Audio Spot: Tracking truck emissions
An adsorber serves as a catalyst in reducing the amounts of oxides of nitrogen, transforming the emissions into harmless nitrogen. The SpaciMS can characterize and measure the different chemicals present in the catalyst, and how those change over time as the NOx is converted to nitrogen.
The SpaciMS contributes to increasing fuel efficiency while meeting upcoming new emissions standards. The technology will allow a more accurate reading of the chemical makeup of truck exhaust and emissions under the stricter federal diesel emissions standards to take effect in 2007.
