福特汽车公司的研究人员将激光用于观察内燃机气缸内部工况.用激光器照射玻璃模拟装置来分析燃烧室内部的气体运动状况. 模拟装置的气缸、气缸盖、气门机构和曲轴均为模型,其转速略低于金属发动机,但使用氟利昂(一种惰性气体,其密度比空气大10倍), Researchers at Ford Motor Company used the laser to observe the internal conditions of the internal combustion engine cylinder and analyzed the gas movement inside the combustion chamber by irradiating the glass simulator with a laser.The model cylinder, cylinder head, valve train and crankshaft were all models of Slightly lower than the metal engine speed, but the use of Freon (an inert gas, the density of air 10 times larger)
