Nitrous oxide (N O) is a
2 chemical compound of nitrogen and oxygen that can be stored in liquid form when it is under pressure and at room temperature it is a stable and non-flammable gas. However, when it is subjected to heat and pressure it splits down into its component elements of nitrogen and oxygen, and that’s when the fun starts. When nitrous oxide is injected into an engine’s combustion chamber it breaks down and the release of the oxygen allows the fuel within the chamber to burn more efficiently, producing more power and allowing more fuel to be burnt, further increasing the motor’s performance. In addition, the vaporization of the nitrous oxide liquid has a cooling effect, again improving combustion by increasing the density of the air within the chamber for a better burn. There are downsides as the sudden power boost puts massive strain on an engine and NOS can only be stored in relatively small amounts. Also, NOS systems fitted to cars can lead to terrible films and even worse paint schemes!
