7月13日,一支重卡车队悄然驶出中国重汽技术中心的大门。在这酷暑难当的季节,他们的目的地却是号称“火洲”的新疆吐鲁番。但是这对随车队出发的中国重汽技术中心的“三高”实验团队来说,早已习以为常。从2006年开始,几乎每年,他们都要在盛夏时节去寻找最热的地方,最寒冷的冬天奔向滴水成冰之地。汽车的“三高”实验是指高温、高原、高寒实验。在这三种极端天气和气候条件下,对发动机、关键零部件及整车的性能进行测试和标定。这次的实验车队由三辆HOWO- July 13, a heavy truck fleet quietly pulled out of the center of China National Heavy Duty Truck Technology Center. In this extremely difficult season, their destination is Turpan, Xinjiang, which is known as the “Fire Island”. However, this has long accustomed to the “three-highs” experimental team of CNHTC Technology Center that started with the team. From 2006 onwards, almost every year, they are looking for the hottest places during midsummer and the coldest winter drifts. The car “three high ” experiment means high temperature, plateau, alpine experiment. In these three extreme weather and climatic conditions, the engine, key components and vehicle performance testing and calibration. The experimental team consists of three HOWO-
