Relations between emissions and fuel properties for diesel heavy-duty vehicles based on EMEP/EEA. Function based on values from the EMEP/EEA air pollutant emission inventory guidebook 2019. Estimates are given by the ratio between correction factor of improved fuel by the correction factor of base fuel.
fuel_correction(
pollutant,
euro_stage,
improved_fuel = c(den = 835, s = 40, pah = 5, cn = 53, t95 = 320)
)numeric. A fuel correction factor.
character. Pollutant classified in "CO", "VOC", "NOx" or "PM10".
character. EURO period of vehicle, classified in "PRE", "I", "II", "III", "IV", "V" and "VI".
numeric. Numeric vector for characteristics of an improved fuel, ordered by: den (Density at 15 degrees C), s (Sulphur content in ppm), pah (Polycyclic aromatics content in \ number), t95 (Back end distillation in degrees C). Default input uses c(den = 835, s = 40, pah = 5, cn = 53, t95 = 320).
