The inflation of automobile tires is a common thing in our daily life. Many drivers' friends will entangle a problem when inflating the tires. Is it filling air or nitrogen? Will nitrogen filling bring benefits to the car? There are also some drivers who think that charging air is cheaper. If nitrogen is too expensive, it might be better to charge the air. So Xiao Bian today explained to the driver's friends what the benefits of nitrogen filling would bring to the car. The four advantages of nitrogen filling in automobile tires: 1. Tire filling nitrogen can reduce tire noise Nitrogen is normally a colorless, odorless, odorless gas and is generally non-toxic. Nitrogen accounts for 78.12% (volume fraction) of the total atmospheric volume. Under standard conditions, the gas density is 1.25g·dm-3. When nitrogen is cooled to -195.8°C under standard atmospheric pressure, it becomes a liquid with no color, and it is cooled to At -209.86°C, liquid nitrogen turns into a snow-like solid. The solubility of nitrogen in water is very small. At room temperature and pressure, only about 0.02 volume of nitrogen is dissolved in one volume of water. It is a gas that is difficult to liquefy. The solubility in water is very small. At 283K, a volume of water can dissolve about 0.02 volume of N2. Nitrogen will liquefy to a white liquid at a very low temperature. When the temperature is further lowered, a white crystalline solid will form. Therefore, the chemical properties of nitrogen are inactive, and the audio conductivity is very low. It is equivalent to only 1/5 of that of ordinary air. Nitrogen filling can effectively reduce the noise of the tire during running, and it is effective for improving the quietness of driving. 2. Saves fuel for cars In the process of driving a car, the lack of tire pressure and the increase in resistance after heating will result in increased fuel consumption of the vehicle. The nitrogen filling can maintain a very stable tire pressure. The low thermal conductivity of nitrogen and the slow temperature increase effectively reduce the increase in temperature of the tire during high-speed driving, thereby reducing the rolling resistance and achieving significant reduction in fuel consumption. 3. Nitrogen filling can extend tire life After the use of nitrogen, the volume change of the tire pressure stability is small, which greatly reduces the possibility of irregular friction of the tire, such as crown grinding, shoulder grinding and eccentric wear, which improves the service life of the tire. The aging of rubber is caused by the oxidation of oxygen molecules in the air. After aging, its strength and elasticity decrease, and cracking occurs. This is one of the reasons that shortens the service life of tires. The nitrogen separation device can largely exclude oxygen, sulfur, oil, water and other impurities in the air, effectively reducing the degree of oxidation of the inner liner layer of the tire and the phenomenon of corrosion of the rubber, and does not corrode the metal wheel rim, prolonging the tire's The service life also greatly reduces the rustiness of the rim. 4. Reduce the occurrence of puncture When the car is driving, the temperature of the tire will increase sharply due to friction with the ground. Especially during high-speed driving, the temperature of the tire rapidly rises and the tire pressure suddenly increases. Editor's Note: The Benefits of Nitrogen Filling in Vehicle Tires Have you got it? Xiao Bian suggested that owners of vehicles in daily use, if there is no special situation, it is best to charge nitrogen through the car tires. Although the price of nitrogen is expensive, repairs and tire replacement are more expensive.
