近二十年小车变化最大的是重量。因为安全和撞击测试的要求,车架车身变得愈来愈坚固,钢板多了厚了,重量自然增加,所以其他零件就要用上较轻的金属来抵消重量的增加。铝合金零件在小车内所占的比重比过去20年多了十几至二十倍,我在这行业不到10年,却清楚体会到它惊人的发展速度。不久前到意大利公干,坦白说我们这一行人到意大利都抱着类似朝圣的心态。你可能以为欧洲做引擎、变速箱最厉害的是德国,却不知道德国或者其他西欧国家的铝铸件、模具或相关设备很多都是从意大利买来的。这次我也看到好几家中国品牌和合资车厂所订购的模具和压铸设备正在调整测试,也许这对引擎国产化而言,将会开始一个新的局面。但说到此行最大的收获反而不是上述的东西,因为那些我早就知道。这次最大的收获
Nearly two decades the biggest change is the weight of the car. Because of the safety and crash testing requirements, the bodywork of the frame becomes stronger and stronger, the steel plate is thicker and the weight is naturally increased, so other parts should use the lighter metal to offset the weight increase. Aluminum alloy parts in the car than the proportion of the past 20 years more than ten to twenty times, I am in this industry less than 10 years, but clearly understand its alarming rate of development. Not long ago I went to work in Italy, frankly, we are pedestrians in Italy are similar to the attitude of pilgrimage. You may think that Europe is the engine, the most powerful gearbox is Germany, but do not know Germany or other Western European countries, aluminum die casting, mold or related equipment are mostly bought from Italy. This time I also saw that several molds and die-casting equipment ordered by several Chinese brands and joint-venture carmakers are being tested. Maybe this will start a new situation for engine localization. But when it comes to the biggest gain in this trip, it is not something that is mentioned above, because I knew it long ago. The biggest gain this time
