Nitrous Oxide Injection

By: subd0main

Nitrous is a term commonly used instead of nitrous oxide.Nitrous Oxide is a gas composed of 2 nitrogen and 1 oxygen atoms( N20).This gas has no smell,is colorless and it doesn't burn.It isn't toxic and inhaled in small amounts can produce reactions like laughter or giggling.Nitrous Oxide is an oxidizer agent that can increase the engine's power with 45% or more (it depends on the configuration) by allowing it to burn more fuel that it usually can.This way a nitrous oxide system brings additional horsepower to the engine.At high temperatures,nitrous oxide splits up into oxygen and nitrogen gas.This leads to an increase of the oxygen pressure bigger than it's pressure in the atmospheric air,allowing the fuel to burn efficiently.

Nitrous Oxide is not a fuel.It only allows the fuel to burn faster enlarging the power of the engine.

"NOS" is a term incorrectly used because it represents the name of a company that used to produce nitrous systems.The correct version recommended is Nitrous Oxide.

The nitrous systems can be divided in 3 categories:

1)"Dry"-In this kind of nitrous system,the upper intake of the fuel injectors is kept dry of fuel.The fuel flow can be increased in 2 ways:by rising the pressure in the fuel injection

system or by programming the vehicles' computer to increase the period of time in which the fuel injectors stay open for the engine cycle.

2)"Wet Single-Point"-This system makes the upper intake wet with fuel by introducing the fuel and the nitrous together.The system is more expensive and hard to install,by comparison with the "Dry" system,but it has the advantage of producing more power.

3)"Wet Multi-Point"-introduces fuel and nitrous straight into the intakes of the engine.The system measure the amount of fuel and nitrous received by each cylinder adjusting this amount for each cylinder so the other cylinders couldn't be affected.

Due to the ability of using more and bigger capacity solenoid valves,the "Wet Multi-Point systems are the most efficient and powerful among the nitrous systems.This system are used especially at racing cars.
