The development of an accurate and reliable model, capable of determining the concentration of different VOCs in a car cabin as a function of time, is the focus of a research project in the atmospheric chemistry research group, headed by Gavin Edwards. Dr. Edwards and his students are working on this project that involves a collaboration between EMU and the "Big Three" automakers in Detroit, as part of the United States Council for Automotive Research (USCAR) project. Currently, Dr. Edwards' group are trying to model VOCs from chamber experiments done at the Ford Motor Company. They hope that their models can be shown to work in chambers and then be scaled to automobile level analysis. Preliminary testing of these model has shown promise. Varying time points for sample collection, and various parameters such as VOC starting concentration and chamber temperature have been shown to play important roles in emission rates. Further experimental comparisons, statistical analyses, and model sensitivity testing will need to be done in the future as the project and collaboration continues.
