自从发生“石油危机”以来,许多国家十分重视内燃机代用燃料的研究。由于氢与醇是无污染或低污染的,贮存和运输又很方便,因此,许多科学家认为它们是大有前途的未来燃料。理想的清洁能源现在的内燃机,主要是采用汽油或柴油为燃料。内燃机运转时,排出的废气严重地污染环境。自七十年代以来,消除内燃机排气污染已成为世界所关心的一个重要问题。如果内燃机采用氢为燃料,只要设计正确,那么其燃烧产物为水蒸汽,对大气无污染。因此,氢是理想的清洁能源。卓有成效的节能措施 Since the “oil crisis”, many countries attach great importance to the study of alternative fuels for internal combustion engines. Because hydrogen and alcohol are pollution-free or low-polluting, easy to store and transport, many scientists consider them promising fuels of the future. Ideal clean energy The current internal combustion engine, mainly gasoline or diesel fuel. When the internal combustion engine is in operation, the exhaust gas discharged seriously pollutes the environment. Since the 1970s, eliminating the exhaust pollution of internal combustion engines has become an important issue of concern to the world. If the internal combustion engine uses hydrogen as the fuel, as long as the design is correct, the combustion products are water vapor, which is non-polluting to the atmosphere. Therefore, hydrogen is the ideal clean energy. Effective energy saving measures
