Nitrous oxide is a heavily reinforced three-atom molecule comprised of two parts nitrogen and one part oxygen. The nitrogen molecules lessen explosion and control the blaze of the ignition blend inside the chamber. The oxygen is the genuine power added substance here, however, because of its weight rate in the blend compared to the typical atmospheric air your engine generally breathes 36 percent versus 23.6 percent oxygen, which implies that you wind up with considerably more air in the burning chamber to fuel the fire.
Put away in a fluid state somewhere around 900psi and 950psi, it changes from a fluid to a gas when discharged into the intake manifold. During this procedure, its temperature drops to 88°C, retaining large amounts of heat from the intake charge and accordingly allowing expanded oxygen content. As a bonded particle, nitrous oxide won't burn; the molecules should separate first. This happens inside the ignition chamber at a little more than 300°C. Once separated, the two gasses approach their work. But, both nitrogen and oxygen are inactive gasses, so including all that additional oxygen is pointless unless you add more ignitable fuel to encourage off it. Thus, while numerous individuals mistakenly believe that the additional power originates from the gas detonating, this is not the situation. It basically infuses a ton more air into the chamber, similarly as a turbo or supercharger would.

Nitro boost is a concept that has been around for a while as early as during World War II. Some aircrafts had nitrous oxide injection systems in their engines. Today, some classes of car racing usually allow nitrous oxide applications. 

Before using nitrous oxide in cars, automakers studied many factors and did precise calculations to insure safety. They make sure there are no backfires as a result of fuel pooling in the manifold or uneven distribution of the mixture. They take necessary precautions as the injection system can cause explosions under the hood. 

The two types of nitrous systems that deliver nitrous oxide into the intake manifold are dry and wet, with four conventional delivery methods: 

  1. Single nozzle
  2. Direct port
  3. Plate
  4. Bar

The majority of nitrous systems make use of particular jets and pressure calculations to deliver the desired amount of the gas and create an efficient air-fuel-ratio for the boost required.

The two types of nitrous systems are:

1. Dry Nitrous System

Only nitrous oxide is delivered by a single nozzle delivery method, which injects fuel through a separate channel, the fuel injector. There are two ways to increase the amount of fuel flow - by increasing the pressure and by increasing the time that the fuel injector is open. 

2. Wet Nitrous System

In wet nitrous systems, nitrous oxide is combined with fuel and then delivered to the intake manifold. A special nozzle is used to measure the fuel and nitrous required. This system has an advantage over the dry system because it is more efficient.

This system supports all the methods of delivery and can be redesigned to distribute the mixture to the combustion chambers evenly, making it viable for carbureted and throttle body injected systems.
