Secrets of the system

When watching the classic racing movies, are you curious how the drivers only need to push a special button, the car suddenly comes off?

The system helps the car run as fast as a rocket

Movie movie fans or street racing games, it must be no stranger to the scene of riders speeding against each other.

In particular, the driver of the driver is often "level" one more button. When a racer wants to overtake his opponent, he only needs to press a special button on the steering wheel, the car immediately zooms in like a shot - like in the picture below:

Surely everyone is curious about this "car" technology right? That is the NOS (Nitrous Oxide System) system - the system that helps the engine increase its operating capacity , causing the vehicle speed to skyrocket.

Perhaps many of you have heard about this system but have you ever wondered how it works? The following article will help you answer this.

Nitrous oxide - N2O is a gas molecule consisting of two nitrogen atoms linked to an oxygen atom. This is an unburnt gas compressed under high pressure into a liquid form to store in a container. If released from the flask, the liquid N ₂ O will return to the gaseous state.

Liquid N2O when introduced into the engine will become gaseous.

When nitrous oxide is put into the engine, an additional amount of fuel will also be added as fuel. Be aware that the amount of oxygen contained in nitrous oxide is about 33% - a significant difference compared to the amount available in the air (20%).

Under high temperatures inside the engine, the link between nitrogen and oxygen atoms is broken, creating a sudden increase in oxygen in the combustion chamber.

The extra oxygen helps to burn the added fuel initially, making the combustion process more powerful, thereby pushing the piston to move faster and generating more power for the engine.

A nitrous oxide system (nitrous oxide system - NOS) is the most complete way to add nitrous oxide and fuel at the same time. There are two types of NOS designed to be dry (dry) and wet (wet).

The dry type keeps the suction tip dry, and allows the vehicle's built-in fuel injector to control the additional fuel as the system only adds nitrous oxide to the suction tip.

In contrast, the wet type wetted the tip of the suction nozzle, taking control of the additional fuel by the injection system into the fuel-aspirated nitrous oxide throat.

When comparing advantages and disadvantages, dry NOS is considered as a simple installation and is cheaper than a wet type but does not provide a high engine capacity.

And the result after the installation is completed will be a vehicle with the ability to accelerate extremely . "virtual", can help speed the car beyond the clock table in the cockpit.

However, it should be noted that this is the process of "accelerating coercion" - by providing more oxygen in the combustion chamber, causing the engine to operate beyond its inherent capacity.

Therefore, the abuse of NOS will cause the engine to be quickly eroded and damaged. In addition, the installation of the system also needs to be very careful, because only a small error makes the amount of N ₂ O pumped too much will cause damage to the engine or even explosion.

Funfact about N ₂ 0

Nitrous oxide is also called ' laughing gas', because when inhaled this gas makes people feel excited and laugh. Some cases even cause hallucinations.

However, according to doctors' recommendations worldwide, nitrous oxide directly affects the heart and nervous system, if abuse can cause negative consequences such as depression or even death.
