Why is nitrogen acceleration called NOS

is an abbreviation for English.

Nitrous Oxide System (NOS) Nitrogen Acceleration System.

Nitrogen pressurization is commonly known as NOS, and NOS is made of"nitrousoxide system", abbreviated, but what exactly is NOS? Simply put, it is a system in which nitrous oxide (N20) is forcibly poured into the engine. In order to make the engine produce more power, it is necessary to let the engine inhale more air, and with the appropriate proportion of fuel, so as to produce a higher oil and gas burst efficiency, turbo or super charger system, that is, the supercharger is used to compress the air into the engine, so that the engine can produce more power under the same displacement volume.

The same is true for the basic principle of the NOS modification, except that the structure of the NOS is much simpler, and the NOS is not just a simple compressed air, but uses the aforementioned nitrous oxide to make the engine more efficient.

NOS stands for Nitrous Oxide System, that is, Nitrogen Acceleration System.

Please see for details.

NOS Nitrogen Acceleration System, the accurate translation of this system should be: Nitrogen Oxide Acceleration System. It is a product developed and produced by Holley Company in the United States.

In the current World Drag Racing, the liquid NOx system used is NOx in order to increase the horsepower in an instant. In fact, as early as World War II, the Luftwaffe began to use NOS, and after the end of the war, it was gradually used for straight tail pipes, also known as car tail pipes, which are parts installed at the tail end of the original exhaust. Depending on the type of tailpipe, there are several actual functions.

1. There is a special tail pipe for fire safety, such as those used in tank trucks and some special vehicles.

2. Pure aesthetic effect. There are a lot of chrome tailpipes that are attached to the original iron exhaust ports. Increase aesthetics.

3. Sports modification, which is mainly to increase the exhaust sound The exhaust will produce a roar like a sports car through this tailpipe. But there is no actual improvement in motivation.

These middle tailpipes, if properly installed, do not affect the exhaust.

4. The tail throat is divided into with and without silencing net, of course, the main function of the silencing mesh is to have a certain silencing! Line Acceleration Race.

It's a kind of acceleration setting in the game that is faster than normal acceleration.

NOS is to increase the explosive power after nitrous oxide is injected into the engine, so at least the following hardware must be included when modifying NOS, which are gas cylinders, nozzles, solenoid valves and start switches.

A gas cylinder is a steel container filled with nitrous oxide, which not only has a difference in appearance and size, but also has specifications such as empty weight, gross weight and pressure in the cylinder. The nozzle is like the fuel injector in the engine fuel supply system, the larger the nozzle diameter, the more gas is sprayed, and the greater the benefit to horsepower; The solenoid valve is an important element to control the nozzle operation, because the injection principle of NOS is to use the pressure in the bottle to pour gas into the engine, so a controller must be installed between the gas cylinder and the nozzle to control the gas injection speed; The start switch is an important part that provides instructions for the solenoid valve to actuate, which is generally installed directly below the accelerator pedal or at the end of the throttle cable, but there are also throttle voltages used to sense the throttle opening, allowing the driver to activate the NOS at the same time when the throttle is fully open.

However, in addition to the above four main structures, in fact, in the NOS system, in addition to the switch of the gas cylinder itself, one or two safety switches must also be installed, otherwise the long-term use of NOS will lead to excessive pressure in the combustion chamber, and the temperature will rise sharply.

NOS is to increase the explosive power after nitrous oxide is injected into the engine, so when modifying NOS, it must contain at least the following hardware, namely gas cylinders, nozzles, solenoid valves, and start switches.

Gas cylinders are steel containers filled with nitrous oxide and blind halls, in addition to the difference in appearance and size, there are also specifications such as empty weight, total weight and pressure in the cylinder; The nozzle is like the fuel injector in the engine fuel supply system, the larger the nozzle diameter, the more gas is sprayed, and the greater the benefit to horsepower; The solenoid valve is an important component to control the nozzle actuation, because the injection principle of NOS is to use the pressure in the bottle to fill the gas into the engine, so a controller must be installed between the gas cylinder and the nozzle to control the injection of gas; The start switch is an important part that provides instructions for the solenoid valve to actuate, which is generally installed directly below the accelerator pedal or at the end of the throttle cable, but there are also throttle voltages used to sense the throttle opening, allowing the driver to activate the NOS at the same time when the throttle is fully open.

However, in addition to the above four main structures, in fact, in the NOS system, in addition to the switch of the cylinder itself, one or two safety switches must be installed, otherwise the long-term use of NOS will cause the pressure of the combustion chamber to be too large, and the temperature will also rise sharply.

For safety reasons, it is generally recommended not to use it continuously for more than 1 minute, otherwise the engine will be damaged due to excessive load. In addition, the installation position of the nozzle and the control accuracy of the solenoid valve should not be overlooked. The position of the nozzle will affect the gas flow rate and atomization effect, so it is generally installed at a distance of 15-3ocm from the throttle; The accuracy of the solenoid valve is very important, because the N0S must be injected with the throttle fully open, if the throttle opening angle is insufficient or it has been closed, it will cause nitrous oxide backflow, and even backfire in severe cases, at this time, the flow meter or air core can be easily damaged.
