What Does Nitrogen in Cars Mean?
1 Answers
Automotive nitrogen refers to the nitrogen gas used in vehicles, which plays a crucial role in car performance. Below is a detailed introduction to the functions of nitrogen in cars: 1. Enhances tire stability and driving comfort: Nitrogen is an almost inert diatomic gas with extremely low chemical reactivity. Its molecules are larger than oxygen molecules, making it less prone to thermal expansion and contraction, with minimal deformation. Nitrogen permeates through tire walls about 30-40% slower than air, helping maintain stable tire pressure, improving driving stability, and ensuring a comfortable ride. Additionally, nitrogen's low audio conductivity effectively reduces tire noise, enhancing driving quietness. 2. Prevents tire blowouts and underinflation: Compared to regular high-pressure air, high-purity nitrogen is oxygen-free and nearly devoid of water and oil. Its low thermal expansion and conductivity result in slower temperature increases, reducing the rate of heat buildup in tires and significantly lowering the risk of blowouts. 3. Extends tire lifespan: Using nitrogen greatly reduces the likelihood of irregular tire wear, thereby increasing tire longevity. Nitrogen separation devices can effectively remove oxygen, sulfur, oil, water, and other impurities from the air, minimizing oxidation of the tire's inner liner and rubber corrosion, further prolonging tire life.
