ABSTRACT

To determine the main reasons of out-of-control of vehicle interior air quality (VIAQ) during mass production, we constructed a three physical field coupling simulation model, which included dilute matter transfer, volatile organic compounds (VOCs) distribution across temperature ranges, and VOCs convective flow. Effects of storage temperature, ventilation rate, ventilation pollution, storage time, and emission difficulty on the VOCs concentration of a sample of interior materials were quantitatively analyzed. Simulation results showed that storage temperature fluctuation could cause an emittable concentration increase of up to 71% at 25℃, which was the most likely out-of-control reason of VIAQ; ventilation pollution can significantly contribute to uncontrolled vehicle air quality with up to 82% concentration increase; fluctuations in ventilation rate and interior materials that are less likely to emit VOCs would not cause the VIAQ to be out of control; higher heating devolatilization temperatures can result in a faster reduction of emittable concentration in the interior materials at 25 ˚C.
