甲醛具有致癌性,可对人体健康造成危害,因此甲醇汽车的甲醛排放检测方法受到了人们的关注。文章利用常规排放的检测方法取得汽车尾气的稀释样气,从中抽取一定量的排气样气,由高效液相色谱仪分析甲醛的质量浓度。根据试验时测定的体积及试验循环行驶距离,得出与常规排放量纲完全一致的甲醛排放量。解决了甲醇汽车尾气排放中甲醛体积分数的测试问题。

Formaldehyde is carcinogenic to human,and it is harmful to human health. Formaldehyde emission detection methods of methanol vehicle are paid more and more concern. Using normal detection methods to gain diluted samples of automotive exhaust, extracting amount of sample, mass concentration of methanol is analyzed by high performance liquid chromatograph. Based on determinated volume and cycle distance, formaldehyde emission consistent with normal emission dimension is gained. The detection problem of formaldehyde volume fraction in methanol vehicle emission is solved.
