Some education please
I could use a little education please. This past weekend while munching on some wings at a local bar the discussion of NOS on cars came up. I have never messed with it and I must admit I only have even seen it on a Mopar once. I kind of know the basics of it, but I am not sure of the exact area the power is derived from. Is it the extra flamable material (nitros) that is being injected that burns hotter, or is it the nitros makes the fuel itself burn better? The whole reason it came up is a friend wondered if Hydrogen could replace nitros since Hydrogen is so flamable. To be honest I really dont know much about either element other than Hydrogen isnt something you want to mess around with.

Nitrous itself isn't really flamable. When Nitrous is mixed with the other elements in a engine, it breaks down to form oxygen. And we all know oxygen promotes burning. Basically, nitrous just helps your motor run harder and faster by creating more oxygen inside your motor.

Don't forget that the extra oxygen that comes from the breaking down of the nitrous oxide molecule has to be combined with extra fuel, or you'll get a severely-lean condition and damage your engine very quickly.
There are two major types of nitrous oxide systems on the market, "wet" and "dry". The wet type injects both nitrous oxide and fuel into the airstream, in a pre-measured ratio. The dry type injects only nitrous oxide, relying on the car's fuel injection computer to compensate with extra fuel. The dry type is the least expensive and easiest to install, but is limited as to how much power you can gain, and needs to be used with a computer-controlled fuel-injection system so the necessary extra fuel will be added automatically. Nitrous oxide injection adds power simply by introducing more air/fuel mixture to the combustion chamber than you would normally be able to get in there. Also, the compressed nitrous oxide cools the fuel/air mixture significantly. You've felt an aerosol can get cold when you use it? The compressed nitrous oxide does the same thing when it comes out of the bottle and goes into the nozzle. Scott Gardner |

Good point. A very lean motor would not be good. One thing I think you should have mentioned about the two types of kits is that the dry kits are very unstable and are dangerous. There is risk with nitrous anyways but more so with a dry kit. With a wet kit it is an injection of fuel and nitrous, creating an even combination. Also, this kit can be hooked up to a full throttle switch so that only when it is armed and the throttle is open fully, nitrous will inject. This is much safer than pushing a button controlling the amount of nitrous in your motor hoping that the computer will correctly compensate for the extra oxygen. I've always felt that wet kits are the best way to go and it causes less problems. You really can't overspray causing damage to the motor. It will only inject at a certain point, making sure that the fuel/nitrous mixture is distributed evenly.

Oil spontaneoulsy combusts in the presence of pure oxygen....Imagine the pinging you would get on lots of O and not alot of Fuel. Hydrogen needs O to burn also so the fuel + H would need alot of O and that cant be supported on the intake charge.

Injecting pure oxygen= cutting torch.
