英国Peteborough消息——当发动机汽缸运转时,其内部会发生些什么呢?Perkins Engines公司的研究人员发现,用激光多普勒风速计可以在不影响发动机工作的情况下,精确地测量汽缸或其管道内空气、燃气和燃料微滴的运动。他们用一个体积大约为0.01毫米~3的探针测量各种流体的运动;使光学系统扫描,给出汽缸特性的完整图象。该系统的微型电子计算机能够不停运地对发动机循环系统的任一部分进行测量,一直可测到旋转十弧分的曲柄角度。英国原子能科学研究中心曾把这种风速和风向测定系统当作该机构内燃机研究计划 Peteborough, UK - What happens inside the engine cylinder when it is operating? Researchers at Perkins Engines have found that a laser Doppler anemometer can accurately measure a cylinder or its Movement of air, gas and fuel droplets within the pipe. They measure the motion of various fluids with a probe measuring approximately 0.01 mm3; scanning the optical system to give a complete picture of the characteristics of the cylinder. The system’s miniature computer is capable of measuring any part of the engine’s circulatory system without stopping, always measuring a crank angle of ten arc minutes. The British Atomic Energy Research Center has the wind speed and wind direction measuring system as the agency’s internal combustion engine research program
