Look, I know nothing. I've never done a mod on a car worth calling one. But I've been reading about turbo injection and get the prinicipal: more air allows more gas. Put 'em together in a cylinder=more power.

But it isn't air that allows gasoline to burn. It's the oxygen in the air, which is only 15% or so. Most of air is nitrogen. Such a waste!

What would happen if I just put a tank of oxygen in the car and piped it to the air intake of my engine? Stepping hard on the gas opens the o2 feed. Engine gets a heavy hit of oxygen.

What would happen? High-G acceleration? Would the ECU be clueless? Would the engine explode? Would it be just waycool?

Since I've never heard of anybody doing this, there's probably a good reason they don't that I haven't thought of.

That's why it intrigues me. It's the more o2 you have in the cylinder that makes it go. Ever had a car above 10000 feet? nuthin'. How about Death Valley? Lots of zoom. It's the amount of o2 in the cylinder that counts, not how it gets there. A supercharger and a turbo do (more of) what you get in Death Valley, higher pressure=more oxygen. But replace the pressure with the proportion of o2 in the gas, you get the same thing without the mechanicals. ---I think.

---and if the idea having 15 gallons of gasoline sitting a few feet behind your butt doesn't curl your hair, I don't why a thick-walled tank of oxygen under the hood should.

O2 is VERY flammible, it will blow up with the smallest spark, some times the spark isn't even visible. plus N20 is useing the same principle

normal air is a 4:1 ratio of Nitrogen to Oxygen, N20 is 2:1 that is double the O2 being thrown into your cyl

maybe you need to read up on nitrous oxide. nitrous oxide works by basically injecting more o2 into your engine, but it is much safer than straight oxygen. if you had any type of a leak you could instantly become a flame ball.:bomb:
did you ever read/hear/see on a movie the apollo rocket that had an explosion on the launch pad? that was caused because they used to use straight o2 for breathing air. on that launch there was a small spark in the capsule, because of the pure o2 it instantly burned up the entire crew in seconds.
liquid o2, when poured on a bag of charcoal, in a bbq, will burn up all the charcoal and the bbq in a couple of seconds. you canfind videos of that on the internet.

basically it is so dangerous that nobody does it.

it's not so much that pure oxygen is that dangerous in of itself. it needs fuel to cause a flame, but pure oxygen will cause anything to burn. that's where the harm is. with nitrous oxide, the nitrogen acts as a carrier agent for the oxygen, and makes it more stable for use in certain applications where you need more oxygen.

NO!NO!NO!NO!NO!NO!NO!NO!NO!NO!NO!NO!NO!NO!NO!
OXYGEN IS NOT FLAMMABLE!!!!!!!!!!!!!

Oxygen supports combustion. If you take something that is normally non-flammable, put it in a chamber with pure oxygen, it becomes flammable. That is the danger of pure oxygen. It's not flammable.

Hydrogen is flammable. See Hindenberg.

pr5owner and Tom Slick are right about nitrous oxide. Nitrous oxide does exactly what you want.
Taken from here.

Oxygen is just a reactant, by itself it is harmless. I've seen videos where holes were made in a concrete slab using a combination of liquid O2 and a simple flame source.

Fire is a self sustaining reation of the fire tetrahedon producing byproducts of heat, light and gassed (smoke etc.)
The tetrahedon is the combination of oxygen, heat, fuel combined by a chemical chain reation.

Oxygen is a needed component of combustion. Atmoispheric % is 21%. There is such a thing as too much of a good thing- it must mix with "air" to reach its lel (lower explosive limit) and uel (upper explosive limit). Basically lean to rich.

The moral of the story is please dont hook up pure oxygen to your car in my fire district, I would hate to have the corriner ID you body via dental records.

(Yes it would work, as long as you did not make th eo2 too "rich-
god help you)

Thanks to all. It was a thought experiment...I knew nobody did this for real good reasons. Now I've got the reasons. I promise not to try; I like to have my teeth inside an identifiable head. Anybody ever try a slow drip of nitro-glycerin into their cylinders?

Just to add my .02 into this discussion, I believe that direct injection of anything more than a minimal amount of pure oxygen would cause your engine internals to melt or atlest you would probably burn holes in your pistons valves, or make the engine overheat so much that it would sieze or otherwise. because as we all know, in a fire, more o2=more heat.

Yes, I for got that. you would die, but that is not the worst part-
your engine will break. (next of kin can check your warranty)

n2o Is soo much more fun anyways cause if your car is still slow after you shoot it then you can sniff it and laugh yourself to death.

"Dont siff it as you could die from it"

01ProES

You can't. They have this stinking stuff in it to make it very unpleaant.

mito7878

I know!!! It was a JOKE... But it seems that you may have tried this?
