据美刊报道,美国橡树岭国家实验室的科学家正在研制一种可根据不同汽车功率要求而发生“尺寸变化”的新型发动机。以磁流体力学为基础,综合磁流体和导电液体的运动特性,该发动可提供汽车要求的高性能,而成本又低于传统的内燃机,其8万公里寿命循环的燃烧效率为34～40公里/公升。 According to the American Journal, scientists at the Oak Ridge National Laboratory in the United States are developing a new engine that can “vary in size” depending on the car’s power requirements. Based on magnetohydrodynamics, which combines the magnetic properties of magnetic fluids and conductive liquids, this engine delivers the high performance demanded by automobiles at a lower cost than conventional internal combustion engines, with a combustion efficiency of 34 to 40 km for a 80,000 km life cycle /liter.
