Long-time driving will increase the temperature of the tires, which also increases the possibility of a flat tire. The harm that flat tires bring to high-speed cars is often fatal.
A few days ago, the reporter learned from the dealers that charging the tires with nitrogen gradually became popular among car owners. However, what is the advantage of using 10 yuan to fill one tire of nitrogen and 10 yuan to fill the air of four tires? Recently, the reporter consulted with experts in the automotive industry on this issue.
Nitrogen tires make driving more stable and comfortable. "Now the owners of cars are adding more nitrogen. Old customers do not need to recommend them at all. They are all active in requesting nitrogen filling. There are also often car owners consulting about the benefits of nitrogen filling tires." "The garage owner, Mr. Dong, told reporters that filling at least 10 yuan per tire is sufficient for filling with nitrogen, while filling the traditional air, 10 tires can be sufficient for 5 tires.
It is understood that nitrogen is an inert diatomic gas, very inert chemical properties, gas molecules than oxygen molecules, compared with the air is not prone to thermal expansion and contraction phenomenon, it can reduce the tire deformation. Moreover, its penetration into the tire's sidewall is about 30% to 40% slower than air, which can better maintain a stable tire pressure, improve the tire's running stability and driving comfort.
Since the audio conductivity of nitrogen is only 1/5 of that of air, the use of nitrogen can effectively reduce tire noise and increase the quietness of driving.
Decreasing puncture rate to make driving safe According to the statistics of the traffic control department, 46% of accidents occurring on the expressway are caused by tire failure, and only punctures account for 70% of total tire accidents. It can be seen how important the safety of the tyre is to the car.
According to Mr. Jiang, a senior automotive engineer, the temperature of tires will increase due to constant friction between the car and the ground. Especially at high speeds and during emergency braking, the temperature of tires and their filling gas will rise rapidly due to thermal expansion and contraction. The principle of contraction caused a sudden increase in tire pressure. As a result, the possibility of a puncture accident has increased.
At the same time, because the tire itself will also accelerate aging due to the increase of temperature, it will reduce the fatigue strength, resulting in more severe wear tread rubber. Compared with general high-pressure air, nitrogen has a low coefficient of thermal expansion, low thermal conductivity, and a slow temperature rise. This, combined with its non-flammable characteristics, also greatly reduces the chance of a puncture.
Nitrogen-filled tires save the cost of car conservation in disguised form. “With nitrogen, tire pressure is relatively stable, and it can reduce the possibility of irregular friction of the tire, so as to improve the service life of the tire. To a certain extent, this is to save the cost of vehicle maintenance. Mr. Dong said that because nitrogen does not contain oxygen, sulfur, oil, water, and other impurities in the air, it can effectively reduce the degree of oxidation of the inner lining of tires and the phenomenon of rubber corrosion, and it will not corrode metal rims. Minimizes rust on the rim. According to comparative experiments conducted by relevant agencies abroad on tire filling with nitrogen and air filling, the nitrogen-filled tires run 26% more mileage than air-filled tires. And nitrogen-filled tires can make vehicles use closer to the car's design fuel consumption index. At the same time, nitrogen-filled tires save 2% to 10% more than air-filled tires. Effectively reduced air pollution, and even ran over 50,000 kilometers still does not require air supplement.
