Research the Application of Optical Fibre Sensor On Internal Combustion Engine Platform Chen Hanxun;Zhao Qiping;Chen Sanmei;Xu Dawei(Assoc.Prof.,Institute of Wuhan Technology, Wuhan 430070,China.)This article introduced the application methods of optical fibre sensor on internal combustion engine platform and have been applicated. Through researching the experiments for some optical fibre sensors,it is proved advantages of the application of optical fibre sensor on internal combustion engine platform. It given the platform structure and assignment about using optical fribre sensor measure.:optical fibre sensor;platform;resist disturbance;light source
