Nitrous oxide gas is happy or popular name for nitrous oxide gas. This is the effect it has on people who inhale. Calm and dreamy let them out and will be marked by hysterical laughter. The gas has a chemical formula N2O and is characterized by an odor and taste, a little sweet. Non-flammable, colorless at room temperature. The Second World War gave birth to the use and aircraft used for their systems. It was the war in speed zones of enemy aircraft in an attempt to attack their opportunities. The aircraft also kept running longer. This applied in the low oxygen atmosphere, especially in high altitudes.Nitrous Oxide Systems (NOS) are widely used because of its accessibility, ease of installation and simple design. Stimulate a vehicle with a CV that makes direct and popular. It is currently used in automotive racing car as a power engine performance must improve. They act as an oxidant, when exposed to high temperatures. They make the great performances by adding energy to the engine. The first racing cars using the technology of nitrous oxide systems, the cars of NASCAR in 1970. The underground use later spread to the cars which later banned.These systems in vehicles to improve performance by supporting the combustion process. This increases engine power. For combustion is produced, the oxygen present. Fuel in the same way oxygen to burn and the burning heat of the energy they produce in turn the engine. Pure oxygen is too strong to be introduced into the engine itself as the risk of explosion. This is because the compressor and this can cause the engine to explode. Therefore, it is mixed with fuel and introduced into the engine as a cocktail and this is a car with normal speed. To achieve high speeds, nitrogen added to the cocktail and the result is the formation of two gases, oxygen and nitrogen. This oxygen is in its pure state and the power of motor racing at the dispatch of a high speeds.Nitrogen is the residue after the formation of pure oxygen. It is an inert gas and is not possible for a reaction with an atom. The aim is to control the heat produced by the pure oxygen. Produces a cooling effect that reduces the heat. The NOS that are commonly used in wet and dry injections injections. The injection of dry N2O used alone. It is used to dry the fuel and the result is a less powerful engine. Right injection is a cocktail of N2O and fuel, resulting in a powerful motor. A limitation of nitrous oxide systems (NOS) is that the engine is notable for the cylinder pressure is now greater. This in turn destroys the crankshaft and pistons.
