Nitrous Oxide Systems (NOS) represent a sophisticated power enhancement technology that transforms engine performance by introducing additional oxygen into combustion chambers. By decomposing nitrous oxide into oxygen and nitrogen, these systems enable dramatically increased fuel burning efficiency, generating substantial horsepower gains through precise chemical and mechanical interactions within automotive engines.
What Happens During Nitrous Oxide Decomposition?
Chemical Transformation Process
Nitrous oxide (N₂O) undergoes a remarkable chemical decomposition when injected into an engine’s combustion chamber. The key transformation involves:
- Oxygen Release: N₂O breaks down into oxygen (O₂) and nitrogen (N₂)
- Oxygen Concentration: Increases from standard 21% to 36.36%
- Temperature Range: Decomposition occurs at 570-580°F
Pressure and Temperature Dynamics
| Parameter | Specification |
|---|---|
| Liquid Pressure | 11 lbs per degree Fahrenheit |
| Temperature Drop | 60-80 degrees during vaporization |
| Volumetric Efficiency | Increased due to charge cooling |
