Some preliminary observations
HC emissions (g/km) depend strongly on the first seconds (ca. 60 sec.) of the test cycles
CO emissions are related to the first seconds and to the high speed sections of the test cycles
Both HC and CO emissions show limited correlation with the “dynamicity” of the test cycles
NOx emissions, in addition to the first seconds, appear to be more correlated to the dynamicity of the test cycles
