Nitrous Oxide Tuning

Before I start talking about “NOS” I must say few things: first of all, azoth oxide is not a fuel (you will see later); secondly- NOS. is not used correctly, because NOS is a name of a company. The correct term is “Nitrous Oxide”.

Nitrous Oxide Tuning

We all know that the combustion take place because of the mix-up between the air and the gas (fuel) in the burning room. An engine works using the gas (fuel) and the pistons are pushing down in to the cylinder. If you want more power burn more gasoline for the pistons to be push with more force. That is what makes the car more powerful but this is impossible without a bigger quantity of oxygen. Nitrous Oxide Systems makes the engine to burn more gas than it usually and so the power raise.

Normally, the air that we breathe contains: 20.947 % oxygen; 78.08 % azoth and less than 1 % other gases. Azoth oxide is the same, but with a bigger proportion of oxygen: 36.35 %. Azoth oxide is colourless, odourless and non-inflammable and has 2 azoth atoms and 1 oxygen atom. So, there is the N2O name. The taste is a little sweet, but non-toxic and not irritant, but in small quantities can produce “laughing”.

How it works? Well, at the same time with the burning process, at almost 3000 Celsius degrees, azoth oxide decomposes in azoth and oxygen. The oxygen makes that a bigger quantity of fuel is burned. The power surplus is from the fuel. If you put only azoth oxide, without fuel it will not be obtained higher power, only a destructive power raise that will make the engine to burn the fuel.

Azoth oxide is a gas and used for cars is compressed in a tube, in liquid form. From the tube (that usually stays in the trunk), a high pressure hose makes the connection with the engine. Here, an electric valve named solenoid it’s used to get out the azoth oxide from the engine, when this wants that. In “wet” systems, a hose for the gas is controlled by another solenoid to set free the fuel into the engine at the same time with the azoth oxide.

Dry system. At a dry system the azoth oxide is pulverized in the air pipe without any supplementary fuel. At this kind of system, necessary gas surplus is obtained with the changes of engine parameters. The computer is “fooled” to give more fuel. Dry systems are very easy to install and are indicated to people who use azoth oxide for the first time.

Wet system. At this system, both azoth oxide and the supplementary fuel are pulverized at the same time. Wet systems put in the air pipe azoth oxide wet with fuel. This system works the best for turbo engines.

Another good thing about the nitrous oxide systems is the “cold effect”. The cold cold effect is more dens and has more oxygen atoms, so that makes more fuel to be burn and so more power. Against our atmosphere, azoth is pulverized from a tube in which the pressure is very high. So, when the azoth leaves the cold tube, from its liquid form it transforms in a gas form so it gets into the engine. Azoth oxide boil at -88.50 Celsius degrees, and once pulverized will start to boil from that moment, because the temperature in that zone is much higher. In this process, the heat can cause a dropdown for the temperature. Taking a 400 hp engine, this will take instantly to a higher power with 30 hp only because of this cold effect and that will be good for the engine, too.

Azoth oxide must be kept at a pressure between 900 and 1000 to obtain the best power. This will be great for the summer, but will be a big problem in the winter, especially at winter nights.

Here you can see the pressure variation because of the temperature:
At -34 Celsius degrees – tube pressure is 167; at -23 Celsius degrees- tube pressure is 240; at -6 Celsius degrees- tube pressure is 387; at 0 Celsius degrees- tube pressure is 460; at 10 Celsius degrees- tube pressure is 590; at 15 Celsius degrees- tube pressure is 675; at 27 Celsius degrees- tube pressure is 865; at 36 Celsius degrees- tube pressure is 1069.

You can see that at 100 Celsius degrees, the pressure is 590. Too little. This problem can be resolved putting a heater tube. This has a thermostat, it is easy to install and controlled automatic. All car producers think that a good heater is very important to a nitrous oxide system.

    im a mechanical engg student…….im very interested in automobile field..recently only i came to know about NOS….
    i have an idea of fixing NOS in ENFIELD BULLET(motor bike) will it be possible.?
