In-Use Measurement Of Locomotive Emissions, Matt Breuer
In-Use Measurement Of Locomotive Emissions, Matt Breuer
Summer Research
The Environmental Protection Agency’s newest emissions standards set into law in 2004, which took effect in 2010, limited the level of emissions that locomotives are allowed to produce. For the most part, these standards have been verified in the laboratory and not while the locomotives were in actual use. My research looked at the emissions from these locomotives in-use, under normal operating conditions. The measurements took place on two Pierce County bridges that are above operating train tracks. A remote sensing device (the FEAT) was used to look at locomotive emissions of CO, HC, NO, NO2, SO2, …

Recent US EPA emissions regulations have resulted in lower emissions of particulate matter and oxides of nitrogen from heavy-duty diesel trucks. To accelerate fleet turnover the State of California in 2008 along with the Ports of Los Angeles and Long Beach (San Pedro Bay Ports) in 2006 passed regulations establishing timelines forcing the retirement of older diesel trucks. On-road emissions measurements of heavy-duty diesel trucks were collected over a three-year period, beginning in 2008, at a Port of Los Angeles location and an inland weigh station on the Riverside freeway (CA SR91). At the Port location the mean fleet age …

As part of the 2010 Van Nuys tunnel study, researchers from the University of Denver measured on-road fuel-specific light-duty vehicle emissions from nearly 13,000 vehicles on Sherman Way (0.4 miles west of the tunnel) in Van Nuys, CA with its multi-species FEAT remote sensor a week ahead of the tunnel measurements. The remote sensing mean gram per kilogram carbon monoxide (CO), hydrocarbons (HC), and oxides of nitrogen (NOx) measurements are 8.9% lower, 41%, and 24% higher than the tunnel measurements respectively. The remote sensing CO/NOx and HC/NOx mass ratios are 28% lower and 20% higher than …
