Flame if you wish but not too hard..ok the engine burns oxygen not fuel right so what if you were to use a bottle of pure oxygen (from AGA or medical supply co.) and run it just before the TB like N20? Usin tubing and letting the TB suck it in? Is Oxy too flamable or unstable to use or cause too much heat in the engine ? Not going to try..but is it possible?

 

It's way too powerful/explosive. Pure oxygen is a HAZMAT and can't be carried on a vehicle (without a permit). I think maybe some type of top fuel dragsters might do something like this.

When you use nitrous, the nitrogen and oxygen seperate and the nitrogen acts as a buffer.

 

Well, I'm not entirely sure how naaaaaaaaws increases horsepower, but I think part of it is because it reduces combustion temperatures (please correct me if I'm wrong).
But if that's the case, then it MIGHT work, cos I think it's compressed, which means it'd be cold when it was released from the tank.
BUT, would it lean out the mixture too much?
That's just my thinking, but this is better left to the experts....

 

ok so the nitrogen keeps it from being too powerful and calms the explosion a little?

 

The inert materials in the air do act to soak up a lot of heat and remove it from the cylinder. Nitrous oxide carries some extra oxygen in, it only increases the burnable oxygen content in the air by a few percent unless you're running some crazy-huge shot--but it provides a decent power increase due to the increased oxygen and the cooling effect of spraying. And besides all the dangers of running a pure oxygen system, it would be hellishly expensive to pump both petrol and O2 at the filling station. EDIT: I just poked around and apparently the price of oxygen as a refill is cheaper than nitrous. It still would be quite expensive to run it as a constant injection though.

The inerts provide another important function on the inlet side--they help to carry the atomized fuel. The flow of pure oxygen necessary to achieve combustion is a lot lower than necessary to maintain the misted state of the fuel. Without the proper intake velocities, the fuel would drip out and you'd end up with puddles of liquid in the cylinder that wouldn't burn.

I really wouldn't recommend an oxygen injection system. It holds huge potential for intake manifold backfires and will cause fuel to burn explosively at atmospheric pressure. I'd rather go with something safer, like a 500-shot of nitrous.

Oh, and air horns don't burn anything--they just blow air at high speed through an orifice or past a reed (thin plate that vibrates) to create sound.

 

As a side note some top fuel Dragsters also use Propane.. Course those are million dollar cars..

I would love to see a million dollar tibby. (with that said I know some geek is gonna make an add for a million dollar tibby)

 

Propane injection is a relatively common setup on diesel engines. Recently there have been people experimenting with propane injection on Supras and stuff.

Electric Head: Yea basically thats how it works.

 

If your gas tank was hit in a wreck and ruptured and exploded, you might have a good chance of living through it.

I think a lot of us saw what happened when the maxima's N2O heater stayed on too long and the bottle popped...and that was just the pressure.

O2 will explode anyhow, N2O at least needs to be HOT to burn. If an O2 cylinder ruptures and burns, you wouldn't even know how you died.

Nevermind the very large amounts required would be pretty expensive compared to gas on a constant feed. If you mean like on a N2O setup but with O2, then it may work. But don't forget...Oxygen is highly reactive, and heat and dirt make the reactions faster... do you REALLY think it's worth the risk of rusting (corroding) your intake and cylinder head bits, plus maybe the cylinder walls, just for more power?

All the same, it's an Excellent Question. wink

$0.02.

 

Yeah, you don't wanna inject pure O2 ito your car. I mean even the human body cannot handle inhalation of pure O2 normally(unless in emergency situations.) It drastically increases metabolism and it's not good for you. Same to your car.

 

Pure O2 is very corrosive. It causes oxidation (rust) on any iron surfaces in a very short time. Ditto for aluminum, and nearly any metal.

The part about Nitrous Oxide that makes it workable is that for a given volume of Nitrous, they know exactly how much Oxygen is in there, and thus how much fuel to add.

If you were to run an oxgen setup, you would have to meter the oxygen as closely as you meter the Nitrous, even more so really. As a small increase in oxygen can cause you to run lean/detonate.

Also, Nitrous Oxide does not break down into Oxygen and Nitrogen until the heat/pressure of the combustion chamber. Injecting straight oxygen would allow a backfire into the intake manifold, or preigition in the combustion chamber as soon as the pure 02 entered.

Pure 02 is VERY voltile. VERY.

It sounds good *in theory*, but in practice, it is so hard to do right, Nitrous is the easier/cheaper solution.

Nitrous Oxide is also cheaper per # than Pure O2 per #.
