FRAQS
The goal of the Northern Front Range Air Quality Study (NFRAQS) is to determine the fraction of ambient particulate matter (PM) originating from various sources. As a part of that effort the Colorado School of Mines/Colorado Institute for Fuels and High Altitude Engine Research (CIFER) proposed to perform in use emissions measurements from several medium and heavy-duty diesel fueled vehicles. This testing will be performed in CIFER's heavy-duty chassis dynamometer laboratory. Summary Provided By: http://www.mines.edu/research/cifer/research/NFRAQS.html
