Here's an idea...oxygen injection....

I may have posted this once before, but if not, here goes...I was thinkin, why not inject some pure oxygen into the air intake in a car? The O2 sensor should pick up leanness, and as a result the computer would compensate for the lean factor by richening fuel mixture, so so more fuel = more power. Plus, pressurized oxygen is cold, so it'll cool the intake as well. Waddaya guys think?

I believe O2 is too dangerous to do that with.

bottled o2? Hell yes...can u say boom. If the valve leaks, the valve can potentially make a spark and with that much compressed o2 ud have a nice lil driving fireball. Too dangerous, not to mention illegal

Actually, O2 doesn't explode...but it makes any other accelerant burn like hell. O2 is what welders add to cut metal.

Given what adding 02 does when welders cut metal, my guess would be melted/burnt pistons/valves, at a minimum.

BTW, the O2 sensor only compensates at part throttle...and only within a range. If you go "out-of-bounds" you would get an SES code. And for WOT, melted pistons (again).

uhhh pure oxygen is one of the most explosive gasses used today. thats why the space shuttle uses it to launch and move in space. Liquid Ox is even more dangerous.
Now ox injection could work but the computer can only adjust so far... Yes it will keep the injectors open longer but after a while it WILL pop a code.

What you are suggesting is basically a low pressure boost system.

No, actually compressed air CAN explode. If the right elements were there, it would.

Actually when you run Nitros, youre adding extra Oxygen and in turn you can burn more fuel. The Nitrogen molecules act like stabilizing agent, a buffer if you will. Just imagine, the air we breathe is mostly Nitrogen w/about 9-10 percent Oxygen.We, humans can't breathe pure Oxygen. Same applies to your motor, in a manner of speaking.

compressed air needs a fuel....pure ox is the fuel with the oxidizer...it just needs spark. Just like 100 percent pure water CANNOT cunduct electicity..beleive it or not go see...its all the impurities that conduct the electricity, same goes for atmospheric oxygen. The "air" we breathe is non explosive, it is mearly an oxidizing source but is not a stand alone fuel. So it still needs 2 more of the elements of the fire, a true "fuel" and spark. Pure ox is a fuel and an oxidizing source, all it needs is spark. Any spark and it goes into a very big BOOM!!!!


The welding torches ox is explosive because it is PURE ox. Now the acetilene is beside the point as being explosive.

Nitros is a freezing agent used to condense the incoming air. It boosts the intake charge density, and has "fuel" source of its own(nitrogen) that helps the added fuel mix better to make an even more dense intake charge.
We all know that cold is more dense right?. Thats how nitro works it make the air dense inherantly forcing more air into the intake.

Camaro...Pure O2 is NOT a fuel...it IS an oxydizing agent. In fact, that is where the word "oxydizing" comes from. Take a lit match or cigarette and put it in a jar of pure O2 and it DOES NOT explode...it burns VERY BRIGHTLY and rapidly; but does not explode.

The reason is because the ONLY FUEL is the match or the cigarette itself. Do the same with Hydrogen and it goes ka-boom. This is because Hydrogen is the fuel and air is the oxydizing agent.

If it did explode, then when a welder hit the O2 on his blow torch, it would explode instead of doing what it really does; burns the metal when the metal has been sufficiently heated. The "fuel" is the metal itself.

Ask a Chemistry teacher if you do not believe me. I did this back in Chemistry when I assisted to demonstrate what "oxydizing" agent meant and the differences of various gases. FYI, Chlorine gas and Florine gas are also "oxydizing" agents.

As for NO, it both frees up the Oxygen molecule for the reaction and cools down the charge of the intake allowing for a denser charge. NO is not a stable gas and readily gives up the Oxygen molecule for the reaction.

That is why people don't die from aphyixiation, but feel light headed when they breathe it. NO2 is the more stable compound. I've heard 40/60 between the split for where the power from using NO comes from (40% - Freed Oxygen molecule and 60% - cooling effect).

Regardless, using pure O2 in place of NO is definitely not recommended. It would make the gasoline/O2 mixture is too reactive and would result in melted/burned the pistons/valves in the engine.

You are right about the Nitrogen acting as a "buffer", though it too can react to an extent. The EGR gives an even better "buffer" because it cannot react much more (other than to reburn more completely).

But the actual percentabe of O2 in the air is 19-20% IIRC. Just under 80% for N2 and the rest is all the other gases. But, in a few years, maybe your ratios will be more correct.

But, YES they do give people pure O2. It is VERY breatheable for humans. Extra O2 is often given in medical situations because it is easier for the patient and tends to calm them too.

