Me and a friend are having a debate and i wanted to ask on here to see if anyone knows some info i could use. My idea is to put an oxygen tank in my car and feed it into the intake. normal air is like 25% O2 and i was planning on just running a line to the intake tube to run a small amount of O2 to mix with the air to make way more combustion. My question is would this work or just detonate the engine. anyone that has some real knowledge of the physics of this please post some answers, if it works it would meen huge HP.

(edit...remove misinformation)

I wouldn't do it. But have fun with that fire if you set that bad boy up. Besides you would need fuel to match that extra O2 if it got into the engine without going boom.

Could work, but you would have to figure out a way to calculate the amount of Oxygen you are injecting and compensate for fuel. But it could not be sprayed like nitrous because oxygen as very high combustion temps and would up your EGT waayyy too much, that is why we use Nitrous Oxide, when the N separate from O it use a lot of energy, which is taken in form of heat, reducing the combustion chamber temperature. Welll, that's how it was eplained to me.

isnt NO2 extremely flammable too? i would be running larger pump to compensate for O2

By the way... it is N2O.

no and no.

The N in N2O is what makes it safe. Long story short... stop talking.

Yeah, you use oxygen, and you'll make it exceptionally hot. You'll probably blow the motor up before you notice any performance upgrade. Cutting torches use acetylene and oxygen together cut through metal. Acetelyn burns realy hot....But when you kick in the oxygen you make it reall really hot.

99% of the **** you saw in FnF isn't true. NAAUWS doesn't blow up. The bottles would have burst yes but the car wouldsn't just burst into flames and jump 10 feet into the air.

N20 Is explosive under pressure! so It could blow up if expose to high heat under pressure!
O2 is explosive easily... and you would not be able to control the fine amount of 02 you are injecting it would be super hard.
You will need more than just an fuel pump... Trust me! You need to read up on this alot more... there is tons of information on it just do a search!

If i was to only increase the amount of O2 in the air by only like 5% it seams like it would still be just as stable but more combustable

SpeedFreak03

Well the bottles would burst because of the high pressure that they are under. Also, the nitrogen in N2O provides cooling. Don't cheap out you will probably blow your motor and yourself up. There is a reason people don't inject pure oxygen into their engines .

Mint87RX7

i dont understand why the bottles would burst, normal oxygen tanks dont just sudenly explode. maybe if you could get a tank filled with 30% O2 like old people get to breathe

Templeswain

Well then you need to do some hard core math. You have the idea so now get the figures for it.

You'll have to find the ration of air to fuel your car currently consumes. Then, find out what a %5 percent increase actually is per unit volume of space at your atmospheric pressure. And what amount of fuel would have to be increased for every unit of oxygen consumed at that %5....And a whole bunch of other technical mumbo.

Sure it might be stable. Sure it might be more "combustable".....but your idea of "more" might be turn out to be .00000000000000000000001% increase in power.

I thought about how to shove something/anything into the intake to increase hp too. We all have at one point or another. But chances are, someone already learned this curve for you.

But its good to think about it, even if it doesn't work.....

The Nitrous works because the Nitrogen molecules act as a transport method to get the explosive/combustable oxygen to the chamber without premature detonation.

Heat and pressure makes Nitrous combust/break apart into nitrogen and oxygen

The reason why people use nitrous is 2 answers.
The nitrogen and oxygen seperation creates a cooling effect helping reduce intake temps.
Cooler air temp == more hp.

Then there's adding more oxygen into the chamber.

You add more fuel because your adding more oxygen.

Blah blah blah. I'm not a pro at this. If I'm wrong feel free to point it out.

Your WRONG... lol.... Just joking...
What Digi7ech said is short but entirely true... the reason n20 is used is because it is stable enough to be transported safely and under the "right" conditions breaks apparts to add more oxygen to then engine. by "right" i mean compression and heat! Trust me when I say it is smarter and probably no more expensive that what you were looking at for the pure 02 idea!

Mint87RX7

i am not necisarily talking about this because i am to cheap to run n2o, i was just curious as to whether or not it would work. Just seeing the oppinions of others

In Theroy under the right conditions... Yes it would work... howerver there are soo many unknowns... that it would not be as safe!

Mint87RX7

i think my real concern is that if it did ignite in the intake i think the flame could travel through the O2 line since its full of oxygen and blow the tank, thats why i was thinking of having a tank with a slightly higher O2 enrichment than normal air but enough to increase the intake O2 by 5%

ilike2eatricers

You would need a one way check valve.

Right now I'm taking a welding class and doing oxy acetalyne cutting. Oxygen itself is not flammable that is why we must turn on the acetalyne first and ignite then add the oxygen. The oxygen tank itself is under very high pressure and could explode if too much vibration occurs or it is struck.

EDIT: Should mention it is still possible for the flame to travel up the line but a one way check valve will help to slow it down until it burns throught the valve and onto the bottle.

Ummm... no. Explosions occur during combustion of a material.
N2O does not contain any carbon atoms, and thus cannot combust itself.

Instead, under high heat, it splits into nitrogen and oxygen atoms, two elements found commonly in air. Air in itself is not explosive, so why would nitrous oxide be?


Nitrous bottle "explosions" occur when nitrous oxide gas pressure inside the bottle exceed the safe containment pressures of the bottle. This holds true for any gas, but this does not any gas is explosive...

scathcart

Completely wrong.
The change in gas pressures creates a cooling effect of the air charge according to the ideal gas law.

The nitrogen atoms are for buffering the combustion process so that the mixture does not detonate.

scathcart

It is not flammable at all.

scathcart

It would not work.

O2 tends to burn much faster. The O2 in air aids the combustion cycle but isn't itself able to catch on fire. I'm not sure here, it is just kind of an idea, but I think that when you stick in a bunch of straight O2 in your combustion cycle, it might be possible for the air mixture to actually catch on fire before the fuel sense straight O2 is extremely flamable. NO2 requires massive amounts of heat to break down the compound so I think it is more progressive in it's conversion to release oxygen. It could also just cause the fuel to burn too fast because there is too much oxygen available when it sparks. This is all speculation but it would explain why no one does it/we don't see it. It would cost a bit more too I think.

If anyone knows a scientific reason why this would be wrong, please share it. Don't just say you're wrong if you don't think it's right.
