Temperature and driving cycle influence SVOC emissions from (bio-) diesel trucks

The present study examines the effects of fuel (an ultra-low sulfur diesel [ULSD] versus a 20% v/v soy-based biodiesel—80% v/v petroleum blend [B20]), temperature, load, vehicle, driving cycle, and active regeneration technology on gas- and particle-phase carbon emissions from light and medium heavy-duty diesel vehicles (L/MHDDV). The study is performed using chassis dynamometer facilities that support low temperature operation (-6.7 °C versus 21.7 °C) 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. This dataset is associated with the following publication: Hays, M., W. Preston, B. George, I. George, R. Snow, J. Faircloth, T. Long, R. Baldauf, and J. McDonald. Temperature and driving cycle significantly affect semi-volatile organic compound emissions from diesel trucks. ENERGY AND FUELS. American Chemical Society, Washington, DC, USA, 31(10): 11034-11042, (2017).
