目前,世界轿车工业正面临一场革命。面对消费者对高性能汽车的需求,同时面对环境保护、燃料限制和安全性等越发严格的标准,一些发达国家的汽车制造商,正着手研制21世纪初的汽车。据专家预测,节省能源、减少污染、安全舒适及智能化,将是21世纪汽车工业追求的目标。 竞争的目标:节能汽车 现今世界上的石油,很大一部分是被公路上的汽车吃掉的,目前正在研究的太阳能汽车、用氢气作动力的汽车,其设想固然很好,但不是短时间可以推广的。就目前条件说,省油还是最实际的办法。据一项调查显示,在西方市场上,仍然有62％的人希望买省油车。 汽车省油一靠内部发动机的改造,二靠外壳流线型的改造。利用气动技术设计出更合理的车体外形,是达到减少阻力、降低油耗、提高燃料经济性的主要途径。 另外,大量使用塑料、铝和其他轻质材料制造车
At present, the world car industry is facing a revolution. In the face of consumer demand for high-performance cars and the increasingly stringent standards of environmental protection, fuel restrictions, and safety, automakers in some developed countries are embarking on the development of cars in the early 21st century. According to experts’ predictions, energy conservation, pollution reduction, safety, comfort and intelligence will be the goals pursued by the automotive industry in the 21st century. The goal of competition: Energy-saving cars The oil in the world today is largely eaten by cars on the road. Solar cars and hydrogen-powered cars that are currently being researched are very good in their imagination, but not for a short period of time. Promotional. As far as the current conditions are concerned, fuel saving is still the most practical method. According to a survey, in the Western market, 62% still hope to buy fuel-efficient cars. The fuel-efficient car depends on the transformation of the internal engine, and on the other hand, the streamlined transformation of the shell. Using pneumatic technology to design a more reasonable body shape is the main way to reduce resistance, reduce fuel consumption, and improve fuel economy. In addition, a large number of vehicles using plastics, aluminum and other lightweight materials are manufactured
