A&Q about 350Z
Q:
Umm... Boyle's law states that n1 X sinx1 = n2 X sinx2
A:
p1v1=p2v2
Pressure times temp is equal to pressure times temp....
A:
volume* sorry. Pressure times volume equals presure times volume.
A:
oh ya, and you arent the first person to think of this on this form and i would like a patent number also so i can go look at some schematics....
and im still not ocmpletely understanding why you need liquid nitrogen.....when you spray the stuff and the compressed air decreses in pressure it will automatically become very cold.... like an areosal can... when pressure is released things get cooler....
A:
His plan is to have a pipe inside of a container, and pump that container full of liquid nitrogen. Then, using an air compressor, pump air through that pipe, which will turn into liquid oxygen, which can then be injected into the combustion chamber.
I'm not saying it would work or anything, thats just what I understand as his idea.
A:
got it now... originally i thought he was running a coil in the intake. his explinations are very unclear. so basically you are just spraying cold air into the intake? well it isnt going to be liquid, just very cold. you may eventually see 3-5% increases (just taking a wild geuss)
let me post some schematics so anyone who doesnt understand now can understand.
A:
basicly frozen water and cold air is about all you gonna get....id just pour hte Ln2 in the intake manifold that will get you somewhere.
A:
I'm not sure if its right, thats just how I understood it :P
And yes, I personally would not use it in my car, but if he wants to try, I guess.
A:
wow i never thought pepole bashing me/my idea would matter that much to me but i guess it does.... so if every one would wait a little i will have the videos up soon. this is pretty much the only way i can prove to you guys i guess. then i expect everyone to say they are soory and tell me they want 8 of them .
A:
An interesting idea, and I would like to see what some real engineers have to say but:
How do you plan to keep the nitrigen in its liquid form for a long period of time?
That requires pressure.
Have you thought about the problem of ice crystals forming?
If your injecting the compressed, liquid air into the intake, and letting it expand, then how is any extra air getting into the combustion chamber?
It needs to remain in a compressed state to over come the limits of the intake, ports, valve, cam and head design if any more air is to be introduced to the combustion chamber.
And, how are you planing on leting the enigne management know more air is apprently entering, and more fuel needs to be added with it?
A:
Have you verified that your apparatus can actually liquify air?
Would it be possible for you to perform a bit of an experiment for me?
1. Determine the mass of the empty nitrous bottle.
2. Determine the volume of the nitrous bottle.
3. Run the apparatus and compress the air into the bottle.
4. Determine the new mass of the bottle.
I would be interested in knowing the density of the air compressed by your apparatus.
A:
people arent bashing you. You asked for their input and they are giving it to you. All it looks like your doing is trying to inject cold air into the intake. I dont think anyone is doubting that you can make some power with this, just not enough to justify doing it. Also if the air is as cold as you say, how are you going to prevent water molecules in the air from freezing into ice crystals? Or freezing the gas? Did you ever think of what kind of shock that would put on the internals of the engine? Extremly hot to extremly cold? Over and over again? your gonna start cracking the engine apart.
Here i got a little experiment for you to do. Take a metal spoon and put it in your freezer for an hour or so, untill its just as cold as the freezer. Then add some sugar and water in a glass. Mix it up good, and microwave the sugar water for about 5 mins or untill it beings to boil. Now with some safety gear as in eye goggles, gloves, so that none of your skin is exposed. Take the cold spoon and put it in the glass. The resulting effect should be a semi violent explosion.
A:
The way I understand it, is:
1. Submerge a copper coil into Liquid Nitrogen.
2. Force air through the coil via a compressor @ 50-100psi.
3. Store resulting liquid in an N2O bottle.
4. Run liquid AIR through engine as one would use N2O. As liquid air moves through lines, it warms up to its gaseous state which is still WELL below atmospheric temperatures resulting in power gains.
As he said, tuning has not been done. With a larger shot of air and some a/f tuning, I'm sure this design could turn out some great numbers. The only thing I am questionable about it storing this liquid air at atmopheric temperatures. Would it not eventually explode, or does it act just like CO2, the pressure at this point forces it to stay liquid and cold?
Moxion, let me know if I understood your design correctly, or if I'm way out in left field.
A:
That IS something you'd wanna do. Get a compressor that is used for SCUBA tanks, or the like, so it removes the moisture from the air, so you don't end up with iced lines.
A:
ok folks once AGAIN there is no nitrous bottle involved !!! and please dont post retarted experimants for me to try im not fresh out of school i have a very good idea of what im doing. at least i should ive been workingon this for 2 years.
now to answer some questions
MOPPIE i would love to talk to a real engginerr. if you know any that would like to do some freelance work let me know. as far as your questions go we shot this into a car remeber? no gas froze and it showed hp gains. so my guess would be it makes it to the cylinders still in a compressed state. we are currntly working on a pressurized nitrogen bottle for longer storage but it hard to find a company that will let me put a copper coil in thier containers and still pass saftey test. but i can tell you that 45 liters of liquid nitrogen last almost a month in a open atmospher dewar so its not a top priorty right now. as far as engine mang. we have looked into apexi sfac for right now. our first test we ran in front of the maf caused the computer to overcompasate, the computer just wasnt fast enough and we got really bad air/fuel spikes all across the dyno run. and finally the ice crystals.. finally some one bought up one of the problems were having instead of ones we already solved!! we have found that if you use the coil about once a day the coil dosent frezze up much but if you let it sit the coil becomes cloged.. no real solution in site except mabye a purge or hot wire... any one have any ideas??
sluttypaton- the experiment commet was not for you.. yes we have veirfied that this does liquifie air if fact one of the videos i will be posting show us filling half a gatorade bottle and puting a cigaratte in it ( burns completly down in about 30 sec really cool) as far as density i dont have a clue nor the supplies to test. the closest i could give you would be to look up the density for liquid oxygen and then minus like 20 ( not very accurate i know) thats the only thing i can think of.
