What is the chemical composition of automobile nitrogen?

The full name of NOS is nitrous oxide system, that is, nitrogen acceleration system. It is a product developed and produced by American Huali Company. At present, in the world racing, in order to improve the high specific horsepower in an instant, the liquid nitrogen oxide system used is NOS. In fact, as early as World War II, the German Air Force began to use NOS, and it was gradually used for linear acceleration after the war.

The working principle of NOS is to turn nitrogen dioxide (N2O), commonly known as nitrous oxide, into a liquid state under high pressure, and then put it into a steel cylinder, and then mix it with the air in the engine and burn it with the fuel (oxygen and nitrogen can be released, in which oxygen is the key combustion-supporting gas and nitrogen can help cool down), thus increasing the integrity of fuel combustion and improving horsepower. Because NOS provides additional combustion-supporting capacity (a lot of oxygen), it is necessary to increase the fuel injection after installing NOS. "If a horse wants to run, it must eat more grass." Fuel is the grass of the engine and the power of the engine is further improved. NOS, like turbocharging and mechanical supercharging, aims to increase the oxygen content in the engine mixture, improve the combustion efficiency and increase the horsepower. The difference is that NOS directly uses oxides, and the latter two achieve their goals by increasing air density through external force. Maybe someone will ask why nitrous oxide is directly used instead of oxygen. That's because it is difficult to control the stability of the engine (high temperature and explosive force) with oxygen, so oxygen is rarely used directly.

The refit shop suggests that NOS system should not be used for more than 1 minute each time, but in fact, according to the situation that the system switch needs to fully open the throttle, it usually takes only a few seconds to make the speed exceed 6000, and the computer automatically cuts off the oil.
