The previous section described the significant effect of the fuel flow rate on emissions when operating the on-wing engine below N1 = 25%. The data plotted in Figure IV-2 suggest that the magnitude of the influence of ambient temperature on the emission index is similar to the effect of engine operation at rotational speeds less than N1 = 25%.

during subsequent commercial aircraft tests. To compare the temperature dependence from test results for different CFM56 combustor types, as well as to examine the temperature dependence using other available VOC measurements, a normalization scheme is adopted.

. The resulting curve is the light blue line in Figure IV-3 and agrees very well with the empirical results despite the potential misapplication of BFFM2 to fuel flow below the 7% reference fuel flow.
