fuel_corr: Correction due Fuel effects

Description

Take into account the effect of better fuels on vehicles with older technology. If the ratio is less than 1, return 1. It means that it is nota degradation function.

Usage

fuel_corr(euro, g = c(e100 = 52, aro = 39, o2 = 0.4, e150 = 86, olefin =
  10, s = 165), d = c(den = 840, pah = 9, cn = 51, t95 = 350, s = 400))

Arguments
