燃料燃烧对空气的污染程度与燃料的种类关系极大。用氢作燃料似乎是理想的,因为可获得完全不含杂质(如硫)的纯氢,所以能完全燃烧,最后只产生水。但是,在燃烧温度下会产生一些氧化氮。燃烧天然气则可能产生一些一氧化碳和一些未完全燃烧的燃料。石油和
The extent of fuel pollution on air is very much related to the type of fuel. It seems ideal to use hydrogen for fuel, since pure hydrogen is completely free of impurities (such as sulfur) so that it can be completely combusted and finally only water is produced. However, some nitric oxide is produced at the combustion temperature. Burning natural gas may produce some carbon monoxide and some incomplete combustion of fuel. Oil and
