Instead of runnig N20 into the intake (like in a dry nitrous kit) what if i ran in just oxygen. As far as understant the nitrate in N20 is used only as an oxidizer. The reason im asking this is because i'm thinking of buiding a custum kit for my car, but instead of running a 10 pound tank of nitrous, use a small oxygen canister. I know that just oxygen wouldn't provide the same hp gains that you would get from nitrous, but i would like peoples opinions on wwhether or not this would be benificial. Also i know using a custum kit is very risky for the engine, and that i would start out with a very small jet then work my way up. Is this a good idea or am i just stupid?

 

NO!!!!
O2 is flammable, nitrous is not. Oxygen costs more. Nitrous is closer to real air you breath in. There are several more reasons, but I would stay away from that idea. If not, I'll pray for the lives of you and your car.

 

Pure Oxygen is very, very, very corrosive. Rust, alumumum corrosion, are all "oxides" meaning the metal combined with oxygen. in short, Pure oxygen would harm your engine metals.

Also, "perfect" engine air/fuel ratio's are set for 20% or less oxygen. 14.7:1 ratio is set for normal atsopheric air. If you increase that 20% oxygen volume to say 50% oxygen by volume, you now need 30% more fuel, for the same volume of air. (air volume/weight/density) is the same, you just added a higher percentage of oxygen.

Calcuating the proper fuel ammount would be possilble, but it would be significantly higher fuel requirements than just Nitrous.

Oxygen is EXTRENELY powerful flamable catalyst. Things that don't normally burn in our atsophere at 20% oxygen will burn in a say 50% oxygen environment or a 80% oxygen environment if a simple spark is provided. Got forbid you have a intake manifold backfire....

Nitrous Oxide is used because, at normal tempatures, it is perfectly stable. It will not burst into flame or assist anything else in burning. Under the heat and pressure of the combustion chamber, it breaks down into Nitrogen, Oxygen, and many other smaller compounds. Nitrous Oxide has more oxygen by weight/volume than normal air does, but that extra oxygen is introduced at the proper time (compression stroke).

if you could somehow work out a direct oxygen injection system to work with the compression stroke...you might have built the better mousetrap.

Lastly...think of fuel economy and fueling ABILITY. Your fuel system is sized for a 14.7:1 ratio using a 20% oxygen volume. If you start using a 50% oxygen ratio, you are going to need 30% more fuel. You somehow have to have the ability to kick the fuel injectors up 30%...

 

another thing to add... even if you do all that youll probably wont gain much

Reason: Nitrous is FREEZING cold...

Please dont do this... if your still curious about doing it, please post

I would like to show you a picture of my piston


Just so you know what your getting yourself into wink

 

"nitrous is freezing cold" so is compressed O2. i have built a system for my car but been unable to run it. after reading that long post, im questioning if i will or not. i spent almost 2 years working out bugs and designing what i thought to be the best set-up. i dont think corrosion is a big issue as the effects would be minimal. fuel cut would be alarge issue however. the o2 youd be pumping in would do nothing due to lack of fuel. O2 is very very volitile and would be perfect to use when you first think about it, but now that i actually heard some arguments against it, im thinking about scrapping the system and buying a venom 400 or nx express (35,50,75hp system)the car i was first going to test it on was a turbo awd talon, but that died, and fo a while so did my plans on this o2 invection system. think of it this way itd be like running a 1000hp shot of no2 on a 1.6l honda engine. there is virtually no way to figure out how much hp youd be getting from a shot. you could run it at 10psi or 50psi and have no clue what would happen. odds are youd fry your intake manfold after about 3 seconds at even 10psi because the o2 would synergistically ignite everything and expand well beyond the t-body, fry the filter and youd probaly burn up your piston rings and "poke" some holes in each one of your cylinder walls.

good luck i think ill just buy a $500 kit and save my self 2000$ for a new engine and 5000$ in burn treatment at the hospital.
have fun

another reason why pure o2 isn't used, is that if you provided enough fuel to run the pure o2, you're engine (block and internals) couldn't handle the power. the nitrogen cushions the combustion. what random said is true, but what i just said is also true.

 

Yep, pure oxygen would run hotter in the chamber, not as much inerts to soak the heat.

Bad news all around. It could work great in an engine designed from the ground up to run enriched O2. Unfortunately, there aren't many of those around.

 

Well you cant use o2 because, if you notice o2 isnt in Nitrous. Its 2 nitrious 1 oxygen (n2o)...dinitrous-oxide (chem sp?). Its not the o2 that we breathe.

What happens is when you spray the N20, the 2 parts nitrous separates from the O, and dissolves into nothing and the 0 is whats left to burn in the combustion chamber.

 

well you'll never get pure oxyegn! i don't care who you think you know. The purest oxygen is avator's oxygen and it's 99.5% pure. The air you breath at sea leval is 78%nitrogen 21% oxygen. Just thought i'd throw that in.

 

Doesn't really matter if it is the oxygen atom (O) or oxygen molecule (02) that is in the combustion chamber. Both support combustion. Just because there isn't an oxygen molecule in the nitrous oxide formula doesn't mean that oxygen molecues don't aid combustion. What do you think gets sucked in through your intake?

In an engine with direct cylinder injection, engines that can run without detonation at a/f ratios up to 60:1, it could conceivebly work. Since none of us have those motors, forget about that. The increased corrosion over time would be a problem, but for pure race engines it might work. Maybe, with enough research, it could be used. Just be ready to spend half a million dollars doing r&d for the next ten years. Let us know how it goes after that and I may just be in line to buy your product. wink

Oh yeah, WS6, there aren't two nitrous atoms in nitrous, there are two nitrogen atoms and one oxygen atom for each nitrous molecule. Chemistry nomenclature can be confusing though. Also, whoever told you that the nitrogen dissolves into nothing obviously hasn't heard of conservation of matter. The nitrogen eventually forms molecules and is exhaled by your engine to the atmosphere. It also performs other activities in the combustion chamber, but that is more physics and a lesson for another day. One more chemistry thing though, put your cats back in, those chemicals are bad stuff that I don't want my car to suck in.
