What is a Nitrous Oxide System (NOS) and How Does It Work?

A Nitrous Oxide System (NOS) is a performance-enhancing modification commonly used in vehicles to temporarily increase engine power. The system injects nitrous oxide (N2O) into the engine’s intake, which allows for more oxygen during combustion. This results in a significant boost in engine performance by enabling a higher amount of fuel to be burned, increasing the power output in short bursts.

Although nitrous oxide is typically used in racing or high-performance applications, it is also available for street cars. The system is controlled through various components such as the nitrous tank, solenoids, and the distribution system. These elements work together to ensure that the right amount of nitrous oxide is delivered to the engine in a precise and safe manner.

How It Works

The basic operation of a nitrous oxide system can be broken down into the following steps:

  1. Storage: Nitrous oxide is stored in a pressurized tank, usually located in the trunk or rear compartment of the vehicle.
  2. Activation: The system is activated either by a button or a throttle position sensor, which triggers the release of nitrous oxide.
  3. Injection: Once activated, nitrous oxide is injected into the intake manifold, mixing with air and fuel before entering the combustion chamber.
  4. Enhanced Combustion: The added oxygen from the nitrous oxide allows for more fuel to burn, resulting in an increase in engine power.

Key Components
