I hope im not getting annoying...

I have a extra AEM intake laying around and got wondering about a few things...

Firt a few questions:

If you mixed: Oxygen (pure) into the air intake would it increase performance or be better for the engine to breathe either PURE oxygen or a mixed ratio of pure and outside air?

I work for a large company in the R&D department of a exotic computer computer and have access to a load of fun toys...


UPDATE:
I drew a picture to help explain.

well if it wont work for oxygen then maybe a nitrous bottle chiller?

thanks

you'd have to recalculate your A/F ratios, among other things...

 

I wouldn't do that if I were you since #1. O2 in a canister is highly explosive if ruptured. and #2 refer to #1. This is the reason why NOS was implemented into cars. Does the same thing overall except the nitrogen acts as a controlling agent so the combustion process doesn't get out of hand.

 

the nitrogen is to cool it, not to "control the combustion" b/c oxygen is NOT flamable, it is a catalyst, b/c fire requires oxygen to burn, but this creates an enourmous amount of heat, therefore the nitrogen is a cooling agent, that is also why turbo cars can use a small shot of nitrous, it cools the intake chrges

 

humm....

humm... if the oxygen idea is a waste then maybe a nitrous bottle chiller??

think about it...

Ok...what a minute here......PURE OXYGEN isnt Flamamble? Ok.......so go get a bottle of oxygen and hold a lighter to the tip and see what happens

The reason that your car runs really good on nitrous is because 78% of the atmosphere is made of Nitrogen & only 21% is made of Oxygen........So instead of sucking in nitrogen and trying to burn nothing.....you are actually adding more air to the mix...More 02....more power

You could use pure oxygen to almost the same affect as NOS....but Oxygen Is highly Flamable

nope, not a chance, what are the three things that fire require?

fuel
space
oxygen

oxygen is a catalyst that cause fire to burn hotter, and acetelene is highly flamamble..... ever filled a container of some sort up with acetelene and lit it? big time explosion.

 

dude...hello....its really dangerous to use pure oxygen.....bottom line

Look at this.....

Oxygen - Specific Gravity - 1.105 - Air 1.0 -
It is heavier than air. It is a violent oxidizer and will explode
when petrochemicals ( oil & grease ) are in contact with pressurized
oxygen.

What part of "explode" is the good part?

fine, i am wrong, whatever dude.... have you ever even used and oxygen/acetelene torch?

one question then..... how come you can't light oxygen alone as it come out of the tank??? you know why, BECAUSE ITS NOT FLAMMABLE!!!!

 

hummm....

I dont see how this would be flamable though...

I my intentions was this:

Not to add oxygen to make it more flammable and combust better.

But rather to add a COLD burst to the intake of "AIR".

and also I figured by using oxygen it would be better for the engine anyways.

also it would be a mix if anyone noticed... of air(from the present intake) and the COLD bust of oxygen...

anyways I guess just a bottle of compressed air would be effective to...
but then it would just be REALLY REALLY COLD AIR. not pure COLD oxygen...

hummm... what ya think?

 

what about using CO2 and spraying it onto the outside of the intake tube?

 

I dont see why you would do that...

why not just do my idea?

anyone? will this add HP or performance?

 

Pure Oxygen by itself is not flammable (it is combustable), supposedly you could light a spark in a jar of pure oxygen and it wont ignite.

Compressed oxygen is classified as hazard class 2.2 non-flammable gas. I work with and around Haz-Mat so I have access to the literature. HOWEVER I would still treat oxygen as flammable (even though it is not), because once you mix it with fuel in your engine THEN it becomes highly flammable, and it is hard to predict the properties of PURE OXYGEN in a motor.

Did you happen to factor in what happens when the oxygen reaches the combustion chamber and is ignited along with the rest of the air and fuel?

I said oxygen BY ITSELF is not flammable, but once you add fuel it becomes flammable (actually it's highly combustible). The fuel will be ignited by the spark, but the extra oxygen will be ignited as well. And since you probably wont be increasing your fuel delivery, you could possibly end up with a very very very very very lean condition.

thank you shadow, that was exaclty what i was trying to say, that oxygen alone is not flammable....

 

How come when I read this rotary engines keep coming to mind???

 

So what about as JUST a cooling method.

The best way to cool anything is to cool from the inside of the object heating.
So how about ditching the oxygen idea and just using compressed air.
when i say compressed air I mean "standard outside air"

By bottling it I can not only compress it for fast burst but also cool it.
by containing you can cool it.

For all those people out there needing some cooling.... this may help?
maybe turn this on when about to run a shot of Nitrous?
maybe run this when about to use higher boost on your turbo?

I would assume when you have a fully modded out car and your about to drag and put your engine through hell for 10-15 seconds it might be nice to give it a nice shot of cooling to go along with all that added HP you just added to your car...?

what ya think?

am I dumb?

 

BTW> they use Nitrous oxide because it not only requires heat, but a good amount of presure to split apart and release the oxygen. Much safer. Oxygen by its self just needs something to bond to and heat. Plus nitrous oxide has a history in engines since the days of WWII (heh as do rotaries)

 

yea drop the whole oxygen thing... im just learning... sorry...

but what about what i just posted? the cooling method?

thanks

Boosted97Lude,

glad I could offer some assistance

on second thought if you held a lighter up to a opened canister of oxygen it probably would explode. I just re-read that you mentioned the word LIGHTER...IIRC most lighters have Butane in them. Butane is classified as Class 2.1 Flammable Gas, so this is pretty similar to what you have going on in the engines combustion chamber.

Gasoline + oxygen + spark = boom
Butane + oxygen + spark = boom
oxygen + SPARK = nothing (hopefully)
gasoline + pure oxygen + spark = big boom and a toasted motor

the key word is SPARK, I said that oxygen introduced to a spark wont explode (hopefully). Boosted97Lude, said FIRE, you said LIGHTER, there is a difference between SPARK, FIRE and a LIGHTER (flames from a lighter).

 

thanks. neat. he understand TRUST ME. he is a smart dude.

anyways how about my quetion i asked?

 

why? what's this got to do with rotary engines?

 

IMO playing with oxygen injection is way way way to risky even if you only planning on using it for cooling purposes. It has the same effect as nitrous but because it has hardly (never?) been tried before you could end up being the guinea pig. You might get away with only injecting very small amounts of oxygen, but you are still driving around with a big tank of compressed oxygen.


And even though pure oxygen is classified as NON-FLAMMABLE GAS it is still pretty volatile and easily combustible, and should be handled with care probably more care than you would with nitrous bottles. You might not know how the oxygen bottles needs to be stored in the car (will it need a bottle warmer?), all that kind of good stuff.

EDIT: and about your compressed air idea, you could get that to work, all you would need is a turbo kit



[Modified by BlueShadow, 8:44 PM 12/23/2002]

 

YES. I understand about the oxygen idea not working. dont waste anymore energy explaing it !!! hehehehe thank though guys... ima noob to cars!

but about the cooling idea... the turbo uses a air intake correct?
So if this lil device was used it would not only cool the engine/turbo
it would actaully gain HP by making the air more dense. which is good for turbos right?

thanks and sorry if im a idiot.

 

Well actually whenever you compress air with the turbo (or through whatever means) you raise it's temperature (make it hotter). The compressed air exits the compressor housing and travels to the intercooler where it is cooled and sent to the intake.

The compressed intake charges temperature right before it passes the TB is normally a hundred degrees (or a few hundred degrees) above the temperature of air outside the car. The more you compress the air (higher boost) the higher the intake temp will be.
