Basically, when you shoot N2O, the idea is that you burn the gas releasing 2 Nitrogen atoms and 1 Oxygen, which then allows more fuel to burn. Is there a reason for the Nitrogen? Why not just skip the middle man and wet shot O2 into the car?

 

Doesnt the initial breaking of the N2o use energy, Im thinking straight O2 would burn way to hot. This is what i remember reading.

 

ya it would. not to mention o2 is way more explosive than nitros

 

probably for safety.

100% oxygen that comes into contact with any grease whatsoever will combust.

If you are on an airplane and above 41,000 feet and the plane depressurizes, you get 100% O2 on demand (every time you breathe), if you have oil based chapstick on, your lips catch on fire...


and liquid oxygen, talk about freakin dangerous! all tools used on LOX systems must be meticulously cleaned prior, during, and after use. Your entire suit must be meticulously clean, no skin exposed. but it lasts incredibly longer than chemical oxygen sticks (which is what provides oxygen to the passengers in transport aircraft), or pressurized 02 tanks.

 

Yea... oxygen is highly explosive compressed. And the nitrogen cushions the shock of the initial burn inside the combustion chamber I believe. Not coincidence that N20 has similar makeup to the air we breathe (Air is what... 75% Nitrogen, 23% oxygen, 2% other stuffs?).

 

Ok, makes sence, thanks guys.





Heh.. the guy who fills my LOX tank at the hospital wears overalls and gloves. That's South Carolina for you.

 

this has actually been discussed a long time ago.... it's dangerous and also I think someone mentioned that straight O2 would cause rust

 

Nitrogen isn't just a bystander in the combustion process because it absorbs heat, reducing combustion temperatures and dampening the combustion process. It turns what would othervise be a violent explosion into a rapid, more controlled burn. Without the presence of nitrogen, the combustion temperatures and pressures would become uncontrollably high, resulting in melted or broken components and we certainly don't want that to happen laugh.gif .

Compressed oxygen is stored at a very high pressure compared to N2O (3000psi for O2 and a 1000psi for N2O). Oxygen is stored in a gaseous form (N2O is stored in a liquid form). The best way to understand the difference between gas and liquid is to imagine that a single cylinder of N2O liquid is the same as having almost 400 cylinders of N2O gas!!! Therefore, a single cylinder of a given size of liquid N2O contains approximately 100 times more oxygen as the same size cylinder of pure oxygen.

So, oxygen is neither a safe nor practical option for the reasons I just mentioned. To flow enough oxygen at the higher pressure it's compressed to, you'd need an enormous, expensive system which would almost certainly destroy your engine cool.gif
