近六、七年来,提高汽车性能的重点已由提高运行速度和功率转到节约燃料方面。汽车节油有很多方法。 (1)采用无内胎径向线轮胎。这是运材汽车节油较好的方法。这种轮胎能减小滚动阻力,节省燃料。采用这种轮胎可以提高运材车的载重量,也可以提高牵引性能。径向线轮胎有一层强度高的钢带圈,这种钢带圈抗弯曲,滚动好。据加拿大一家厂 In the last six or seven years, the focus on improving vehicle performance has shifted from increasing operating speed and power to saving fuel. There are many ways to save fuel. (1) The use of tubeless radial tire. This is a better way to save fuel for transportation vehicles. This type of tire reduces rolling resistance and saves fuel. The use of such tires can increase the carrying capacity of Timberwagon, can also improve the traction performance. Radial line tires have a layer of high strength steel band, this steel band bending, rolling well. According to a factory in Canada
