| Abstract | An on-board tailpipe emissions instrumentation system was designed, assembled and tested as proof-of-concept for the University of Vermont’s Transportation Research Center (TRC) Signature Project #2 “real-world” vehicle emissions data collection effort. This report summarizes the measurement system’s status as of June 2009 and demonstrates that the study team can reliably collect on-board emissions/vehicle performance data. The purpose of the new instrumentation package is to collect real-world exhaust emissions for regulated (CO, HC, NOx) and unregulated (CO2, air toxics, particle number) pollutant species as well as vehicle operating parameters, all at 1Hz temporal resolution, while a test vehicle is driven on the road network in Chittenden County, Vermont. Future data collected using the on-board system will be used to model the modal emissions of alternative vehicles. This report documents (i) the instrumentation system’s components and the research team’s proposed data collection methodology; and (ii) presents initial data sets collected by quantifying real-world emissions from a 1999 Toyota Sienna minivan that was used in previous studies. Unlike previous studies, however, the new instrumentation package collects: (i) the full number distributions of particle emissions using a particle spectrometer instrument that was not available previously; and (ii) quantifies mobile source air toxic (MSAT) gaseous emissions in addition to criteria pollutant (CO, NOx, HC) and greenhouse gas (CO2, N2O, CH4) using a high-speed Fourier Transform Infrared Spectroscopy (FTIR) instrument specifically designed for on-board vehicle exhaust testing. |
