... , respectively; the wide ranges of ambient conditions impacted the engine operation and therefore the emissions data; some of the apparent variations in the measured data have been traced to changes in ambient conditions; ambient submicron particle concentrations measured at the testing site were typically <5 μg/m3) , as well as engine temperatures, fuel flow rates, and fan speeds, were carefully documented for each of the test points examined during the experiment.
