Strategies to control emissions of oxides of nitrogen from diesel engines can significantly increase the amount of emitted nitrogen dioxide (NO2) relative to nitric oxide (NO), which is tantamount to direct emission of ozone, a primary component of smog. The goal of this IRP is to develop an instrument that is capable of directly measuring NO2 in the presence of the very large levels of NO emitted from combustion sources such as diesel engines. The instrument will be used to evaluate emissions of NO2 and NO from a variety of vehicles to assess the magnitude of this potential air-quality issue.
