Car tire inflation: what's the difference between regular air and nitrogen filling? What are the advantages and disadvantages?
3. the use of nitrogen to prolong the service life of tires, tire pressure stable volume change is small, greatly reducing the possibility of irregular tire friction, such as crown grinding, shoulder grinding, eccentric wear, improve the service life of the tire; rubber aging is due to the oxidation of oxygen molecules in the air, its strength and elasticity decreased after aging and, there will be one of the causes of cracking phenomenon, then shorten the life of tire. Nitrogen separation device can greatly eliminate the oxygen in the air, sulfur, oil, water and other impurities, effectively reducing the tyre liner oxidation degree and rubber corrosion phenomenon, no corrosion of the metal rim, prolong the service life of the tire, but also greatly reduce rim rust situation.
4. to reduce fuel consumption, protect the environment increased less than the tire pressure and heated rolling resistance, will cause the car at the time of increased fuel consumption; and nitrogen addition can maintain the stability of the tire pressure, tire pressure to reduce the delay, the dry and oily water, low thermal conductivity, temperature rise of slow, elevated temperature reduce the tire when walking, and tire deformation small grip raise, lower rolling resistance, so as to achieve the purpose of reducing fuel consumption.
2., to prevent flat tire and gas shortage, tire blowout is the number one killer in road traffic accidents. According to statistics, in the highway, 46% of the traffic accidents are caused by tire failure, of which, a flat tire accounted for 70% of the total number of accidents. When the car is running, the tire temperature will rise due to friction with the ground, especially in high speed and emergency braking, the gas temperature will rise rapidly, tire pressure surge, so there will be a possibility of a flat tire. But the high temperature causes the tire rubber aging, the fatigue strength drops, the tread wear is fierce, is also the important factor which possibly the tire burst. Compared with the general high pressure air, high purity nitrogen for anaerobic and almost free of moisture without oil, its low thermal expansion coefficient, low thermal conductivity, slow heating, reducing the tire heat accumulation rate, but also can not help but not other characteristics, so it can greatly reduce the chance of puncture.
1. to improve the stability of the tyre and comfort is almost double of inert gas nitrogen atoms, chemical nature of inert gas molecules than oxygen molecules, not easy to deformation of thermal expansion and contraction, small amplitude, the penetration of tire wall speed more slowly than air about 30 ~ 40%, to maintain the stable tire pressure, improve stability the tyre, ensure driving comfort; nitrogen low conductivity is equivalent to ordinary audio, air 1/5, the use of nitrogen can effectively reduce tire noise, improve the degree of quiet running.
Nitrogen is an inert gas, the coefficient of expansion is low, it does not easily rise with the increase of ambient temperature. It can maintain normal tire pressure for a long time, and greatly reduce the rate of tire blowout. When nitrogen is filled for 50 thousand kilometers, it still does not need air supply, and dry nitrogen does not contain moisture, and will not cause oxidation of the rubber lining of the tire.
