A remote vehicle exhaust sensor (Fuel Efficiency Automobile Test, FEAT), developed at the University of Denver, collected the data sets. FEAT measures vehicle exhaust gases as a ratio to exhaust CO 2 because the path length of the plume is unknown, and the ratios are constant for a given exhaust plume. Technol. ,
The presence of oxygen in the fuel has the potential to lower the exhaust particle number concentration in diesel engines, they concluded. Despite these benefits, particulates and NO x emitted from diesel engines are of major concern for the environment. The accumulation mode ranges in size from about 50 nm to 500 nm. 2013.05.013.
