在中国柴油机已成为国民经济发展的主导动力,除了重型汽车以外,工程机械、农业机械、船舶、大型发电机组、内燃机车等,无一不见其身影。需求量大,造成柴油时常供应紧张,遍及全国的“柴油荒”屡屡出现。如何缓解柴油供应紧张的问题,一直是困扰国家燃料能源的难题。近10年来,国家围绕替代燃料做了大量工作,从乙醇到生物柴油,再到天然气,然而这些替代燃料不是限于资源就是限于使用条件,一时难以在全国范围内大规 Diesel engines in China have become the main driving force for the development of the national economy.
