The study is performed using chassis dynamometer facilities that support low temperature operation (-6.7 \u00b0C versus 21.7 \u00b0C) and heavy loads up to 12,000 kg. Organic and elemental carbon (OC-EC) composition of aerosol particles is determined using a thermal-optical technique. Gas- and particle-phase semivolatile organic compound (SVOC) emissions collected using traditional filter and polyurethane foam (PUF) sampling media are analyzed using advanced gas chromatograpy/mass spectrometry (GC/MS) methods. \n\nThis dataset is associated with the following publication:\nHays, M., W.
