Three sources are mainly responsible for the odors and air quality inside a vehicle (Vehicle Interior Air Quality):
Thus, three main areas can be identified for improving the air quality in vehicle interiors:
In all three areas, our experts at Fraunhofer IBP can help you optimize the air quality and comfort inside your vehicle. Get in touch with us, tell us about your problem and, together with you, we will find a suitable solution.
The topic concerning the quality of the air inside vehicles is often referred to by the term Vehicle Interior Air Quality, or VIAQ for short. The concentrations of volatile organic compounds (VOCs) in the vehicle interior are recorded as part of a measurement of the complete vehicle, determination of the interior air quality and measurement of emissions from the components. The tests we carry out are based on common standards (e.g. ISO 12219-1 and -7, GB/T 27630-2011). We also perform tests according to manufacturer specifications. If any abnormalities are identified, we can carry out further emission measurements on the components and make an odor evaluation of the vehicle in order to identify the source of the emissions or odors.
As part of the VIAQ test, we can test the efficiency of such air filters on our filter test bench and in the vehicle. We use a broad selection of pollutants:
In the IATC, the Indoor Air Test Center, the effect of ventilation settings on indoor air quality in vehicles can be reproducibly recorded. The IATC consists of a complete vehicle test chamber and a special supply air system, via which a variety of pollutants can be added to the supply air in a controlled manner in order to generate a reproducible pollutant atmosphere. Simultaneous measurement of pollutant concentrations in the vehicle cabin and in the overall vehicle test chamber can be used to determine the effect of the ventilation setting or sensor-based ventilation control system on the quality of the air inside the vehicle. Thus, we have a wide range of tools at our disposal for optimizing automatic ventilation controls in vehicles.
