如果开着轮胎没气或气压不足的汽车外出上路,不仅会多耗燃油,而且可能会因爆胎而发生车祸。因此,不少车主会定期检测汽车轮胎的胎压。然而,汽车气压不足可能会因为各种偶然因素而随时出现。为了防止出现意外的胎压不足,美国研究人员开发出一种可以自动充气的轮胎。
If you drive a car with no air or under-pressure on the road, it will not only consume more fuel but may also cause a car accident due to a flat tire. Therefore, many owners will regularly test the tire pressure of car tires. However, the shortage of car pressure may occur due to various contingencies at any time. In order to prevent accidental under-pressure, U.S. researchers have developed a self-inflating tire.
