Nitrous Oxide Systems, commonly known as NOS, are a popular way to boost engine power in cars. But how exactly does NOS work? This system isn’t magic; it’s a carefully engineered setup that introduces nitrous oxide into your engine to enhance combustion. Understanding the components of a NOS system is key to appreciating how it delivers that exhilarating burst of speed. Let’s break down the essential parts that make it all happen.
Key Components of a NOS System
A typical nitrous oxide system is composed of several crucial parts, each playing a vital role in the process of delivering that extra horsepower.
Nitrous Oxide Tank

The heart of the NOS system is the nitrous oxide tank. These tanks are built to safely store liquid nitrous oxide (N2O) under high pressure. Constructed from robust materials, they are designed to withstand significant internal pressure. Safety is paramount, so each tank includes a pressure release valve as a critical safety feature. The size of these tanks can be customized based on the user’s needs and how much nitrous oxide they want to store for their performance enhancements.
Solenoids and Delivery Lines

To precisely manage the introduction of nitrous oxide and fuel into the engine, solenoids are used. These are essentially electronically controlled valves that act as gatekeepers, regulating the flow of both nitrous oxide and, in wet systems, additional fuel. Maintaining the correct ratio of nitrous and fuel is critical for both optimal performance gains and engine safety. Delivery lines are equally important; these high-quality hoses are responsible for safely transporting the nitrous oxide and fuel from their respective tanks to the engine’s intake system.
Nozzle or Plate

The point where nitrous oxide enters the engine’s air intake system is through either a nozzle or a plate. These two methods differ slightly in their approach. A nozzle system works by directly injecting nitrous oxide into the intake airstream, concentrating the delivery at a specific point. Conversely, a plate system is designed to be mounted between the intake manifold and the throttle body. This placement allows for a more even distribution of nitrous oxide across all cylinders, which can be beneficial for balanced performance enhancement.
Activation Switches

Control is key, and activation switches give the driver the ability to decide precisely when the nitrous oxide system engages. These switches can be as simple as a push-button, giving manual, on-demand control. More sophisticated systems offer integrated activation based on specific parameters like reaching a target RPM or achieving a certain throttle position. This automation provides a more seamless and potentially safer integration of the nitrous boost during driving.
Pressure Gauge and Bottle Heater

To ensure the nitrous oxide system operates safely and effectively, a pressure gauge is essential. It continuously monitors the pressure within the nitrous oxide tank, ensuring it remains within a safe and effective operating range. Some systems also incorporate a bottle heater. This is particularly useful in colder climates as it helps maintain the temperature of the nitrous oxide. Consistent temperature is crucial because it affects the pressure and vaporization of the nitrous oxide, directly influencing the system’s performance.
Purge Valve

An additional component that enhances the consistency and power of the NOS system is the purge valve. Its function is to release any nitrous oxide that might be in the delivery lines before it reaches the engine. This purging action is important because it removes any trapped air pockets in the lines. Air pockets can cause inconsistent nitrous flow, disrupting the intended boost. By ensuring a clear path of nitrous oxide, the purge valve contributes to a more reliable and powerful performance enhancement when the system is activated.
Conclusion
Each part of a nitrous oxide system works in concert to deliver a performance boost to your vehicle’s engine. From storage and controlled delivery to precise activation and safety measures, understanding these components is vital for anyone looking to utilize NOS. By carefully managing the introduction of extra oxygen through nitrous oxide, these systems offer a significant increase in power, transforming the driving experience when needed.
