摘要
机动车尾气遥测系统是可在车辆正常运行状态下完成汽车尾气排放检测的设备。该类设备的校准需要对尾气含量进行精确测定。通过配备有气体光谱分析校准仪的交错通挡板检测室,可实现对开放的光程上气体的形成气团,进行更快速地分析、检测;同时能够更典型地反映如机动车运动过程中,即动态情况下尾气气团的污染的物理化学变化状态,具有广阔的应用前景及数据精度。
Vehicle exhaust remote sensing system is a kind of equipment which can complete the vehicle exhaust emission detection under the normal operation of the vehicle. The calibration of such equipment requires accurate determination of exhaust gas content. Through the staggered baffle detection chamber equipped with gas spectrum analysis calibrator, the gas formed in the open optical path can be analyzed and detected more quickly;At the same time, it can more typically reflect the physical and chemical changes of exhaust gas pollution in the process of motor vehicle movement, i.e. dynamic situation. It has broad application prospects and data accuracy.
