Research on the Present Situation and Factors of Volatile Organic Compounds in Car Cabin

摘要

This article analyzed cabin indoor VOCs emission of more than 400 vehicles in attainment rate, average concentration and distribution situation. Result showed that in the past two years, the average concentrations of VOCs in vehicle decreased, but the overall compliance rate was still not high, acetaldehyde becoming limiting factor of overall compliance level. Meanwhile, this paper studies the relationship between sampling time, temperature, seasonal factors and VOCs detection results. The results provide a basis for the revision of the vehicle VOCs testing standards and manufacturing enterprise can use it to predict VOCs detection results.
