cool the charge.

Apparently,what can be done to make it work is as follows(all this is thought of by my friend, if you can find the hole in the logic, please do share):do the same setup as for NOS, but install O2.
Huge injectors are the must, some time on the dyno as well.
Flood the engine with fuel while on dyno and keep making it leaner and leaner until you hit the proper mixture to still be richer without the bang.
Trouble is that the heat that will be produced by O2 induction will be much higher than NOS, since NOS is inert, but apparently as long as the fuel air mix is kept sufficiently rich there is very little chance of detonation.
Higher combustion temperature should also mean that the pressure will be much higher as well, by some rule of physics it should be working better than NOS, and O2 will be cold as hell just like NOS, so there shouldn't be too much of the temperature increase.
Whenever you feel like bagging me, please do, but remember that this is just an avenue i'm trying to explore, and the general idea is not so much the power upping if it does work, but to basically tell the copper that will eventually stop me to shove it up his ass, no NOS on board, just my oxygen bottle, keeps my buttcheeks rosy or something.

Your sentence structure is a little bit confusing, but I made my way through it. Now, "nitrous" is inert, but once you compress it (in the combustion chamber), it turns into diatomic nitrogen and diatomic oxygen, which is definitely not inert. IIRC, aluminum will burn in oxygen. There's just so many things wrong with putting pure oxygen into the combustion chamber...

BTW, you wouldn't have to do all that dyno stuff. If your engine could take the oxygen, you'd just use the oxygen sensor in the exhaust to determine how much fuel needs to be added, and the ECU does that anyway.

so what you are saying is it can't be done?

[LYLMIK]

and it wasn't intended to be pure O2, just enriched.
besides making the bang very likely with pure, the cost to run the thing...

Yes you can do it, and yes it will work.

BUT, the big problem is that just adding more oxygen and more fuel increases the combustion temperature which can lead to detonation.

The added nitrogen (which is inert) actually slows down the rate of combustion and prevents the charge from exploding instantaneously, which is what detonation actually is. So with nitrous oxide, you can add more of it before the whole combustion thing gets out of hand.

So if you put your engine on a dyno and kept adding more fuel, along with either oxygen or nitrous oxide, you will get more power with nitrous oxide before detonation destroys the engine.

Nitrous will give you more safe power than straight oxygen.

THANKS TONY!!!
i would probably end up actually doing it, and frying the living crap out of the engine.
THANKS HEAPS!!!
