Tire why nitrogen filling

Nitrogen is an inert gas, in the case of very high temperatures, its temperature changes, which can effectively prevent the benefits of another point of puncture nitrogen can reduce tire impatient voice for our quality of life and create more beautiful conditions. Nitrogen is already widely used in the southern region, the effect has been the recognition of the faithful car.

1. Improve the tire driving stability and comfort

Nitrogen is almost inert to the diatomic gases, the chemical nature of inactive gas molecules are larger than oxygen molecules, and difficult to heat and cold, the small magnitude of deformation, its permeation speed of the tire wall is slower than that of air, about 30 to 40 percent can be maintained stabilize the tire pressure, tire driving stability, ensure driving comfort; nitrogen audio conductivity is low, is equivalent to 1/5 of the ordinary air, using nitrogen can effectively reduce the tire noise and improve quietness traveling.

Prevent puncture and lack of air grind line

Puncture is the number one killer in road traffic accidents, according to statistics, 46% of accidents are caused by tire failure on the highway, a flat tire one accounted for 70% of the total tire accident. Driving the car, the tire temperature rise due to friction with the ground, especially at high speeds and the emergency brake, the gas temperature in the tire will increase rapidly, tire pressure surge, so there will be the possibility of puncture. The high temperatures cause tire rubber aging, fatigue strength decreased, severe tread wear, and may puncture the important factors. Compared with general high pressure air, high purity nitrogen as anaerobic and almost free of water does not contain oil, and its low coefficient of thermal expansion, low thermal conductivity, the temperature was raised slowly, and reduces tire heat accumulating speed, non-contingent nor Assistant contingent characteristics, it is possible to greatly reduce the chance of puncture.

3. Extend tire life

Using nitrogen gas, the the tire pressure stable volume change is small, and greatly reduces the possibility of irregular tire friction, such as crown grinding tread shoulder wear, partial wear, and to improve the life of the tire; aging of rubber is subject to the oxygen molecules in the air oxidation due to the decline in its strength and elasticity, aging and there will be cracking phenomenon, this time caused by one of the reasons for the shortened life of the tire. Nitrogen separation device can greatly limit to exclude the air of oxygen, sulfur, oil, water and other impurities, effectively reducing the degree of oxidation of the inner liner layer of the tire and rubber corrosion phenomenon, does not corrode metal rim, extending tire life, but also greatly reduces the status of the rim rust.

4. Reduce fuel consumption and protect environmental

Lack of tire pressure and heated scroll the yin force the increase will be caused by the increase in fuel consumption when the car is traveling; nitrogen can maintain stable tire pressure, delaying the tire pressure to reduce outside, its dry and not oil-free water, thermal conductivity low, heating up the slow characteristics, to reduce the increase in temperature in the tire when walking, as well as small deformation grip improve and reduce the rolling resistance, so as to achieve the purpose of reducing fuel consumption. You know aircraft tires inflated what gas it? Is nitrogen!

Because the nitrogen gas is an inert gas, in the low penetration within the tire can be maintained tire pressure stable, reduce puncture probability, so that the tire life extension, and to reduce the vibration of the tire in an irregular road surface, so that the vehicle is traveling smoothly, it has a volume conductivity low function, thus greatly reducing the tire and the ground friction generated when the noise, and so on. Especially febrile climate period, on the freeway, nitrogen tire can do now its strengths.

The relevant U.S. authorities tires with sufficient nitrogen and charge air contrast experiments, the statistical results show that in the experiment than air-filled tire filled with nitrogen gas to run more than 26% of the mileage.

Nitrogen tire inflation, tire pressure design can achieve fuel consumption indicators in automotive design. Experimental results show that nitrogen tire 2-10% more fuel efficient than the air-filled tires. Effective in reducing air pollution.

The American tire filled with nitrogen experiments relevant authorities. After the test, the statistical results showed that the tires filled with nitrogen tire and charge air traveling at the same speed, the former than the latter will run more than 1/5 of the journey;

The Brazilians practice, nitrogen gas tire traveling fifty thousand kilometers still do not need qi.

Nitrogen tire more resistant to wear, than the pneumatic tire is not reached on the damaged tire tread loss index, nitrogen filling the tire to run an average mileage, 48% more than the air-filled tires.
