NOS enhances engine power by injecting nitrous oxide into the engine. Therefore, when modifying NOS, at least the following hardware components must be included: a gas cylinder, nozzle, solenoid valve, and activation switch. Below is a detailed introduction: 1. Working Principle: N2O is compressed into a high-pressure liquid state and stored in a steel cylinder. It is then mixed with air in the engine to act as a combustion aid and burn with the fuel (N2O releases oxygen and nitrogen, where oxygen is the key combustion-supporting gas, while nitrogen helps cool the system). At high temperatures, N2O decomposes into two nitrogen atoms and one oxygen atom. The oxygen atom supports combustion, while the nitrogen atoms help cool the cylinders. This improves fuel combustion efficiency and boosts power. 2. Main Components: The solenoid valve is a crucial component that controls the nozzle's operation. Since NOS injection relies on the pressure inside the cylinder to deliver gas into the engine, a controller must be installed between the cylinder and the nozzle to regulate gas injection. The activation switch is another vital part that sends commands to the solenoid valve. It is typically installed directly below the accelerator pedal or at the end of the throttle cable. Some systems also use throttle voltage to detect throttle opening, allowing the driver to activate NOS when the throttle is fully opened.
