I'm cursed with an engineer's mindset, so I'm always thinking too much. One thing that always bothers me - why don't car's use pure oxygen injection instead of using atmoshperic air?

I mean, after all - gasoline only needs oxygen to ignite. And air is only ~70% oxygen. The other gases, mainly nitrogen, just take up space, right?

And you could use pressurized tanks to create boost.

Feel free to flame me if I'm making a fool of myself.

 

it would be cool to see a set of those little clear nose hoses hooked up to your old *** tired engine's intake mani....just kidding. dont know sounds like it may help induce detonation though with the air being 100% oxygen.

 

im not a chemist but i think pure oxygen is too volatile when mixed with fuel. besides, if it worked it would have been done a loooong time ago.

 

well, not to many people were allowed to work on their cars after inprocessing into the retirement homes

 

If you did that you would blow the **** out of your car. You would be indeed cause detonation. And atmospheric air is only 30% oxygen and nitrous is like 40 or something anyhting else would blow your shiat up.

 

you will melt your engine... trust me.

air is ~24% oxygen, and nitrous is ~33%


100% would be pretty dangerous. You bet your *** i wouldnt be driving around with pure oxygen in my trunk.

This is the correct reason we don't do it. The fact that if your car was on fire, your oxygen tank would make it sooooooooo bad... that, and the fact that it costs a shitload.

Pure Oxygen would use your pistons as fuel.

 

Well actually...

1. Chemical composition of air = 78.084% Nitrogen and 20.9476% Oxygen.

2. Bottled oxygen is WAY cheaper than race gas.

3. What exactly are the dangers of oxygen tanks? It's not like oxygen is flammable. I mean after all, there are street cars with hydrogen tanks in them. Now THAT is dangerous.

 

the triangle of chaos......oxygen, fuel, heat. you need all three to start a fire...gas, mechanical friction, and pure oxygen...doesnt sound good. but give a shot and let us know what happens better yet light a match and throw it in a jar...then light a match and throw it in a jar with pure oxygen feed it...

 

pure oxygen will not work. why?

-it burns too fast and too hot. thats why nitrous xide is used. the nitrogen slows the burn rate to a more useable speed/temp.

pure oxygen uses ANYTHING for fuel. open a bottle and spray it at a puddle of oil/grease and it will ignite.

so no oxygen for you.

 

you might as well use C4 as fuel oxygen&gt;you

is there anything more combustable than oxygen?

nah, nitro-glycerin works way better. its a liquid

Huh? But oxygen is not combustable... It's not flammable and it doesn't burn by itself. And throwing a match in a jar of oxygen just makes the match burn faster. All oxygen does is allow things to ignite and burn, but that's kind of the point of a internal combustion engine right? .


Although I remember someone telling me once that nitrogen in the combustion chamber is good because it helps the fuel and oxygen mix. Not sure how though...

 

To burn is to oxidize. Recognize the oxygen content in the air as an efficiency of the gasoline. By running pure oxygen, the gasoline will burn 5 times faster and more energy(heat)^5. If you ignited at top dead center, each rod would be launched out of the car instantaneously. Half of us won't touch nitrous, and that is a small improvement (Nitrous ~34%, Oxygen about 19.4%).

 

I explained the triangle to you....oxygen, heat, fuel....add more oxygen to the triangle and you need less of the other elements....i.e. 100%oxygen wouldnt need hardly any heat (friction,mechanical type) and literaly no fuel....

 

what about propane? I know the deisel guys are doing it and they have been expirementing with fi gasoline cars but i havent heard too much about it.

 

propane injection slightly cools down the engine, and slightly increases the octane.

 

What about CO2 injection?

 

c02 is not combustable...

Neither is oxygen, air, or nitrous oxide...


I found the answer to my question anyway. CO2 kits (I was thinking about cryo2 when I asked the question) are only used to cool down turbo components. CO2 is actually a fire suppressant. .

what he was trying to say was that c02 will not help combustion. air is needed in combustion. nitrous increases combustion, and oxygen will sky rocket combustion. c02 wont.

 

if you need more power add more nitrous oxide+more fuel. safest way.

Nitrous oxide is useful because during compression, the extreme heat and pressure breaks it down into N2 and O2. The freed up O2 molecules facilitate combustion.

CO2 does the same, except it has a higher concentration of O2. But I guess nobody wants carbon taking up space in the combustion chamber.
