甲醇燃料汽车非常规排放成分测量装置的设计

DESIGN OF MEASUREMENT EQUIPMENT USED FOR INSPECTING UNREGULATED EXHAUST FROM METHANOL-FUELED VEHICLES

根据朗伯-比尔吸收定律和气体对红外线的选择性吸收规律,提出用红外法检测甲醇燃料汽车非常规排放成分含量的方法。设计了甲醇燃料汽车非常规排放成分红外测量装置,给出实施控制电路,主要用于对甲醇、甲醛、甲酸、苯等浓度进行检测分析,补偿修正了大气压力和环境温度对于测量结果的影响,最终实现测量结果的显示和打印输出。

According to the Lambert-Beer's laws and the selective absorption of gas on infrared, the infrared method to examine the unregulated exhaust from methanol-fueled vehicles is put forward.The measurement equipment of unregulated exhaust from methanol-fueled vehicles was designed and the controlling electrocircuit board was designed.The system is mostly used to analyze the concentration of methanol, formaldehyde,formic acid and benzene to rectify the result caused by environmental temperature and air pressure.The inspection results are displayed and printed with the measurement equipment finally.
