Nitrous Oxide

What is Nitrous Oxide?

Nitrous Oxide is a colorless, non-flamable gas (at room tempurature) that is used in automotive racing to dramatically increase horsepower. Nitrous Oxide does not increase horsepower by buring, it is an Oxider that allow an engine to burn more air and gas by significantly reducing the tempurature in the intake system.

How it works

Nitrous Oxide components usally come in kits that have most of the parts you need to install the kits on you vehicle. They consist of a bottle that holds the Nitrous Oxide (usaully installed in the trunk or rear of the vehicle), tubing to run the gas from the rear of the vehicle to the engine, a controller that is located within the reach of the driver, and nozels or adapter plates to inject the Nitrous Oxide into the engine.

Types of Vehicles

You can get Nitrous Oxide kits for just about any type of vehicle. The majority of Nitrous systems are installed on cars or trucks. But some companies also make systems for Motorcycles, ATV's and even Snowmobiles.

Types of Systems

There are 2 main types of Nitrous systems, Wet and Dry systems. The designation refers to the intake manifold. If the fuel system goes through the intake manifold, the mainfold gets wet and therefore it is considered a wet system. If the fuel injectors inject the extra fuel required then the intake manifold stays dry and therefore it is considered a dry system.

Wet Systems

There are 2 types of wet systems, Single Point and Direct Port. Wet systems typically allow greater horse power increases over Dry Systems.

Wet Single Point Systems

Wet single point systems inject Nitrous Oxide into the manifold at a single point so it mixes with the fuel and air mixture.

Wet Direct Port Systems

Direct Port systems have individual Nitrous Oxide injectors for each port. These systems are more complex and therefore more extpensive than Single Point systems.



Dry Systems

Dry Systems are similar to Wet systems in the way they deliver Nitrous. The difference is in the way the fuel is delivered to the engine. The fuel does not travel through the manifold to the cylinder head. The fuel is delivered after the manifold and therefore the manifold is kept dry of fuel.

Programs the take Nitous Oxide into account

We have 3 programs that work with Nitrous Oxide when conducting Engine Simulation. Engine Analyzer v3.2, Engine Analyzer Plus v3.2 and Engine Analyzer Pro v3.9.
