Forward Simulation Study on the Emission Characteristics of Volatile Organic Compounds in Cars

Volatile organic compounds (VOC), represented by formaldehyde and benzene, are highly carcinogenic and teratogenic, and can easily cause dizziness, nausea, vomiting and other illnesses. Their emission characteristics have a significant risk to the physical and mental health of passengers. The forward simulation of the emission characteristics of VOC in cars has become one of the important technical challenges for the automotive industry. In order to solve this problem, the emission and adsorption characteristics of VOC from interior parts of a car were investigated through a multi-interior coexistence experimental system. Based on this, a VOC emission prediction model was proposed in combination with the mass conservation law of VOC in the car and Henry's law of VOC, and validated by engineering amplification for 22 pieces of interior co-existence simulated final assembly experiments, illustrating that the relative standard deviations of the model for VOC in the car were 30.0% (benzene), 50.0% (toluene), -9.8% (ethylbenzene), 10.0% (xylene), -23.5% (formaldehyde), and -28.9% (acetaldehyde), respectively, with good prediction effect, which are able to greatly meet engineering needs.
