未来的汽车燃料应该是对环境友好,其排放的废气不污染大气,不产生温室效应、光化学污染和酸雨等。下面简介两种未来可能采用的汽车燃料: 1 氢气 汽车采用氢气作燃料代替传统的汽油或柴油,则排放物不是二氧化碳和氮氧化物等而是水。这样的“绿色”交通模式带来了一个新概念“氢经济”。 The future of automotive fuel should be environmentally friendly, the exhaust emissions do not pollute the atmosphere, does not produce greenhouse effects, photochemical pollution and acid rain and so on. Here are two possible types of automotive fuels that may be used in the future: 1 Hydrogen uses hydrogen as a fuel instead of conventional gasoline or diesel, and emissions are not carbon dioxide and nitrogen oxides but water. This “green” mode of transportation has brought a new concept of “hydrogen economy.”
