ef_ldv_cold_list | R Documentation |
This function creates a list of functions of cold start emission factors considering different euro emission standard to the elements of the list.
ef_ldv_cold_list(df, v = "LDV", ta, cc, f, eu, p)
df |
Dataframe with local emission factor |
v |
Category vehicle: "LDV" |
ta |
ambient temperature. Montly average van be used |
cc |
Size of engine in cc: <=1400", "1400_2000" and ">2000" |
f |
Type of fuel: "G" or "D" |
eu |
character vector of euro standards: "PRE", "I", "II", "III", "IV", "V", "VI" or "VIc". |
p |
Pollutant: "CO", "FC", "NOx", "HC" or "PM" |
A list of cold start emission factors g/km
The length of the list should be equal to the name of the age categories of a specific type of vehicle
