i was just wondering what if you ran oxygen in to your intake. pure oxygen, what would that do to an engine good, bad? when it comes out of the bottel it is fairly cold. has any one ever thought of this and or done it? doing thins in theory would help wouldn't it? what are all of your thoughts about this?

 

I think its because O2 is flamable whereas NO2 has to reach a certain temperature so that it breaks down to O2 and N. O2 may ignite on its own too early possible in the intake if it's not injected direct port. just an idea hope to hear more on it tho it could be done i think.

 

thanks for the feed back anyone else?

 

That's pretty much why straight O2 isn't used. I think there are some other problems too, such as storage maybe?

 

yeah they pretty much hit the nail on the head, when it comes to stuff like this i just think :

im sure someone else has thought of it a long time ago, and there is a reason why its not done.

 

ok

 

OMGGG!!!!!!!!!!

 

Ok, oxygen is an oxidizer. Oxygen does not burn (it's not fuel, remember, fuel, oxygen, heat = combustioin). Oxygen is VERY VERY VERY VERY violent if used incorrectly. Your engine would explode almost instantly if you shot a good bit of 02 in there. Think about it, the air your car "inhales" is ~~ 20% oxygen. Nitrous oxide has more nitrogen than oxygen, it kinna buffers the extra explosive forces of the new oxygen molicule.
With straight oxygen, the explosion forces would be TREMENDOUS! Adding some oxygen should not be done( my .02 cents). It has no buffer agent and is too violent.

 

the O2 molecules provide the extra oxygen for more combustion while the nitrogen protects the engine from detonation by acting almost like padding if you will, in the combustion chamber. keep in mind that air is roughly 80% nitrogen which does this anyways. Id imagine straight oxygen would either blow up your motor or greatly reduce the life of it. Also, as mentioned about O2 being cold upon release, any gas is to a certain extent when it's pressure is decreased (hence why pneumatic tools are cold after running them for a while)

 

damn i gotta learn how to type faster :P

nowhere, that's exactely what I was trying to say

 

CO2 better for cooling ?

 

What if you add a tinny amount into intake box to increase oxgen level from ~20% to about ~35%? I don't think would cause damage since its not stairt 02 going into the engine. Don't know what kind of gain one would expect though.

 

Just adding O2 on its own would never, ever produce any power and do anything other then blow your car up. What you'd need is a "Wet" system that injected more fuel with it.

First off, you guys pretty much had it right with the "Its not safe" bit. Storage and operation is phenominally unsafe. I wouldnt store this stuff anywhere neer your gas tank (You're also probably by federal law not to carry it w/o the proper green sticker on the side of your car)

Second off, a very, very small amount of O2 w/ fuel would make a HUGE difference! Almost too much power! And its not easy to meter it out correctly, as well as the fact you'll need a LOT more fuel to burn with the 02.

Third off, think about this, a kind of solid state rocket fuel is O2 injected to Aluminum! Yeh, thats right, your engine would use itself as fuel!! (Probably only in a lean condition, remember, turbulance!)

Fourth off, raising the % of pure O2 is very, very very very likely to cause your engine to start outright detonating. O2 doesnt EXACTLY make things more 'volitile', but its the best way to think of it simplistically

 

Also, if O2 comes into contact with grease or oil it reacts violently.

ok so what if you could do it in a little amount so that it just increased the o2 % and you added more fuel to compensate for the increased oxygen. say on a turboed car durring boost. wouldnt that let you increase the about of fuel that you could burn and in turn make more power.

 

Hhaha, use it, make sure to stand FAAAAR away and get it on camera, might want to call the news and fire dept. too

 

Your idea here as everyone has stated before is a pretty good one. In fact a few decades ago NASA looked into powering engines using pure oxygen and a spark plug... They basically got rockets. Current Space shuttle engines drive on liquid oxygen and a lithium charge, all of which combined has enough explosive force to level long island if I'm right.
So good idea, wrong vehicle

 

The space shuttle uses liquid oxygen as one of its fuels, it has 37 million horse power.

Hmmmm...

37 million horse power, 1.3 litres, interesting..

 

Another rambeling.

0 to 17,000 miles per hour in only 8 minutes.

 

Nitrous dioxide is an unstable molecule that is never injected into engines.

Nitrous Oxide, or N2O, breaks down into 2 nitrogen atoms and a single oxygen atom when heated.

 

How would you meter this? The volume of oxygen entering the engine (as a function of time) increases as engine rpm increases. Via direct injection of oxygen, such as is used with nitrous kits, there is no variation with rpm; you inject a set amount of the gas (not gasoline).
As well, due to the MAF systems of FCS and MAP systems of most aftermarket EMS being calibrated for the 21% standard oxygen percentage in air, there would be no way for the system to recognize the extra oxygen and add the correct amount of fuel.

 

Nitrogen, as present in air and in Nitrous Oxide, acts as a buffer to the combustion of iso-octane, C8H18, and physically slows the speed of the combustion. Internal combustion is relatively slow as the explosion is intended to "push" the rotor/piston, and not destroy it.

Addition of any straight oxygen to the standard conditions of an engine will cause immediate damage from detonation: the explosion will be far too violent to do any force to drive the engine, and instead bounce around in the combustion chamber, destroying the seals.

The addition of Nitrous Oxide is dangerous enough as it is, requiring slower burning (high octane) fuel and retarded ignition timing to prevent the engine from grenading.

Straight oxygen should NEVER be injected.

 

dumb idea. if the o2 doesn't ignite before it reaches the chamber, it seems to me that it would make it run really lean, bye bye motor.

 

I want to see someone try injecting fluorine gas (F2) into their engine. You can burn anything in fluorine... Whose got an engine they want to donate to science ?? :P

 

Here's another thing to think about:
Remember what happened to Apollo 1? Thats what happens when you ignite pure oxygen. A massive, all-encompassing fireball.