Oxygen IS NOT EXPLOSIVE..... It supposrts combustion.. I used to play with LoX (liguid oxygen) in the service. We would load it onto jets and such. We also took a bullfrog once and dipped it into the LoX.. We then threw it at a wall - it shattered like glass. VERY dangerious to play with, ya need special containment, licenses and handling to even buy it.

Good idea but NOS is better

Right... Pure O2 won't explode... But, compress it, and it will. Well, not technically.
Technically, it just burns so hot and fast it expands to beyond the limits of the container, and the container explodes in a fireball. I think that's what he was talking about in the first place.

Well put and I agree with you except that we humans can breathe pure Oxygen. Think about it Hospitals put you on tanks that have pure oxygen in them, though these are low pressure tanks and are not exposed to the abuse of sitting in a car. I was reading this post wondering when someone would actuall say that Nitrous is how you inject O2 into the engine and the Nitrogen is the stabilizing agent.

Uhh.. just to put a cap on the O2 explosive or not debate.. we had a truck here carrying medical compressed O2 canisters a few year back.. well, the driver looked out his rearview one day and noticed one of the canisters was on fire. He was at a stop sign fortunatly, and jumped out of the vehicle and ran like hell (I say he was fortunatly at a stop because I figure he would have jumped even if it was moving).. 10 seconds later, and explosion rocked the whole friggin town.. I *FELT* it 5 miles away.. looked outside and saw the fireball (was kinda cool really). Anyway.. roofs ripped off, windows shattered up to 3 blocks away, etc.. it qualifies as explosive when compressed. So if you really want to run compressed O2, have fun.. but don't yell at us for not warning you when we meet again in the next world.

Ever been to a hospital with a huge *** 02 tank outside and seen all the signs NO SMOKING DANGER and the brick wall and or fence around the mother, uh yeah i'd say it's explosive. As for the danger part, anyone seen the aftermath of a nitrous bottle explosion? tell me that ain't dangerous too, it's all dangerous if you don't handle it right or if your equipment is crap.

Auxout, isn't that the car of the guy that left his bottle heater on for a few hours, and the bottle exploded? Yeah, it is... people try to say "nitrous is dangerous", but they don't know the story.

The guy had a NX nitrous system (not NOS, but, doesn't matter anyway) in his car. He had a bottle warmer on it, and left the toggle switch on in his garage. It was wired to the battery, so the warmer could be on when the car was off! He forgot about his toggle switch and the bottle overheated and exploded. That guy should've had the bottle warmer wired so it was "on" only with ignition, not on all the time.

The website is now pretty much crap, I guess NX made them remove everything. Here's one part of what's left- the guy's "statement" on what happened. http://www.enhancedhealth.com/statement.htm

I feel bad for him and all, and I'm glad nobody was hurt, and I see his argument, but still- that bottle warmer was wired wrong.

Well as I stated before O2 is explosive as have been confirmed by a few peps here... But OX injection is as I said before a low pressure boost system.

Well a couple of things here, TomP All I said was anything is dangerous if you handle it wrong or your equipment is crap, I didn't mean nobody should run nitrous. But would you run nitrous with a homemade nitrous kit? I think not. About the bottle warmer being wired wrong, that isn't what caused it to explode, my understanding was the bottle should have never exploded because they had a blow-down tube installed. Also how did you get it was wired wrong from that article?

[EDIT]
Oh I see what you mean about the switch being able to be on when the car was off, that's dumb. However that is no reason for a bottle to explode, the equipment didn't work right.

Well, Karl, from the response here, I'd probably want to stay away from using it extensively. Not to say I'm gonna avoid it, though...maybe inject a small amount into the air stream to see the effects...I'm not gonna go for something like a "50 hp shot" or anything. My rationale is as follows: Drive a car at high altitude, and there is less 02 so your car compensates. Drive at low altitude, there is more 02, so your car compensates. Add a bit of 02, and your car will compensate, within reason. I think having an "open/cloosed loop" light will also be useful in determining when to apply 02. But my car runs waaay rich at WOT, so even then a bit more 02 shouldn't hurt...and I'm at a slightly higher altiude, so got a bit more leeway there, also....I'll decide in the next few days, maybe....

Sorry if I wasn't clear; I knew you never said "nobody should run nitrous". I was just saying that most people who do say "nitrous = dangerous" refer to that explosion.

Uh I have seen many a motor blow using nitro. I have even seen a high dollor(6 grand) 383 stroker blow apart. The thing sheared the head bolts along as turn that pretty stroker crank into 6 different pieces. It seems he forgot to hook up a handy dandy supplied RPM electrical switch. It seems it was a dual stage 200/350 setup that kicked the 350 in at 2800RPM...Can you say KABLEWIE!!!! Me personally am VERY wearing about using NOS...
