Abstract The report summarizes results of tests to (1) evaluate the accuracy and precision of two different remote sensing devices (RSDs) for measuring carbon monoxide (CO), hydrocarbons (HCs), and nitric oxide (NO), and (2) evaluating the capabilities of three RSDs for characterizing fleet emissions of NO. 'Puff' tests (in which simulated motor vehicle exhaust gas was repeatedly injected in bursts or puffs into the RSDs) were conducted. The accuracy and precision of data from these measurements, which showed a generally linear response over a range of concentrations, were in the order CO > HCs > NO. Subsequently, three vehicles were driven at constant speed on a dynamometer and on a test track. The average emissions data measured by the three RSDs at the track, when compared to the dynanmometer emissions data (which were used as the standard), in general showed just the opposite result; i.e., NO > HCs > CO. However, the test track data showed a considerable amount of variation. The three RSDs were tested for several hours on a freeway ramp in Raleigh, NC.
