Emissions were monitored from transit buses to determine the difference in emissions between engine technologies and model years. The Environmental Protection Agency’s newest emissions standards set into law in 2007 and 2010 limited the level of emissions transit buses and other heavy-duty vehicles are able to produce. For the most part, these standards have been regulated in lab. My research looked at the emissions from these buses on-road, under normal operating conditions. At the Federal Way Transit Center, four types of bus engines were analyzed: conventional diesel, diesel with catalytic emission control, compressed natural gas, and diesel-electric hybrid. A remote sensing device was used to look at each of the buses emissions of CO, NO, HC, NO2, and NH3.
