同诸多产业一样,作为人类的重要交通工具——汽车,在迈向21世纪的最后几年,它也加快了改进的步伐,变化得让人眼花缭乱。 车身轻型化 自1994年巴黎世界汽车展览会上展示出第一辆铝制轿车“奥迪A_8”以来.世界汽车铸造业已发生了翻天覆地变化,各大汽车公司,竞相在轻型化方面大做文章。因为,在巴黎汽车展览会上,汽车设计师们已清楚地看到:汽车越轻,耗用的燃料和排放的污染物就越少。这在高度重视环保的今天是相当重要的。 不过,纯粹使用金属铝取代钢制造汽车以减轻重量的做法也有其
Like many industries, as a vital transport for mankind, cars have accelerated the pace of improvement in the last years of the 21st century, with dazzling changes. Lightweight Body Since the first aluminum sedan, Audi A_8, was unveiled at the Paris World Motor Show in 1994, the world’s automotive foundry industry has undergone tremendous changes, with major auto companies vying to make a fuss about light-weighting. Because, at the Paris Motor Show, car designers have clearly seen that: the lighter the car, the less fuel consumed and the less pollutants emitted. This is very important today in a highly valued environment. However, there is also a practice of using metal aluminum instead of steel to make cars to reduce weight
