ef_im calculate the theoretical emission factors of vehicles.
The approache is different from including deterioration factors
emis_det) but similar, because they represent how much emits
a vehicle with a normal deterioration, but that it will pass the
Inspection and Manteinance program.
ef_im(ef, tc, amileage, max_amileage, max_ef, verbose = TRUE)
Numeric; emission factors of vehicles with 0 mileage (new vehicles).
Numeric; rate of growth of emissions by year of use.
Numeric; Accumulated mileage by age of use.
Numeric; Max accumulated mileage. This means that after this value, mileage is constant.
Numeric; Max ef. This means that after this value, ef is constant.
Logical; if you want detailed description.
An emission factor of a deteriorated vehicle under normal conditions which would be approved in a inspection and mantainence program.
